Abstract:

It is widely known that petroleum hydrocarbons constitute one of the most hazardous pollutants that affect human and environmental health. The ongoing research on bioremediation with petroleum hydrocarbon-degrading bacteria has shown tremendous promise of the technology due to its advantages of high efficiency and eco-friendly nature. To this end, studies have been carried out to identify a large amount of bacterial species with petroleum hydrocarbon-degrading ability for applications in bioremediation. Here, we present a brief perspective of some of the notable advances in oil degrading bacteria and the remedial actions for decontamination of water and soil along with recovering the spilled materials at oil sites.

Abstract:

Introduction. Wastewater contaminated with oil, demulsifiers, hydrogen sulfide, ammonium sulfide, phenol, sulfates, aromatic hydrocarbons, alkali, fatty acids, various solutes, etc. is formed at oil refining and petrochemical enterprises. Runoff entering surface and underground water sources can harm water quality, sanitary conditions of life, and water use of the population. Taking this into account, further improvement of scientific approaches to ensure the safety of water bodies that are sources of drinking and recreational use, assessment, and prevention of public health risks caused by water factors is of particular importance. Material and methods. To assess the degree of influence of industrial enterprises on the quality of water sources, we studied the sanitary condition of the Belaya River and its tributaries, as well as underground water lying in the area of oil refining and petrochemical industries. The analysis of the water quality of surface and underground water sources according to the data of laboratory studies of departmental laboratories; the results of scientific and practical research and publications on the studied problem for 1999-2019. Results. Materials of observation data show that wastewater from changes of industrial enterprises the sanitary condition of surface reservoirs: there is a decrease in the content of ammonium nitrogen and biological oxygen consumption indices and a significant increase in the content of nitrates, chlorides, sulfates, and petroleum products. Surface water sources are characterized by unfavorable organoleptic characteristics, high organic pollution, and the presence of specific compounds (petroleum products, surfactants, alpha-methylstyrol, benzene, toluene, isopropylbenzene, and hydrogen sulfide) in concentrations higher than their hygiene regulations. Underground waters located on the territories of the main industrial complexes are characterized by high mineralization, extremely high hardness, high content of iron, nitrates, and petroleum products. Conclusion. Refineries and petrochemicals affect the pollution of surface and underground water sources. The water quality of the surveyed water bodies does not meet sanitary and hygienic standards. The priority indices of the influence of the enterprises of branch on water bodies include organoleptic indices of organic pollution indices of total salts composition of water, the content of specific ingredients: oil, benzene, toluene, isopropyl, alpha-methyl styrene, xylene, cresol, kerosene, gasoline, fuel oil, ethylene, propylene, 3,4-benzo(a)pyrene, phenols (volatile), methyl mercaptan, nonionic and anion-active surfactants, biological oxygen consumption indices and others. The research made it possible to assess the level of pollution of water bodies located in the zone of industrial enterprises and develop measures to reduce the man-made impact on the environment and public health.

Abstract:

A crude oil spill is a common issue during offshore oil drilling, transport and transfer to onshore. Second, the production of petroleum refinery effluent is known to cause pollution due to its toxic effluent discharge. Sea habitats and onshore soil biota are affected by total petroleum hydrocarbons (TPH) as a pollutant in their natural environment. Crude oil pollution in seawater, estuaries and beaches requires an efficient process of cleaning. To remove crude oil pollutants from seawater, various physicochemical and biological treatment methods have been applied worldwide. A biological treatment method using bacteria, fungi and algae has recently gained a lot of attention due to its efficiency and lower cost. This review introduces various studies related to the bioremediation of crude oil, TPH and related petroleum products by bioaugmentation and biostimulation or both together. Bioremediation studies mentioned in this paper can be used for treatment such as emulsified residual spilled oil in seawater with floating oil spill containment booms as an enclosed basin such as a bioreactor, for petroleum hydrocarbons as a pollutant that will help environmental researchers solve these problems and completely clean-up oil spills in seawater.

Abstract:

SUMMARYGroundwater has been extensively exploited worldwide but is now confronted by a variety of problems, including groundwater depletion and contamination, that threaten its sustainable use as a clean water source. Groundwater is one of the major sources of water for domestic, agricultural and industrial uses, and provides 13% of the total annual water supply in Korea. Annual groundwater use has continuously increased from 2.57 billion m3 in 1994 to 3.72 billion m3 in 2007, of which 48.1% was consumed for domestic purposes. However, due to imprudent groundwater development and inappropriate management, Korea has confronted some critical groundwater problems, including extensive water level decline and quality deterioration caused by petroleum hydrocarbons and chlorinated solvents. Among 193 national groundwater deep-monitoring wells nationwide, 62% showed decreasing water levels over the period 2004–2008. Soil and groundwater contamination by petroleum hydrocarbons was detected at a great number of military bases and public facilities, which drew national attention and complaints. The presence of high levels of radionuclides such as uranium and radon in groundwater has awakened controversy on their health effects. Increasing outbreaks of massive gastroenteritis were attributed to noroviruses in contaminated groundwater, and raised public health concerns. In addition, chlorinated solvents, especially trichloroethylene (TCE), have been frequently found in urban and industrial groundwaters, further adding to the burdens of environmental authorities. Consequently, these groundwater-related environmental issues have forced the Korean government and relevant authorities to urgently devise mitigation plans to secure a sustainable future use of groundwater resources. This paper provides details of the groundwater issues and implications for appropriate development and management.

Abstract:

A great variety of fluorescing compounds - mainly polycyclic aromatic hydrocarbons (PAHs) which are of concern in environmental and public health risk assessment due to their carcinogenic properties - exists as a complex mixture in petroleum, which makes their separation and identification difficult, if not impossible. Ultraviolet (UV) fluorescence spectroscopy offers a relatively simple way to characterize and quantify these compounds in environmental samples. PAHs are known to be sensitive to photochemical reactions rather than to biological oxidation. Several studies carried out with pure PAH compounds demonstrated their fast photolysis, half-lives of a few minutes to a few hours have been observed, which depend on the irradiation light flux. The objective of the present study was to describe photolysis characteristics of mixtures of fluorescing petroleum compounds exposed to sunlight. Crude oil and benzo(a)pyrene (BaP) were used as model mixture of fluorescing compounds in seawater. Solar irradiation conditions were selected to characterize maximum photolysis rates at 29 °N latitude. In addition to the characteristics of the irradiation light, reactor geometry, level of dispersion of the petroleum compounds and the presence of particulate matter influenced significantly the reaction rate coefficients. Photolysis of BaP was described with a first-order rate coefficient, whereas photolysis of the other compounds, quantified by fluorescence intensity at different wavelengths, was characterized with a multicomponent equation. BaP can be considered as an internal actinometer in photolysis experiments with PAH mixtures. The level of dispersion affected the photolysis rates, which were highest in the dissolved and chemically dispersed samples. Ratios between fluorescence intensities at different wavelengths allowed comparison with the characteristics of actual environmental samples, providing additional information on their weathering history.

Abstract:

During the production and transportation of petroleum hydrocarbons, unsuitable operation and leakage may result in contamination of water and soil with petroleum hydrocarbons. Petroleum contamination causes significant marine environmental impacts and presents substantial hazards to human health. Bioremediation of contaminated water and soil is currently the effective and least harmful method of removing petroleum hydrocarbons from the environment. To improve the survival and retention of the bioremediation agents in the contaminated sites, microbial cells must be immobilized. It was demonstrated that immobilized microbial cells present advantages for degrading petroleum hydrocarbon pollutants compared to free suspended cells. In this study, the ability of a Bacillus strain (designed as Bacillus sp. VTVK15) to immobilize on PUF and to degrade crude oil was investigated. The immobilized Bacilllus strain had the highest number (5.38 ± 0.12 Í 108 CFU/g PUF) and a maximum attachment efficiency of 92% on PUF after 8 days. Analysis by GC-MS revealed that both free and immobilized cells of Bacillus sp. VTVK15 were able to degrade 65 and 90% of the hydrocarbons in 2% (v/v) crude oil tested after 14 days, respectively. The results suggest the potential of using PUF-immobilized Bacillus sp. VTVK15 to bioremediate petroleum hydrocarbons in an open marine environment.

Abstract:

Unleaded gasoline consists of over 100 chemicals. The risk assessment strategy proposed identifies benzene, toluene, ethylbenzene, (o-, m-, p-) xylenes, n-hexane and methyl-tertiary-butyl ether (MTBE) as the major components of health concern for humans from the migration of unleaded gasoline to groundwater and/or other potential drinking water sources. The mixtures model for human exposure to drinking water contaminated with unleaded gasoline proposed indicates that the greatest proportion of the total health risk is due to cancer risk from the benzene component. The extensive migration of the unleaded gasoline additive MTBE in groundwater indicates that human exposure guidelines are needed to protect human health. This paper proposes a maximum level of 0.2 mg MTBE/L in groundwater/drinking water to protect from potential central nervous system (CNS) depressant and other toxicity. More limited human exposure to contaminated air due to gasoline releases may occur. A mixtures model based upon limited dose-response data for expected predominant air components is also proposed.

Abstract:

The increasing need for fuel derived from petroleum is also in line with the increased exploration and production activities of petroleum. Besides producing crude oil products, this activity also produces petroleum waste. This waste will pollute the soil which will have an impact on environmental damage, disruption of human health and other living things. Therefore according to Veegha (2008), an efficient and environmentally friendly method for treating petroleum waste is needed. One of the waste treatment methods is using phytoremediation method. Phytoremediation is defined as a technology for cleaning, removing or reducing harmful pollutants, such as heavy metals, pesticides, and toxic organic compounds in soil or water using the help of plants. This research was conducted for three months from September to November 2019 at the open nursery of PT. CPI with paranet shade 60%. This study aims to determine the effectiveness of bahia grass (P. notatum) in degrading Total Petroleum Hydrocarbon (TPH) in petroleum-contaminated soils in the Rokan Block PT. Chevron Pacific Indonesia and analyze the socio-economic impact of phytoremediation on local communities. The results showed that the effectiveness of Bahia (P. notatum) grass proved effective in reducing the concentration of Total Petroleum Hydrocarbon (TPH) in petroleum-contaminated soils in the Rokan Block operating area of PT. Chevron Pacific Indonesia. The percentage of effectiveness shows a decrease in value of up to 58.38%. The socio-economic impact of phytoremediation on local communities has a positive impact with the planned phytoremediation activities using bahia grass with the community as work agents for planting the grass.

Abstract:

Soil contamination by gasoline underground storage tanks is a critical environmental problem. The results herein show that in situ bioremediation using indigenous soil microorganisms is the method of choice. Five sites were selected for bioremediation based on the levels of benzene, toluene, ethylbenzene and xylene and the amount of total petroleum hydrocarbons in the soil. Bacteria capable of degrading these contaminants were selected from the contaminated sites and grown in 1,200 I mass cultures. These were added to the soil together with nutrients, water and air via PVC pipes.

Abstract:

Calcined coke is a high quality carbon material produced by calcining green petroleum coke. Calcining is the process of heating green petroleum coke in a kiln to remove excess moisture, extract all remaining hydrocarbons, and modify the crystalline structure of the coke into a denser, electrically conductive product. The final product, calcined coke, is primarily used to make carbon anodes for the aluminum industry and recarburizing agent for industries such as the steel industry. If not appropriately controlled, the calcining process could lead to excess production of particulate emissions from either handling or storing of raw coke, or from the stack emissions during the production of calcined coke. Though calcined coke has shown low hazard potential in human populations due to low volatile content, there remains some public health concern regarding the emissions from these facilities. This study is designed to evaluate the emissions of petroleum coke calcining facility and assess the public health concern from the processes engaged in the handling and storage of green coke as well as from the calcining process. The ambient air levels were measured from a calcining facility and compared with the standards promulgated by USEPA. The results showed that pollutant contribution from the facility, measured by monitoring carbon fraction of the emissions, was de-minimis. The current research also studied whether the exposure levels and health risks specified in various epidemiological studies correlate with the standards promulgated by USEPA to protect public health from petrochemical emissions.

Abstract:

Efforts to manage eutrophication of surface waters should recognize that macropore flow transports significantly more phosphorus (P) to surface waters via tile drains than water that percolates through the soil matrix. For the watershed-scale SWAT (Soil and Water Assessment Tool) model to describe phosphorus transport through tile drains, SWAT needs to partition percolation into macropore flow and matrix flow. The objective of this study was to evaluate the effects of a new macropore flow algorithm on the partitioning of hydrological flows, using input data that are readily available, consistent with the current approach to SWAT modeling. The algorithm was evaluated in a proof of concept outside of SWAT and within a re-conceptualized version, SWAT-QC2. The proof of concept reproduced episodic macropore flows, which increased with greater daily rainfall if infiltration exceeded a threshold that was lower for finer-textured soils. Although the algorithm did not improve predictions of streamflow of an agricultural subwatershed in southern Quebec (30 km2), the algorithm improved SWAT's partitioning between surface runoff and subsurface flow. SWAT-QC2 also predicted reasonably the separation between macropore and matrix components of subsurface flow, upon comparison with results from a chemical-based hydrograph separation of the subwatershed's streamflow. As in the proof of concept, the predicted amount of macropore flow into tile drains was greater under finer-textured soils than coarser-textured soils. By describing the portion of percolation that flows through macropores and potentially controls subsurface P transport, the macropore flow algorithm provides a framework for future developments of SWAT that describe macropore transport of P to tile drains. To improve the partitioning between macropore and matrix flows, future developments of SWAT-QC2 should account for dynamic macropore connectivity and the effects of soil moisture on macropore flow, but more research is needed to determine experimentally the spatiotemporal variation of macropore flow in agricultural soils.<br>Les stratégies d'intervention ciblées sur la prévention de l'eutrophisation des eaux de surface en milieu agricole devraient prendre en compte que relativement plus de phosphore chemine vers les drains souterrains par les macropores du sol qu'en cheminement matriciel. Afin de décrire les phénomènes de transport de phosphore aux drains, le modèle hydrologique SWAT (Soil and Water Assessment Tool) doit être en mesure de distinguer ces processus de transfert. La présente étude avait pour objectif d'évaluer la performance d'un nouvel algorithme séparant les écoulements matriciels et préférentiels, en mettant à profit des jeux de données existantes et suivant une démarche compatible avec l'approche de modélisation inhérente à SWAT. L'algorithme a d'abord profité d'une validation conceptuelle, hors du modèle SWAT, puis d'une évaluation suivant son intégration à une nouvelle version du modèle hydrologique, SWAT-QC2. La validation conceptuelle de l'algorithme a démontré que les flux matriciels épisodiques prédits augmentent avec les précipitations journalières, à la condition que le taux d'infiltration ait atteint un seuil limite, relativement moins élevé en sol argileux. Bien que l'algorithme n'ait pas amélioré la prédiction du débit total d'un petit bassin versant du Sud du Québec (30 km2), il a néanmoins amélioré la performance du modèle SWAT à répartir les écoulements de surface et souterrains. La comparaison des prédictions du modèle hydrologique avec les résultats de séparation des hydrogrammes à l'exutoire du même bassin versant suivant une méthode chimique témoigne d'une performance réaliste de SWAT-QC2 à prédire la répartition des flux souterrains préférentiels et matriciels. A l'instar de la validation conceptuelle de l'algorithme, les flux préférentiels prédits sont relativement plus importants en sol argileux qu'en texture plus grossière. En décrivant la proportion des écoulements souterrains qui emprunte la voie préférentielle, et qui contrôle potentiellement les transferts souterrains de P, l'algorithme d'écoulement en macropores constitue une assise pour le développement ultérieur de SWAT intégrant une description des transferts souterrains de phosphore vers les drains souterrains. Afin d'améliorer la performance de SWAT-QC2 à séparer les flux préférentiels et matriciels, les développements futurs du modèle hydrologique devraient prendre en compte la nature dynamique de la connectivité des macropores, de même que les effets de l'humidité du sol sur l'écoulement préférentiel. Cette démarche appelle cependant à une meilleure caractérisation expérimentale de la variabilité spatio-temporelle des flux préférentiels en sols agricoles.

Abstract:

<p> Understanding the relationships between human health, water, sanitation, and environmental health is a requirement to understanding the challenges that face researchers when it comes to addressing global health relating to water and sanitation. Access to improved water and sanitation is not only a precondition to health, but to all aspects of daily living. Target 7.C of the Millennium Development Goals (MDGs) addresses worldwide disparities in access to improved water and sanitation by calling for the reduction in <i> "half of the proportion of people without sustainable access to safe drinking water and sanitation by 2015".</i> Over 90% of the population of Costa Rica has access to improved water and sanitation, thus exceeding the water and sanitation targets for the Millennium Development Goals (MDGs). Despite having access to water and sanitation, little is known whether communities are only interested in access or if quality and quantity of water and sanitation systems are as equally as important. Target 7.c of the MDGs does not include water quality in the definition of safe water. Furthermore, the use of the words "safe" and "improved" in the target are often interchanged and can be misleading, especially when considering the impact of water quality on population health. In Costa Rica, households in the Nandamojo watershed have access to improved water and sanitation; it is unclear whether the drinking water is potable with respect to Costa Rican and the World Health Organization (WHO) water quality standards. The impact of leaking septic systems on human and environmental health is also unknown. </p><p> Illnesses associated with recreational water are an increasing public health problem, causing a great burden of disease in bathers every year. The global health impact of infectious diseases associated with recreational water exposure has been estimated at around three million disability-adjusted life years (DALYs) per year, resulting in an estimated economic loss of around twelve billion dollars per year. Fecal and chemical contamination of recreational water is a concern, especially in areas of non-point source pollution. Health-based water monitoring is often conducted in recreational waters as a tool for assessing risk. In Costa Rica, recreational water sampling is conducted at coastal beach areas only, neglecting other surface waters used by residents and tourists. Community perspectives regarding recreational water use and the associated risks are limited. Understanding these perspectives will enable public health professionals to better target community needs, such as education and to address the concerns of participating communities. </p><p> This dissertation was divided into three chapters. The first chapter explored community perceptions on improved water and sanitation, the second chapter assessed community water systems and the risk of acute diarrheal disease, and the third chapter captured community perceptions on recreational water use and the risk of waterborne illness. Methodologies for water sampling and analyses were used to assess water quality, while household interviews and focus groups were conducted to capture qualitative data. </p><p> Results from the first chapter showed participants had positive perceptions towards their improved water and sanitation systems. Household interviews revealed almost half of the respondents had concerns with water quality, while less than 25% did not think their septic tanks leaked or overflowed during rain events. Focus group discussions revealed common themes. Participants identified water quality, health, pipes, water scarcity, odors, insects, and overflow/infiltration of water and sanitation to be important issues. Participants revealed convenience, improved health and safety and the lack of odors to be themes directly related to customer satisfaction of improved water and sanitation. </p><p> Results from the second study revealed 57% of household samples had total coliform bacteria above the Costa Rican standard for safe drinking water exceeding the single standard limit of zero, while 61% failed the World Health Organization standard for fecal coliforms exceeding the single standard limit of zero. AGII was identified in 41 of the 378 household residents (11%). The odds ratio for AGII among household residents with a water sample positive for total coliforms was 1.88 (0.81-3.17). Fecal coliforms were statistically significant for those with AGII (OR = 3.19, 1.43-7.12). Regression modeling analyses revealed individuals with AGII and household drinking water positive for fecal coliforms to be statistically significant (OR = 3.01, 1.33 - 6.84), while other covariates (total coliforms, gender, treated water, and families) also had odds ratios greater than one, but were not significant. </p><p> Results from the third chapter indicated most respondents felt recreational water sources, such as streams and rivers were contaminated with human, animal, and chemical wastes. Focus group participants also stated they did not use inland waters for recreational purposes for these reasons. However, many did admit using marine water for recreational bathing and felt these areas were not contaminated. These beliefs did coincide with the water quality results from freshwater sources, but not marine sources. Fecal coliform contamination was widespread throughout the watershed in freshwater sources. Marine water samples failed the World Health Organization (WHO) and Costa Rican recreational water standards for fecal coliform and enterococci in 36% and 6% of the samples, respectively. </p><p> The overall results of this dissertation suggest that the definitions of improved water and sanitation have to include, at a minimum, water quality, water quantity, proper construction and containment of storage tanks, and oversight and maintenance of these systems. Given the challenges facing communities in the Nandamojo watershed regarding water and sanitation, it is essential for scientists, researchers, policy makers, water committees, health providers, and community members to design and implement strategies in water resource management and proper waste management. Communities and water committees would also be best served if they worked with government agencies to conduct concurrent testing of both recreational water and drinking water, especially since both them target many of the same parameters.</p>

Abstract:

Since the passage of the Clean Water Act, concern about surface water quality has increased. Reducing exposure to pathogens and adverse impacts on human health because of contact with surface waters has become the focus of many regulatory agencies. Fecal pollution is often a cause of surface water impairment. Fecal indicators, such as fecal coliforms and Escherichia coli, are used as surrogates to evaluate the presence or absence of fecal pollution. However, a growing body of research has shown that these species lack key characteristics necessary to be adequate indicators. As such, explorations into the efficacy of indicator species in predicting fecal pollution in water are necessary. Sinking Creek is a tributary of the Watauga River Watershed, located in Northeast Tennessee. Approximately ten miles of Sinking Creek have been placed on the national 303(d) list for fecal pollution, denoting the presence of fecal contamination exceeding the regulatory limit. Salmonella and Aeromonas are two enteric pathogens that would be expected to be detected in fecally contaminated waters. The primary objective of this study was to detect the presence of Salmonella and Aeromonas in Sinking Creek. The secondary objective was to evaluate their relationship with fecal coliforms, E. coli, and water quality parameters. Six study sites along Sinking Creek were sampled and standard methods were used to enumerate Salmonella and Aeromonas. Samples for Salmonella were collected for 8 months, while samples for Aeromonas were collected for seven. Salmonella and Aeromonas were present in Sinking Creek. Salmonella had the highest concentration at site 2 (the most downstream site), and was detected during all months of the study except for November. Salmonella concentrations varied by site. Aeromonas was present only during colder months, and had the highest concentration at site 2. Both Salmonella and Aeromonas show qualitative relationships with water quality parameters, such as dissolved oxygen and conductivity. However, statistically significant correlations of Salmonella and Aeromonas with water quality parameters were not observed. The lack of statistical significance is partially due to large variability and a small data set. Neither Salmonella or Aeromonas exhibited a relationship with fecal coliforms or E. coli. Therefore, fecal coliforms and E. coli may not be adequate indicator species for the presence of Salmonella, Aeromonas and possibly other waterborne pathogens. Traditional indicator species may inflate risk of pathogen exposure. Thus, many water bodies may be unnecessarily deemed as impaired. The results from this study can be used to guide further research regarding covariates influencing pathogen densities at fecally contaminated sites, as well as to guide decisions regarding impaired surface waters and management techniques.

Full text

Abstract:

Abstract BB field complex redevelopment is an integrated development under PETRONAS Enhanced Oil Recovery (EOR) project. BB fields are producing fields operated by PETRONAS Carigali Sendirian Berhad (PCSB). The BB fields redevelopment is a project to redevelop both B1 and B2 fields and to enable EOR implementation in the B1 field. The B1 redevelopment includes the EOR implementation through immiscible water alternating gas (IWAG), infill drilling, and safeguarding of no further activity (NFA) production. The B1 redevelopment also incorporates some provisions for the B2 field to secure gas supply for B1 IWAG. The B2 redevelopment focuses on safeguarding B2 NFA production. The redevelopment consists of three main elements, 1) EOR IWAG that involves injector well drilling at a new IWAG injection wellhead platform, 2) infill drilling at existing platforms and 3) safeguarding of NFA. Surface facilities scope includes installing a new Central Processing Platform (CPP) for B1 field, wellhead platforms, and intra-field pipelines. The CPP includes 60 kbpd water injection plant capacity, gas compression, gas-liquid separation, and produced water treatment. Modification in the B2 field is to flow gas from the B2 field to the B1 field. Operational readiness is crucial to ensure that the integrated project is executed smoothly. Two cases for changes are new technology deployment for water injection module (WIM) and people capability. It is a big challenge to achieve an effective start-up with minimum delay. There are some important aspects considered includes operation philosophy, Health Safety and Environment (HSE), and collaborative working environment (CWE) implementation. It is important to ensure improving oil recovery through infill and IWAG. Best practices in operation readiness of an integrated project that have many challenges that include process, people, and technology. These best practices may be replicated in any other projects by other companies/operators.

Abstract:

Abstract This paper demonstrate a unique combination of techniques and equipment that enabled dynamic reservoir evaluation process using simplified Drill Stem Test (DST) string and completion accessories. The well testing was conducted on a shallow slanted offshore well, drilled into faulted reservoirs with multilayer and complex fluids environment. Key technical challenges to perform well testing includes designing a custom DST string to cater for the multilayer reservoir and articulating a surface well testing equipment that capable of efficient separation to ensure safe and environmental friendly disposal while having accurate flowrate measurements, to deliver good interpretable data given that the uncertainty and complexity of the formation and the well itself. During drilling campaign, contingency plan to mitigate against losses was implemented which had a significant impact on the well testing program. As such, uncertainty-based well test design and interpretation methodology was used to address this and to achieve well objectives. This involved numerical model analysis considering reservoir uncertainties and their interaction with each other, to identify which parameters can be interpret confidently and to indicate the test duration for the well testing program. Since the area is nearby to producing fields, several cases model based on reservoir pressure regime was also constructed during the design stage to tolerate flexibilities for the decision tree. The well testing was successfully conducted result from integrated approach to well test design and realtime data support throughout the operation along with innovative DST string design, customize completion accessories for multiple zones testing and adaptive intervention tools for highly deviated well. Matching with nearby wells were also conducted during monitoring to predict future pressure behaviour which allow for the duration of final build-up to be optimized. Given that Health, Safety and Environment (HSE) is the top of priority, an important aspect of the surface well testing package was the water treatment equipment to treat the produced water from reservoir before being discharge in order to guarantee safe environmental disposal. The well was successfully test at maximum flowrate 2,000bpd of oil and 20MMscf/d of gas with traces of produced water. Data gathered thru the Tubing Stem Test (TST) can used to interpret reservoir parameters and all the well testing objectives were successfully achieved despite the many challenges encountered during the drilling campaign and design stage. The end results may contradict traditional testing methods for pressure transient analysis, but hopefully this paper might create the opportunity to replicate TST as quick and effective reservoir evaluation in other parts of the world.

Full text

Abstract:

Abstract The Petroleum Working Group (PWG) of the United Nations Economic Commission for Europe (UNECE) has developed the Petroleum Resource Specifications and Guidelines (PRSG) to facilitate the application of the United Nations Framework Classification for Resources (UNFC) for evaluating and classifying petroleum projects. The UNFC was developed by the Expert Group on Resource Management (EGRM) and covers all resource sectors such as minerals, petroleum, renewable energy, nuclear resources, injection projects, anthropogenic resources and groundwater. It has a unique three- dimensional structure to describe environmental, social and economic viability (E-axis), technical feasibility and maturity (F-axis) and degree of confidence in the resource estimates (G-axis). The UNFC is fully aligned to holistic and sustainable resource management called for by the 2030 Agenda for Sustainable Development (2030 Agenda). UNFC can be used by governments for integrated energy planning, companies for developing business models and the investors in decision making. Internationally, all classification systems and their application continue to evolve to incorporate the latest technical understanding and usage and societal, government and regulatory expectations. The PRSG incorporates key elements from current global petroleum classification systems. Furthermore, it provides a forward-thinking approach to including aspects of integrity and ethics. It expands on the unique differentiator of the UNFC to integrate social and environmental issues in the project evaluation. Several case studies have been carried out (in China, Kuwait, Mexico, Russia, and Uganda) using UNFC. Specifically, PRSG assists in identifying critical social and environmental issues to support their resolution and development sustainably. These issues may be unique to the country, location and projects and mapped using a risk matrix. This may support the development of a road map to resolve potential impediments to project sanction. The release of the PRSG comes at a time of global economic volatility on a national and international level due to the ongoing impact and management of COVID-19, petroleum supply and demand uncertainty and competing national and international interests. Sustainable energy is not only required for industries but for all other social development. It is essential for private sector development, productive capacity building and expansion of trade. It has strong linkages to climate action, health, education, water, food security and woman empowerment. Moreover, enduring complex system considerations in balancing the energy trilemma of reliable supply, affordability, equity, and social and environmental responsibility remain. These overarching conditions make it even more essential to ensure projects are evaluated in a competent, ethical and transparent manner. While considering all the risks, it is also critical to reinforce the positive contribution a natural resource utilization project provides to society. Such an inquiry can focus on how the project contributes to the quality of life, environment, and the economy – the people, planet, and prosperity triad. Such an approach allows consistent, robust and sustainable investment decision making and energy policy development.

Full text

Abstract:

Abstract Elemental mercury and several mercury compounds occur naturally in geologic hydrocarbons including petroleum and gas condensates. Recent advances in analytical chemistry are assisting our understanding of the chemistry of mercury in petroleum and its fate in petrochemical processes. Analytical techniques now are capable of measuring the concentration of mercury and mercury compounds in most hydrocarbon matrices to better than 1 part in 1010. A recently developed model proposes that the mean amount of mercury in crude oil is no more than 10 ppb. The various chemical forms of mercury exhibit significantly different chemical and physical behavior and thus partition to fuels, products and effluents in a complex fashion. Speciation of compounds and accurate determination of species concentrations assists accounting for mercury in petrochemical processes and prediction of the magnitude of its occurrence in water and air emissions. From knowledge of the solubilities and partition factors of the mercury compounds in petroleum, one can predict concentrations in separations and distillations. The developing understanding of mercury concentrations in crude oil suggest that mercury discharges to the environment from petroleum are small as compared to those that originate from coal combustion. Although it is generally recognized that reductions in anthropomorphic mercury emissions are beneficial to reducing mercury in the global cycle, the strategies to achieve this goal should be carefully constructed and based on the known amounts of mercury in industrial emissions. Regulations, both existing and anticipated, are major factors driving the development of mercury sequestration strategies. Emissions of mercury from petroleum production and processing are regulated by water, sediment and air criteria that are based on estimates of mercury concentrations in liquid fuels that may be in error by at least an order of magnitude. Aside from environmental concerns, mercury also is problematic to both gas processors and refiners from the standpoint of operations. The issues relate to catalyst poisoning, health and safety and occasionally precipitation/condensation of mercury in cryogenic processes. Although mercury removal systems are applied to gas and gas liquids processing, such systems are ineffective for application to crude oil.

Full text

Abstract:

Abstract Adulteration of petroleum products with the resultant safety, health, environmental and economic impact is a challenge in Nigeria and many developing countries. While the commonly used techniques by regulatory agencies and some end-users for quality assurance of petroleum products are time-consuming and expensive. This study was therefore designed to develop a device for real-time detection of petroleum products adulteration. Samples of petrol, diesel and kerosene were collected; samples of water, naphtha, alcohol, pure and used lubricating oil, and High Pour Fuel Oil (HPFO) were collected and used as liquid contaminants while saw dust, ash and fine sand were used as solid particulates. At temperatures between 23-28°C (1°C interval), binary mixtures were prepared using the pure products with liquid contaminants (95:5, ..,5: 95 V/V) and with particulates (0, 2, 4, 6, 8,10 g). New mixing rules were developed for the SG and IFT of the binary liquid mixtures and compared with Kay mixing rule. Developed mathematical models of the physical-chemical properties were used to simulate a meter designed and constructed around a microcontroller with multiple input/output pins and a load cell sensor. The SG and IFT of the pure liquid and solid binary mixtures ranged from 0.810 to 1.020, 25.5 to 47.2 dynes/cm and 0.820 to 1.080 and 26.3 and 50.2 dynes/cm respectively. For products contaminated with solid particulates, SG varied between 0.860 and 0.990. The new mixing rule gave coefficient of 0.84 and 27.8 for SG and IFT compared with 0.83 and 25.6 of Kay's model. Adulteration of products was detected at 20-30% by volume and 10-20% by mass of contamination, and displayed RED for adulterated samples, GREEN for pure samples and numerical values of SG in digital form which were within ±0.01 % of actual measurements. A device for real-time detection of adulteration in petroleum products was developed which can be adapted to real-time evaluation of similar binary mixtures.

In International Petroleum Technology Conference. IPTC, 2021. http://dx.doi.org/10.2523/iptc-21297-ms.

Full text

Abstract:

Abstract Effective mudcake removal is essential to restore the optimal well productivity/injectivity after different drilling operations. Typically, this objective is achieved by using harsh chemical treatments such as hydrochloric acid (HCl), organic acids and oxidizers. However, these methods have been limited due to associated high corrosion rates, high operation cost, and un-even mudcake removal. This task becomes even more difficult and very challenging in horizontal/multilateral wells. Organic acids and acid precursors have been also used to clean long horizontal wells following drilling operations. However, in long multilateral horizontal wells, fluid placement is considered one of the main challenges with chemical mudcake removal treatments due to accessibility to each lateral and reaching its TD. Additionally, the use of these treatments has poor health, safety and environmental (HSE) footprints. This work provides a workflow and illustrates the use of an in-house designed zero-flaring flowback system to clean up recently drilled multilateral horizontal wells with water-based mud. The system consists of two upstream solid management systems, namely de-sander (cyclone), and sand catcher (filter). Downstream, the choke manifold, 4-phase separator, a downstream solid management equipment, and 3-phase separator are also included. Additionally, there is also a surge tank, as a backup flowback vessel to be used if needed to revive the well and offload any heavy fluids. This tank is used to initially help the well to gain the pressure momentum to naturally flow and offload heavy fluid present in production tubular. The cleanup campaign was successfully and safely completed for effective cleanup of more than 30 openhole horizontal multilateral wells without the use of any chemical treatments. The duration of cleanup operations was optimized using several techniques to effectively and efficiently remove existing mudcake. This paper provides the operational criteria to achieve effective and adequate mudcake removal for horizontal/multilateral wells and restore its optimal performance. Different design parameters and tailored flowback programs will be discussed, which led to effective drawdown pressure to reach optimized natural cleanup of each well. The well simulated flow model was also considered and used as input to design each well specific flowback program and minimize the risks of erosion, solids settlement in pipeline and downstream facilities. As a result, each well cleanup duration was reduced to an average of 1-2 day, while achieving the maximum potential production rate of each treated well.

Abstract:

Decades ago, oil spill has become a global issue. It effects not only environment but also economic life. Oil spills occur due to tanker disasters, wars, operation failures, during transportation, storage, use of oil and other accidents. Soil contaminated with petroleum effects human health, causes organic pollution of groundwater, which limits its use and decreases the agricultural productivity of the soil. Therefore, it is important to clean up oil spills as quickly as possible. Nowadays researchers are looking for new technologies that tackle three most important factors related with the oil spill clean-up: money, efficiency and time. The aim of this study was to evaluate the potential of bioremediation of petroleum hydrocarbons in oil-contaminated soil using silica nanocomposite. According to the findings, silica nanocomposite might increase microbial activity during biodegradation of petroleum hydrocarbons in soil because of the ability of nanoparticles to absorb water and keep moisture in soil thus creating a favourable environment for microorganisms. The study of biodegradation with the use of silica nanocomposite was carried out for a period of ten weeks in cooperation with the company Grunto Valymo Technologijos.

Abstract:

Snow and ice removal are important tasks during the winter season and large amounts of anti-icing and de-icing chemicals are used and there is a critical need to review and synthesize information from the literature to compare and contrast anti-icing and de-icing chemicals to understand their environmental impact and support decision making. The effectiveness, costs, and environmental impact of commonly used and alternative anti-icing and de-icing chemicals were reviewed in this study. Application of anti-icing and de-icing chemicals may increase ion concentrations in soils and change nitrogen cycle, soil pH, and trace metal concentrations, affect surface water and groundwater, and increase public health risks. Life cycle assessment was conducted to quantitively evaluate environmental impact of selected anti-icing and de-icing chemicals. A decision support tool on environmental impact was developed to evaluate environmental impact of anti-icing and de-icing chemicals in ten different environmental impact categories. The results showed the environmental life cycle assessment tool developed in this study can be used to compare multiple environment impacts to support decision making for winter operation chemicals.

Full text

Abstract:

The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and ecosystem health are dependent on processes occurring in the entire watershed as well as riparian and floodplain areas; therefore, they cannot be manipulated independently of this interrelationship. Land use activities—such as timber management, landfills, grazing, confined animal feeding operations, urbanization, stream channelization, removal of riparian vegetation and gravel, and mineral and metals mining—threaten stream quality. Accordingly, the framework for this aquatic monitoring is directed towards maintaining the ecological integrity of the streams in those parks. Invertebrates are an important tool for understanding and detecting changes in ecosystem integrity, and they can be used to reflect cumulative impacts that cannot otherwise be detected through traditional water quality monitoring. The broad diversity of invertebrate species occurring in aquatic systems similarly demonstrates a broad range of responses to different environmental stressors. Benthic invertebrates are sensitive to the wide variety of impacts that influence Ozark streams. Benthic invertebrate community structure can be quantified to reflect stream integrity in several ways, including the absence of pollution sensitive taxa, dominance by a particular taxon combined with low overall taxa richness, or appreciable shifts in community composition relative to reference condition. Furthermore, changes in the diversity and community structure of benthic invertebrates are relatively simple to communicate to resource managers and the public. To assess the natural and anthropo-genic processes influencing invertebrate communities, this protocol has been designed to incorporate the spatial relationship of benthic invertebrates with their local habitat including substrate size and embeddedness, and water quality parameters (temperature, dissolved oxygen, pH, specific conductance, and turbidity). Rigid quality control and quality assurance are used to ensure maximum data integrity. Detailed standard operating procedures (SOPs) and supporting information are associated with this protocol.
