Abstract:

In upstream petroleum industry, one of the major operations that can potentially impact the environment is drilling. A major component of the wastes generated during drilling are the rock cuttings and the drilling fluids. The drilling fluids can have different chemical composition and various additives. Spilled or improperly disposed drilling wastes have the potential to harm plants and animals, and it should be managed to minimize risk to human health and the environment. The increasing environmental legislation surrounding drilling operations has led to a rapid rise in drilling waste management spending by operators. Managing wastes to minimize their harm potential to health and environment is the international concern and requires efficient management of wastes to reduce the environmental impacts. The management and control of waste which develops from the strategy can also have the beneficial effect of reducing the number of health related issues.This paper presents the waste management including recognizing the waste sources and methods which are used to minimize the impaction to environment and human health from drilling waste. This paper also reviews the strategy of drilling waste management which could reduce the number of health related issues as well as environment pollution.

Abstract:

Drilling wells is an ecologically dangerous type of work accompanied by contamination of soil, subsurface and surface waters, pollution of open air with drilling and technological wastes. Throughout the drilling process, drilling waste is generated, such as drilling muds, return drilling muds, drilling waste water. The resulting waste is usually disposed of at landfills, which ensure minimal environmental impact. The use of drilling muds in other spheres is hindered by the complex composition of oily waste. Samples of liquids and solids in drilling wastes, picked at three locations, were subjects for analysis. The waste sample was analyzed for moisture content, organic substances, oil products, silicon, iron and other substances. Based on the studies performed, the authors propose additional introduction of substances possessing high sorption capacity into drilling mud to improve its properties. The most effective way should be using a sorbent capable of retaining organic and heavy metals. The resultant homogeneous soil-like mixture possesses the necessary and sufficient properties to be used as a mineral base for remediation after performing construction work in urban areas.

Abstract:

Significant amounts of produced water, spent drilling fluid, and drill cuttings, which differ in composition and characteristics in each drilling operation, are generated in the oil and gas industry. Moreover, the oil and gas industry faces many technological development challenges to guarantee a safe and clean environment and to meet strict environmental standards in the field of processing and disposal of drilling waste. Due to increasing application of nanomaterials in the oil and gas industry, drilling wastes may also contain nanometer-scale materials. It is therefore necessary to characterize drilling waste in terms of nanomaterial content and to optimize effective methods for their determination, including a key separation step. The purpose of this study is to select the appropriate method of separation and pre-concentration of silver nanoparticles (AgNPs) from drilling wastewater samples and to determine their size distribution along with the state of aggregation using single-particle inductively coupled plasma mass spectrometry (spICP-MS). Two AgNP separation methods were compared: centrifugation and cloud point extraction. The first known use of spICP-MS for drilling waste matrices following mentioned separation methods is presented.

Abstract:

A lot of drilling wastes with various content of oil products is formed annually during production of hydrocarbons in the result of accidents at the facilities of transportation and oil production, soil is polluted. So, main contaminants of the environment are drilling wastes such as drilling, drilling waste water, waste drilling fluid and places of their disposition - sludge pits. Total amount of the oil slurry annually formed at enterprises of the oil sector of Kazakhstan is about 100 thousand ton, and resources of these wastes are estimated in more than 40 mln. ton. The wastes are placed in special sludge pits equipped with watertight screen. However, in spite of the available modern technologies for arrangement of waterproof finish of the drilling waste disposal facilities, high level of soil pollution is still observed. As a rule, pollutions are related to violation of the requirements of the standards during construction and operation of sludge pits, products pipelines, tailing dumps, sludge collectors and temporary storages. Therefore it is necessary to build reliable storages for temporary placement of the formed wastes until their delivery for recovery or disposing, during operation of which there will be no migration of pollutants to the environment. It is suggested to use bentonitic mats as waterproof finish of such facilities - this is innovative by properties, multifunctional composite material, which is combination of textile materials with the layer of the natural self- recovering mineral component - bentonite.

Abstract:

Use of the soil as a receptor in the biodegradation of oily wastes is a widespread practice in the petroleum industry. Generated during drilling, these oily wastes may have intrinsic properties that inhibit microbial soil activity. CENPES, the Petrobrás research centre, has been studying disposal of these wastes. The results of physical and chemical analyses were used to select factors that may limit the application of these wastes in soil. High salinity and high baritine (BaSO4) contents, as well as substantial concentrations of some heavy metals, have been studied with the aim of ascertaining the maximum concentration of each at which degradation is still observed. Microbiological assays indicated maximum oil application rates varying from 1 to 20%, suggesting that each waste tested displays a different toxicity.

Abstract:

The existing computer technology is used to conduct an in-depth study and analysis of drilling waste treatment, and the results are analyzed by computer simulation optimization algorithms. Based on the system theory, we define the research system, combine the unique characteristics of the technological innovation mechanism of drilling waste treatment, and use the internal and external factors affecting the technological innovation dynamics of drilling waste treatment, such as drilling waste treatment capacity, from the current actual situation. On this basis, factor analysis is used to analyze the factors affecting technological innovation dynamics from both internal and external aspects of the system, establish a system model of technological innovation dynamics of drilling waste disposal, and give the initial values of the simulation model. This will reduce the pollution of the environment and enhance the competitiveness of enterprises. Drilling waste treatment technology is getting increased attention, but at this stage, there is no suitable technology innovation mechanism for drilling waste treatment. Through the simulation trend chart obtained by sensitivity analysis, the key factors in the system are found, and the innovation power mechanism of drilling waste treatment technology is constructed, which provides a basis for the formulation of enterprise technological innovation strategies and the development of technological innovation activities. Research on the dynamic mechanism of drilling waste treatment technology innovation explores a waste treatment mechanism suitable for the drilling industry, so as to promote the steady development of the drilling industry and at the same time provide theoretical support for the treatment of drilling engineering waste.

Abstract:

An important aspect of hydrocarbon drilling is the usage of drilling fluids, which remove drill cuttings and stabilize the wellbore to provide better filtration. To stabilize these properties, several additives are used in drilling fluids that provide satisfactory rheological and filtration properties. However, commonly used additives are environmentally hazardous; when drilling fluids are disposed after drilling operations, they are discarded with the drill cuttings and additives into water sources and causes unwanted pollution. Therefore, these additives should be substituted with additives that are environmental friendly and provide superior performance. In this regard, biodegradable additives are required for future research. This review investigates the role of various bio-wastes as potential additives to be used in water-based drilling fluids. Furthermore, utilization of these waste-derived nanomaterials is summarized for rheology and lubricity tests. Finally, sufficient rheological and filtration examinations were carried out on water-based drilling fluids to evaluate the effect of wastes as additives on the performance of drilling fluids.

Abstract:

The urgent character of modernization of the drilling waste management technologies from the standpoint of improving the environmental safety of territories during the oil and gas field development and operation was substantiated. The analysis of the existing drilling waste management methods was conducted and the classification of drilling waste ponds was presented. A layer-by-layer radiation-chemical analysis of drilling cuttings formed at the cluster drilling well in the Western Siberia (on the example of the Kustovoy field of "LUKOIL-Western Siberia", LLC) was conducted. A method for handling drilling waste, which is realized through the dosage batching of domestic-made reagents into a device for drill cuttings unloading from a drilling rig. The minimization of the secondary contamination threat is ensured by a more thorough mixing of the reagents with the waste, an increase in the contact time and the reaction completeness. The technology presented in the project allows preventing the formation of drilling waste, increasing the utilization depth and improving the technical requirements for the quality of the materials obtained.

Abstract:

Each year, the oil industry generates millions of barrels of wastes that need to be properly managed. For many years, most oil field wastes were disposed of at a significant cost. However, over the past decade, the industry has developed many processes and technologies to minimize the generation of wastes and to more safely and economically dispose of the waste that is generated. Many companies follow a three-tiered waste management approach. First, companies try to minimize waste generation when possible. Next, they try to find ways to reuse or recycle the wastes that are generated. Finally, the wastes that cannot be reused or recycled must be disposed of. Argonne National Laboratory (Argonne) has evaluated the feasibility of various oil field waste management technologies for the U.S. Department of Energy. This paper describes four of the technologies Argonne has reviewed. In the area of waste minimization, the industry has developed synthetic-based drilling muds (SBMs) that have the desired drilling properties of oil-based muds without the accompanying adverse environmental impacts. Use of SBMs avoids significant air pollution from work boats hauling offshore cuttings to shore for disposal and provides more efficient drilling than can be achieved with water-based muds. Downhole oil/water separators have been developed to separate produced water from oil at the bottom of wells. The produced water is directly injected to an underground formation without ever being lifted to the surface, thereby avoiding potential for groundwater or soil contamination. In the area of reuse/recycle, Argonne has worked with Southeastern Louisiana University and industry to develop a process to use treated drill cuttings to restore wetlands in coastal Louisiana. Finally, in an example of treatment and disposal, Argonne has conducted a series of four baseline studies to characterize the use of salt caverns for safe and economic disposal of oil field wastes.

Abstract:

Drilling of wells is accompanied by pollution of all environmental components with drilling and process waste. With drilling operations carried out, terrain and soil mass disturbance occur first. Waste generated during the drilling process includes drilling muds, return drilling muds, drilling wastewater. The contaminating ability of drilling waste is determined by the use of chemical reagents and components involved in the preparation and processing of drilling muds. The use of additives and reagents is necessary to make sure the solution displays certain properties that ensure effective well drilling. The resulting waste is usually disposed of at landfills or is buried at the site of formation in mud pits, ensuring minimal environmental impact. The use of drill muds in other spheres is hindered by the complex composition of oily waste.The composition of liquid and solid fractions of drilling muds from several deposits were studied in laboratory setting. Waste samples were analyzed for moisture content, organic substances, oil products and other substances. According to the results of the research, measures for improving the properties of drilling muds were developed and proposed. For this purpose, an introduction of high sorption substances to the waste is proposed.The most effective should be the use of a sorbent capable of retaining organic matters and heavy metals. The resulting homogeneous soil-like mixture can be used for land reclamation in the city areas and other settlements, when performing planning works at the initial and final stages of construction, as well as at landscaping residential areas.

Abstract:

Coalbed methane drilling can produce drilling fluid waste, and inappropriate treatment will influence the environment and subsequent operation. Because of the scattered coalbed methane well locations and cost reasons, domestic and foreign conventional oil and gas drilling fluid waste method cannot be copied. So the solidified method is more appropriate. Referencing the region of Lin Fen, by detecting five wells’ waste drilling fluid indoor, the indexes are pH, coloration, suspended matter, BOD5, COD, total chromium and hexavalent chromium. The drilling fluid index of waste-polymer is beyond the Grade-2 National Wastewater Discharge Standards, but the waste Fuzzy-Ball based drilling fluid reach the standards. It has been designed indoor that the formula of waste Fuzzy-Ball based drilling fluid solidified method’s which is mainly based on cement. The indexes of leaching solution are pH, coloration, suspended matter(99mg/l), BOD5(52.3mg/l), COD(117.4mg/l), total chromium(0.32mg/l), hexavalent chromium(0.13mg/l) and the leaching solution can reach the Grade-2 National Wastewater Discharge Standards. Solidification mud can achieve without large appliance and can deal with 200m3 waste Fuzzy-Ball based drilling fluid of JU2-H well in 10 days, its indexes of leaching solution can reach the Grade-2 National Sewage Discharge Standards. The strengths must be sure for the later vehicle transporting and the cultivation after land fill. Using Fuzzy-Ball based drilling fluid when drill can ensure the source controlling of waste drilling fluid pollution. At the same time, it can cost lower and operate easier.

It is established that the most accessible way of isolation of toxic wastes formed during drilling, development, exploitation and treatment of oil and gas wells products is to dispose them directly in the earth's slime dumps on the territory of the drilling site or beyond. The dump’s pit must have a watertight protective diaphragm, which is durable and resistant to the aggressive effects of toxic waste drilling and exploitation of oil and gas wells. The chemical composition of the borehole mud is determined. The results of experimental laboratory researches of borehole mud aggressive components influence on the physical and mechanical watertight diaphragm characteristics are given. The geotechnical parameters of soil-cement were analyzed with the aim of its application for the arrangement of toxic waste watertight dump’s diaphragm.

Abstract:

Abstract The oil containing drilling waste is a worldwide environmental problem associated with oil and gas exploration. In Poland, the problem of the drilling waste has become important since starting of shale gas exploration. The results of thermal treatment of drilling waste from shale gas exploration are presented. It has been shown that organic content vaporized completely at temperature up to 500 °C. The main problem is high content of chloride, sulfate, sodium, potassium, magnesium in the waste and its water leachate. Toxicity tests confirmed that high salinity of the samples pose important risk for environment. Due to the high content of barium, the drilling waste may be utilized in production of cement with high chemical and heat resistance and opaque to X-ray. Thermal treatment process is a viable option for remediation of the drilling waste; however, the product of the process needs further treatment in order to remove its high salinity.

Abstract This article reports a quick-setting agent named AS-G1. In the current offshore oil exploitation, there are usually wastes mixed with the drilling fluid, completion fluid, cement slurry, etc. To protect the marine environment, offshore construction workers need to weakly solidify these wastes so that they can be transported to land for disposal. The accelerating agent can reduce the fluidity of offshore cementing wastes and achieve the effect of solidifying wastes. Compare the time for the three cement slurries to lose fluidity with the addition of accelerating agents. Evaluate the setting time of cement slurry under the action of the accelerating agent after adding two drilling fluids. The solidification effect of this kind of accelerating agent on cementing waste is verified. It can be applied to waste treatment in oil fields.

Abstract:

The most used flocculants in treatment of waste drilling water are PAM flocculants. But its polymeric monomer often has toxicity. Gelatin is a non-toxic, amphipathic natural macromolecule. The flocculants prepared by gelatin and its application in waste drilling water has not been reported. In the experiment, gelatin was extracted from chrome shavings. Sulfate, citric acid and trypsinase were chosen to hydrolyze gelatin and then collagen solution was obtain. Then NaNO2 was added to seal amino of the collagen molecules. The flocculation effects of collagen solution before and after sealing amino on waste drilling fluid was estimated by its CODcr removal rate and the concentration of suspended solids. The results indicated that after sealing amino, the flocculation effect on waste drilling fluid decreased obviously. And when trypsinase was used as hydrolytic agent, the treatment effect on waste drilling fluid was better. The optimal hydrolysis condition was: pH was 7~7.5, temperature was 37°C, reaction time was 3h and the dosage of trypsinase was 1.5% of the gelatin. Under this condition, the CODcr removal rate was 46.7% and the suspended solid content of waste drilling fluid decreased from 2607mg/L to 730mg/L.

Oil-based drilling fluid is used more and more in the field of oil and gas exploration. However, because of unrecyclable treating agent and hard treatment conditions, the traditional treating technologies of waste oil-based drilling fluid have some defects, such as waste of resource, bulky equipment, complex treatment processes, and low oil recovery rate. In this work, switchable deoiling agent (SDA), as a novel surfactant for treatment of waste oil-based drilling fluid, was synthesized by amine, formic acid, and formaldehyde solution. With this agent, the waste oil-based drilling fluid can be treated without complex process and expensive equipment. Furthermore, the agent used in the treatment can be recycled, which reduces waste of resource and energy. The switch performance, deoiling performance, structural characterization, and mechanisms of action are studied. The experimental results show that the oil content of the recycled oil is higher than 96% and more than 93% oil in waste oil-based drilling fluid can be recycled. The oil content of the solid residues of deoiling is less than 3%.

Abstract:

ABSTRACTThis study aimed to evaluate the effects of the application of two types of oil drilling wastes on the development and absorption of barium (Ba) and sodium (Na) by sunflower plants. The waste materials were generated during the drilling of the 7-MGP-98D-BA oil well, located in the state of Bahia, Brazil. The treatments consisted of: Control – without Ba application, comprising only its natural levels in the soil; Corrected control – with fertilization and without wastes; and the Ba doses of 300, 3000 and 6000 mg kg-1, which were equivalent to the applications of 16.6, 165.9 and 331.8 Mg ha-1 of waste from the dryer, and 2.6, 25.7 and 51.3 Mg ha-1 of waste from the centrifugal. Plants cultivated using the first dose of dryer waste and the second dose of centrifugal waste showed growth and dry matter accumulation equal to those of plants under ideal conditions of cultivation (corrected control). The highest doses of dryer and centrifugal wastes affected the development of the plants. The absorption of Ba by sunflower plants was not affected by the increase in the doses. Na proved to be the most critical element present in the residues, interfering with sunflower development.

Abstract:

A large amount of drilling fluid waste is produced as effluents during exploration and production of oil and gas. Such effluents need to be treated before their final disposal. Efficient coagulation/flocculation can reduce the total amount of disposed effluent, and both coagulation by inorganic salts and flocculation by synthetic flocculants are found to be very effective. The graft-copolymers-based flocculants were prepared using a potassium persulfate initiator solution made by grafting copolymerisation of polyacrylamide onto polysaccharide backbones (starch, guar gum and amylose) in our laboratory. The synthesised graft copolymers have been characterised using various instrumental methods of analysis. The effects of various synthetic flocculants and their concentrations have been studied in combination with the coagulants on coagulation/flocculation of bentonite-based drilling fluid waste have been studied. The effects of coagulant/flocculant dosage, electrolyte concentration and pH on the degree of flocculation of bentonite-based drilling fluid waste was investigated. It was observed that the increase in coagulant/flocculant dosage reduces the residual turbidity and improves the settling rate of the drilling fluid waste. At higher pH conditions, drilling fluid waste dispersions are highly flocculated and have high settling rates and low supernatant turbidity. The combined effect of salt concentration and coagulant/flocculant dosage improves the overall flocculation efficiency of the system.

Abstract:

Curing research on waste oil-base shale gas drilling mud was performed for optimal additions matching. Destabilizing experiments on waste drilling mud demonstrated that Aluminum potassium sulfate (KAl(SO4)2) played a best role of destabilizing effects when compared with FeCl3 and AlCl3 based on demulsification mechanism about oil-in-water type. Aluminum potassium sulfate emerged an impact influence on curing effects simultaneously when compared to sodium silicate, alumina, lime and complex Portland cement. Orthogonal test on curing waste drilling mud revealed that the optimal operation conditions of handling waste drilling mud was 4% aluminum potassium sulfate, 4% sodium silicate, 4% alumina, 4% lime and 16% complex Portland cement. Under this condition, unconfined compressive strength of the curing product was 1.80MPa, and lead leaching concentration cannot be detected after 7d maintenance. The curing mechanism was mainly the encapsulation of C3S and solid waste contaminated by mineral oil can be efficiency treated after breaking the interface of oil-in-water type.

Abstract:

The drilling fluid is essential for drilling operations in the oil and gas industry. It is a complex mixture of organic and inorganic materials blended together to achieve desired multi-functions. There are several types of drilling fluid commonly in use, oil-based drilling fluid considered the most hazardous and harmful for the surrounding environment because of contaminated waste produced, normally consisting of diesel, oil, asphalt, polymers, crude oil and surfactants. Produced drill cuttings are contaminated by hydrocarbons, and other chemical additives. The produced drill cuttings are hazardous for environment as they contain polycyclic aromatic hydrocarbons and undesirable heavy metals. Presently, various oil and gas operator companies in Yemen and other parts of the world dispose the drilling wastes in excavated pits or landfill sites. It is not acceptable to deal with such hazardous substances in this manner. Other operator companies use thermal desorption technique as a separation method. This method still has many disadvantages. Therefore, it is vital to search for sufficient and efficient technologies and processes to treat oil-based drilling wastes as the existing methods in use cannot be considered as a viable solution to eliminate the environmental damaged caused by contaminated drill cuttings. This paper review three existing experimental methods of extraction that have significant total organic carbon removal efficiency and highlighted factors that effect on the extraction efficiency. They are; supercritical water oxidation, superheated steam extraction, and supercritical carbon dioxide extraction. The stated experimental studies -have shown promising results and efficiency in extraction of carbon content and are considered environmentally friendly.

Abstract:

Abstract Adsorbent is an important waste water-based drilling fluid treatment agent, which can adsorb and settle heavy metal ions, high polymer organics, and other soluble harmful substances in the waste drilling fluid. Traditional adsorbents such as polyaluminum chloride and polyacrylamide will produce other metal ions or toxic monomers after hydrolysis, which cannot fully meet the requirements of safety and environmental protection. Therefore, a new environmentally friendly waste water-based drilling fluid adsorbent, named RH-β-CD, was prepared by the Wilson etherification reaction, which was initiated by epichlorohydrin and ceric ammonium nitrate, and successfully grafted rhamnolipid and amine strong adsorption groups onto β-cyclodextrin. The adsorption effect and environmental protection performance of RH-β-CD on the organic matter and chromium ion in waste sulfonated water-based drilling fluid were evaluated and compared with commonly used adsorbents such as activated carbon, PAM, and polyaluminum chloride. The results show that RH-β-CD can effectively adsorb the organic matter in the filtrate of waste water-based drilling fluids, reduce its chemical oxygen consumption, and reduce the concentration of heavy metal ions in the filtrate. The effect is better than PAM, activated carbon, and polyaluminum chloride, with the BOD5/CODcr >20% and EC50 >1,000,000 mg·L−1, which is environmentally friendly.

Abstract:

Abstract Oil and gas producing enterprises at all stages of the life cycle have a negative impact on the components of the natural environment: atmosphere, soil, surface water bodies and groundwater. One of the serious environmental problems is the formation of drilling sludge during the construction of wells for oil and gas production. Some enterprises have debts on illiquid sludge barns. One of the reasons for this state of affairs is the shortcomings in the calculation of the actual volumes of sludge formed during drilling. The analysis of the existing methods for calculating drilling waste, literature sources and available materials for calculating the volume of drilling mud has revealed certain inaccuracies (errors) in calculating the volume of drilling mud and some unaccounted factors associated with the operation of drilling tools. A computational experiment was carried out and, using the example of one of the oil and gas producing enterprises, a comparison of the volumes of drilling sludge was made, taking into account possible errors, and a discrepancy of 181 m3 of drilling sludge per well was revealed. The elimination of errors in the calculation of waste generation standards and limits on their placement during the construction of wells will allow to adjust the volume of drilling waste generated and prevent the occurrence of possible environmental problems at the sites of well construction.

Abstract:

Drilling fluid represents the most important fluid that must fulfill numerous important assignments during drilling operations. Many commercially available additives for water-based drilling fluid fall into the category of non-degradable and environmentally hazardous materials. Significant development in this area can be made by using biodegradable materials as additives in drilling fluids. The objective of this study was to determine whether mandarin peel powder particle size affects the properties of the drilling fluid. In this paper, mandarin peel was used in the form of a dry powder divided into particle sizes smaller than 0.1 mm, and between 0.1 mm and 0.16 mm. Mandarin peel powder was added to a water-based drilling fluid in four different concentrations (0.5, 1, 1.5, and 2% by volume of water). By increasing the mandarin peel powder concentration, the API filtration reduced up to 42%, PPT filtration significantly decreased up to 61.54%, while the rheological parameters generally increased but remained within acceptable limits. It is determined that the optimal concentration of mandarin peel powder is up to 1.5% by volume of water.

Abstract:

Oil and gas exploration and production activities generate large amounts of waste material, especially during well drilling and completion activities. Waste material from drilling activities to the greatest extent consists of drilled cuttings and used drilling mud with a smaller portion of other materials (wastewater, produced hydrocarbons during well testing, spent stimulation fluid, etc.). Nowadays, growing concerns for environmental protections and new strict regulations encourage companies to improve methods for the reduction of waste material, as well as improve existing and develop new waste disposal methods that are more environmentally friendly and safer from the aspect of human health. The main advantages of the waste injection method into suitable deep geological formations over other waste disposal methods (biodegradation, thermal treatment, etc.) are minimizing potentially harmful impacts on groundwater, reducing the required surface area for waste disposal, reducing the negative impact on the air and long-term risks for the entire environment. This paper gives a comprehensive overview of the underground waste injection technology, criteria for the selection of the injection zone and methods required for process monitoring, as well as a comprehensive literature overview of significant past or ongoing projects from all over the world.

Abstract:

Steelmaking is an energy-intensive process that generates considerable amounts of by-products and wastes, which often pose major environmental and economic challenges to the steel-making industry. One of these by-products is steel dust that is produced during the separation of impurities in the smelting and refining of metals in steel-making furnaces. In this study, electric arc furnace (EAF) dust has been evaluated as a potential, low-cost additive to increase the viscosity and weight of drilling muds. Currently, the cost of drilling operations typically accounts for 50 to 80% of the exploration costs and about 30 to 80% of the subsequent field development costs. Utilization of steelmaking waste in drilling fluids formulations is aimed to produce new and optimized water-based drilling formulations, which is expected to reduce the amount of bentonite and other viscosifier additives used in the drilling formulations. The results showed that in a typical water-based drilling fluid of 8.6 ppg (1030.51 kg/m3), the amount of standard drilling grade bentonite could be reduced by 30 wt.% with the addition of the proposed new additive to complete the required mud weight. The mixture proved to be stable with no phase separation.
