Abstract:
Shale problems are the most common problems during the drilling process including sloughing shales and swelling clays. To minimize these problems, drilling fluid can be used to solve it. Wellbore stability analysis is critical to minimizing Non Productive Time and drilling costs in the East Baghdad Oilfield. Tanuma and Zubair formations are challenging formations due to shale-fluid chemical interaction. The present study aims to investigate the properties of shale samples and develop drilling muds through laboratory tests. The shale's physical attributes were analyzed using a stereomicroscope and scanning electron microscope to figure out its structures. Cation exchange capacity and capillary suction timer were also conducted to analyze the shale reactivity and select the shale inhibitors. Based on these tests, four drilling muds with unique additives were formulated, and their efficacy was verified using the linear swelling meter and the hot rolling experiments. The results showed a consistent and immediate interaction between the shale and various drilling fluids. A comparison was made between the first and second muds for Tanumah and Zubair formations, it was discovered that water-based muds1 exhibited greater swelling than water-based muds2, where swelling ratios for Tanuma shale units were 6.1% for water-based muds1 and 3% for water-based muds2. In comparison, for Zubair shale units, they were 3.01% and 1.53%, respectively. It is recommended to add 7% KCl to Tanuma mud and 3% KCl to Zubair mud as optimum additives with polypeptide hydration suppressants for inhibiting shale swelling and reducing its risk. This study's findings can contribute to the development of drilling muds that address shale instability concerns and thus minimize drilling expenditures.

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:
Abstract In this study, the impact of VG69 organophilic clay on the rheological properties of gasoil-based drilling muds (invert emulsions) was investigated. The flow curves of gasoil-based drilling muds as a function of the dose of VG69 organophilic clay were analyzed by the Casson model. The addition of VG69 organophilic clay with a quantity range between 0 and 5 g in gasoil-based drilling muds induces an increase in the yield stress and the viscosity at an infinite shear rate of drilling muds. It is also proven that the addition of VG69 organophilic clay leads to an increase in the viscoelastic and thixotropic properties of the drilling muds. The study of the stability of gasoil-based drilling muds by centrifugation showed that for a quantity of VG69 organophilic clay lower than 3 g, the stability of the drilling muds increases and for a quantity of VG69 organophilic clay higher than 3 g, their stability decreases. The results obtained showed that the addition of 3 g of VG69 organophilic clay to the gasoil-based drilling mud increased the yield stress by 230%, the viscosity at an infinite shear rate by 3.4% and it improved the mud stability by 70%.

The problems arising when drilling horizontal and gently sloping wells in the Valanginian deposits are considered. The analysis of technologies of drilling-in the Valanginian reservoirs by sideholes using water-base clay drilling muds and the aerated muds ensuring the high-quality exposure of productive layers is carried out. The most perspective for drilling side holes of wells in these conditions are hydrocarbon-base drilling muds which maintain the filtration properties of productive layers and reduce the accident rate of drilling operations.

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:
Invert muds are the most commonly used oil-based drilling muds. The oil to water phase ratio in invert drilling muds ranges from 65/35 up to 90/10, with the most common ones ranging from 70/30 to 80/20. At these oil to water phase ratios, the drilling mud is characterized with high stability and appropriate rheological and structural parameters allowing to adjust drilling mud density in a wide range. One of the disadvantages of invert muds is their cost (due to oil content) and environmental problems associated with waste and management of oily drill cuttings. Taking into account the properties of oil-based muds, the article presents laboratory tests aimed at developing the composition of an invert mud with a limited oil phase content and high internal phase ratio (HIPR). Drilling muds with an o/w ratio less or equal to 50/50 vary from conventional inversion muds in terms of their composition and properties. Due to the higher concentration of the dispersed inner phase, muds have reduced stability and high rheological and structural parameters. Maintaining the appropriate rheological and structural parameters of the drilling mud and its high stability is possible only through the use of appropriate chemicals adapted to the emulsion system with a specific oil to water phase ratio. In the drilling muds of this type it is also possible, due to the higher concentration of the internal phase, to partially adjust the density of the mud with the water phase, such as salt solutions, thus limiting the solids content (weighting agents) in the mud. The developed mud system should be more economical, have a reduced toxicity, while maintaining the operational advantages of invert mud. These types of muds can be used during the drilling of reactive shale formations, salt layers, gypsum and anhydrite layers, as well as for drilling productive horizons and for reconstruction works carried out in oil and gas wells.

Abstract:
This study investigated the performance of the biomass Eichhornia crassipes plant (ECP) as an additive in water-based drilling-mud. ECP is an invasive plant of fresh water ecosystems, so its use in drilling operations provides a low-cost, sustainable option that has off-site environmental benefits. Mechanical tests were conducted on ECP fibres to determine their stiffness under dried and water-wet conditions. Initial tensile tests on nylon fibre determined potential experimental artefacts with the experimental approach. The dried fibres had a water content of 8.163 wt. % (SE 0.636), whereas the wet fibres were 93.43 wt.% (SE 0.294). Water wet fibres had a lower modulus of elasticity than dried fibres and therefore, dried fibres have less tensile strength than wet fibres (Mean = 45.16 MPa; SE = 5.023; N = 41). Rheological properties of bentonite-based drilling muds amended with ECP at different concentrations were also studied. These muds were prepared by mixing ECP fragments at various concentrations (%w/w) with bentonite-water solutions and aged under ambient conditions. Mud viscosity gradually decreased with increasing shear rate, showing characteristic shear-thinning behaviour. Lost circulation of bentonite-water solutions mixed with ECP fragments were assessed with static filtration experiments. Slots and single perforated discs were designed to mimic fractures surrounding drilled boreholes. From a broad range of testing conditions, it was found that ECP fibres significantly decrease lost circulation by bridging fractures. An optimal concentration of 0.83 % by weight of ground plant stalks mixed with 6.28% bentonite in water improved rheology and filtration properties. A bridging gap model for a single fibre showed that ground stalk was less deflected than dried fibre when bridged an opening fissure. The findings of this research create an alternative to use ECP as lost circulation material in oil and gas drilling operations.

Abstract:
This project studied the production of barium sulphate nanoparticles through inhibition of crystal growth, during precipitation, by different surfactants. Barium sulphate is the pure form of the ore baryte, which due to its high density and softness, is the most commonly used additive used to increase the density of drilling fluids. A non-agglomerating, stable nano-scale dispersion of barium sulphate particles would have significant technical and commercial impact in the drilling fluids industry. This thesis tested the possibility of precipitating barium sulphate and restricting its crystal growth with inhibitors, creating nanoparticles. Six inhibitors were tested; dodecanoic acid, palmitic acid, stearic acid, adamantane carboxylic acid, methylnonanoic acid and a mixture of phosphate esters known commercially as Fazewet. Precipitated, inhibited barium sulphate was characterised using powder XRD, DRIFT FTIR and solid-state NMR (SSNMR). All inhibitors were shown to form single-phase, orthorhombic barium sulphate crystals proving that the inhibitors affect only the surfaces of precipitated crystals and do not enter the crystal lattice. FTIR allowed the relative adsorbed concentration of each inhibitor to be assessed. The results indicate that adsorbed inhibitor increases with increasing inhibitor concentrations but that their attachment is not proportional to the concentration. In most cases concentrations of 0.1mol l-1 of inhibitor were sufficient to saturate the crystal surface. SSNMR also agreed with this although the sample size was too small, due to equipment restrictions, to make definitive conclusions. Through the use of the Debye-Scherrer equation, the crystallite size was calculated and showed that at concentrations of 0.2mol l-1 all inhibitors other than palmitic acid produced nano-scale (< 100nm) crystallites. Further analysis showed that further reductions could be achieved through precipitation in an alkaline pH environment, with the application of mechanical shear and by using adding 50% v/v of ethanol. iv Laser diffraction particle size analysis showed that the dominant factor in reducing particle size distribution was inhibitor concentration. The volume-based PSD used by the laser diffraction system was considered to distort excessively the particle sizes present and so analysis switched to dynamic light scattering. DLS showed that dodecanoic acid, palmitic acid and stearic acid, despite forming nano-scale crystallites, could not produce a nano-scale dispersion of barium sulphate and as such were unsuitable for use in drilling fluids. Stable nano-scale dispersions were found to have been formed when inhibited with adamantane carboxylic acid, methylnonanoic acid and Fazewet. DLS also confirmed that dispersed particle size rather than simply crystallite size could be reduced with an alkaline pH and high mechanical shear. Concentration was still the dominant effect, however with the smallest particles sizes (ZAvg) being observed at concentrations of 0.6mol l-1. The particle sizes for the three modifiers were approaching that of the crystallite size, suggesting that some further reduction is possible, but large reductions are unlikely. All three inhibitors produced sub 100nm ZAvgs, with the smallest produced by methylnonanoic acid of 43nm. Spherical nanoparticles were observed through the use of ESEM and TEM. Due to equipment time restrictions only 0.2mol l-1 treatment levels could be examined, but ESEM showed apparent nanoparticle clusters, later confirmed using pixel count and SFDA methods. TEM analysis showed discrete particles as small as 3nm, indicating that the lower limit for achievable particle size may be lower than PSD measurements would suggest. The results indicate that adamantane carboxylic acid, methylnonanoic acid and Fazewet sufficiently inhibit crystal growth to be potential candidates for the production of barium sulphate nanoparticles. These three inhibitors produce a barium sulphate dispersion that is stable and nano-scale even after drying and redispersion.

Abstract:
The paper describes studies on the development of the new formulas of water-based drilling mud for drilling in clays and shales. The research were undertaken as a part of the OPTIDRILTEC project. First stage of the project included studies related to selection of ionic inhibitors of hydration. The tests of inorganic agents with various concentrations influence on technological parameters of the developed drilling muds was undertaken. The disintegration and linear swelling tests under influence of developed muds with different ionic inhibitors were conducted on the rock samples. Miocene shale was used as the model rocks. Within a framework of the project, it was conducted selection of the polymeric inhibitors of hydration. Subsequently, different polymers were tested for the influence on technological parameters of drilling muds as well as on disintegration and linear swelling of model rocks. Studies also consists of synthesis of short-chained cationic polymers (with primary amine groups in the side chains) and cationic-anionic polymers (with, apart amine groups, sulfonic amine groups). Synthesized polymers are characterized by low molecular masses (about 10.000 – 20.000 atomic mass unit) and small steric hindrance of side chains. The studies allowed development of new water-based mud formulas for drilling in clay rocks. Developed drilling muds are characterized by good technological parameters, resistance to temperature and to salts along with effective preservation against disintegration and swelling of clay rocks. Moreover, based on the research results it can be observed that synthesized cationic polymers are efficient inhibitors of clay rocks hydration. Newly developed drilling muds could be successfully applied in the oil and gas industry causing improved drilling conditions and decreased drilling costs.

Abstract The prediction of frictional pressure loss in many oil wells drillings is of the utmost importance. Most studies in this area concerned fluid flow in pipes and annulus in order to predict friction losses. However, studies on the tool-joint effect in frictional pressure estimations were limited to only a few experimental and theoretical studies on water-based power-law drilling muds. (Tool-joint is the part in which two drill strings connect where the annulus has a gradual decrease and increase, respectively). The tool-joint plays an important role in extending the drill pipe, and its effect on pressure losses cannot be ignored. As of today, drilling muds must have certain qualities such as providing formation integrity, transporting the cuttings from bit to surface, drill pipe lubrication and heat transfer, and low-pressure loss to perform as a qualified and effective drilling fluid. Therefore, drilling muds have become more complex and expensive, and the process of choosing appropriate drilling muds is of great importance. For this reason, oil-based viscoplastic drilling muds are being used in more drilling operations, but for these drilling muds, almost no studies were conducted to predict the effect of the tool-joints on flow behavior and pressure loss. In this paper, the behavior of fluid flows and frictional pressure losses in weld-on tool-joints of different grades according to the IADC standard manual was studied using CFD simulations. The simulations were conducted using a drilling fluid with viscoplastic properties, following the Herschel–Bulkley model of Non-Newtonian fluids. And the characteristics of fluid flows in these tool-joints under different thermal boundary conditions were studied. The results show that tool-joints significantly affect the frictional pressure loss in the annulus. We also provided an accurate pressure loss prediction for the flow of oil-based viscoplastic muds passing through the tool-joint geometry. Furthermore, assuming the thixotropic behavior using the Moore-Cheng model for the drilling mud, the results showed that the flow behavior does not differ significantly from the Herschel-Bulkley drilling fluid in the range of study.

Most studies in this area are concerned with fluid flow in pipes and annulus to predict friction losses. However, studies on the tool-joint effect in frictional pressure estimations were limited to only a few experimental and theoretical studies on water-based power-law and Herschel-Bulkley drilling muds. Tool-joint is the piece that connects two drill strings. The tool joint plays an important role in extending the drill pipe, and its effect on pressure losses cannot be ignored. In addition, the drilling muds must have certain qualities such as providing formation integrity, transporting the cuttings from bit to surface, drilling pipe lubrication and heat transfer, and low-pressure loss to perform as a qualified and effective drilling fluid. Therefore, drilling muds have become more complex and expensive. For this reason, oil-based viscoplastic drilling muds are being used in more drilling operations. These drilling muds almost always also show a thixotropic behavior which is the key point of this study. This paper studied the behavior of fluid flows and frictional pressure losses in weld-on tool-joints of different grades using CFD simulations. The simulations were conducted for a drilling fluid with viscoplastic (similar to the Herschel-Bulkley model) and thixotropic behavior. The characteristics of fluid flows in tool joints under different thermal boundary conditions were studied. Moreover, the different thixotropic behavior models and various thixotropic boundary conditions were compared to select the most fitting model. The results showed that tool joints significantly affect the frictional pressure loss in the annulus. The study also provided an accurate pressure loss prediction for the flow of oil-based viscoplastic muds passing through the tool-joint geometry. Furthermore, using the thixotropic behavior of the Moore-Cheng model for the drilling mud, the transient processes of the beginning of the drilling operations were investigated.
