Methane Adsorption and Desorption on Continental Shaly Matrix: Implications for Shale Gas Condensate Exploration and Production.

Shale gas condensate is a burgeoning unconventional resource with adsorbed methane (CH4) as its dominant component. Successful evaluation of marine shale gas gives limited insights into the evaluation of continental shale gas condensate due to their different occurrence patterns of organic matter and inorganic minerals and resultant contributions to pore development and CH4 ad-/desorption capability. To address this issue, we employed an advanced low-temperature oxygen plasma (LTOP) technology to extract organic matter from the continental shaly matrix. Results showed that the continental shaly matrix contains more clay minerals and less quartz, and develops fewer pores and fractures than typical marine shaly matrix. The organic matter-hosted pores instead of inorganic mineral-hosted pores are more weighted to the pore development in the continental shaly matrix. However, the inorganic minerals of the continental shaly matrix contribute more to CH4 adsorption capability than the organic matter, which could be attributed to the higher density of available adsorption sites toward CH4. Besides, the CH4 ad-/desorption hysteresis is more pronounced for the organic matter-free continental shaly matrix than the raw continental shaly matrix, which is attributed to the remarkable CH4 adsorption-induced clay mineral swelling. Overall, the effects of inorganic minerals in CH4 adsorption and desorption, particularly clay minerals, are crucial for continental shale gas condensate exploration and production.

Application of machine learning to decline curve analysis (DCA) for gas-condensate production wells with complex production history due to add-on perforation of new reservoirs

For every oil and gas operator, DCA plays an essential role since it provides crucial information for production planning and reserves estimation. DCA is the analysis of the decline in production rate or pressure over time, which can be done by fitting a curve through production or pressure historical data points and making a forecast for the well based on the assumption that the same declining trend will continue in the future. However, the conventional DCA method has been shown to have some limitations. On the other hand, machine learning has been vigorously and extensively researched in the last decade; its applications can be found in every aspect of life as well as in the oil and gas industry. Therefore, it is the ideal time to study the application of machine learning to DCA, to complement this important analysis. In this case study, machine learning was used to predict the decline of wellhead pressure, thereby determining well life as well as estimating reserves. The method was applied to 2 wells with very complex production histories due to add-on perforation of new reservoirs. The prediction was verified to have high reliability by comparison with dynamic modeling results.

"ANALYSIS OF WELL COMPLETION COMPLICATIONS AND THEIR ELIMINATION IN THE KARACHAGANAK FIELD"

"By examining well completion issues, the paper will demonstrate the importance and beneficial effects of using multi-stage selective acid treatment technology to regulate reservoir development. The original goals for the Karachaganak field were a review of the field’s operating conditions, the building of the first plant for producing gas and gas condensate, and the design of the production circuit. After the separation of products contract was signed, new goals were added, such as accelerating oil well commissioning, increasing gas condensate production over the long term, and pumping at least 40 % of the gas back into the layer. Numerous well completion techniques have been improved thanks to technical developments, including applying tubing while sealing metal-to-metal threaded connections, omitting the use of a circulation valve above the packer, and utilizing a downhole shut-off valve. The field development project’s Phase 2M got under way in 2003. An innovative well completion technique was used in the Karachaganak field, which used acid fracturing in an open hole with packers and circulation valves to separate the intervals. In 8 horizontal wells, the multistage stimulation approach has proved effective, saving both time and money. In one of the wells, selective stimulation was made achievable by an acid treatment plan that met zonal injectivity standards. Increased well productivity, flow distribution, gas, water, and drawdown control have all been benefited by multistage selective acid stimulation. "

Участие химических реагентов в изменении физико-химических свойств мазута

Quality of process flows and commercial oil products deteriorates due to developing the deposits, which reduces the efficiency of heat and mass transfer and, accordingly, the clarity of rectification, resulting in changes in the component and fractional composition of the processed raw materials. There has been studied the influence of different chemical reagents introduced at the stages of production, treatment and processing of gas condensate and oil on the change in the physicochemical properties of the resulting dark oil products, which are responsible for deposit formation in the field and plant equipment during further processing or storage. The results of experimental studies are presented. Physicochemical properties of fuel oil are shown to be affected not only by the properties of the hydrocarbon feedstock, but also by the composition and concentration of chemical reagents introduced at different stages of production, field preparation and transportation. In the course of the experiment it has been stated that, depending on the concentration of the reagent and its main active substance, the structure of the oil system changes followed by the kinematic viscosity and pour point of the raw material. It has been found that chemical reagents improving the specified characteristics of oil products are able to worsen others.

Integrating computational fluid dynamic, artificial intelligence techniques, and pore network modeling to predict relative permeability of gas condensate

The formation of gas condensate near the wellbore affects the gas liquid two-phase flow between the pores. It may occur in the path between two pores depending on the thermodynamic conditions of the single-phase gas flow, two-phase gas liquid annular flow or the closed path of condensate in the throat. To model the behavior of gas condensate in a network of pores, relative permeability and naturally pressure drop should be calculated. This study obtained the flow characteristics (pressure drop) between the pores at different physical and geometric conditions using computational fluid dynamics (CFD). CFD is time-consuming, so its results were transferred to an artificial neural network (ANN) model and the ANN model was trained. The CFD was replaced with the ANN model for calculating the pressure drop. In addition, instead of utilizing empirical correlations to compute the accurate value of condensate formed in throats' corners at every time step, the flash calculation using Esmaeilzadeh–Roshanfekr equation of state was performed, and closed throats were specified. This accurately estimates gas and condensate distribution in the pore network. Furthermore, the value of condensate that transferred to the adjacent throats was computed using Poiseuille's law. The results showed that the proposed ANN-based proxy model could promote the calculation speed in gas condensate simulation, considering the dynamic change of relative permeability curves as a function of gas condensate saturation. Also, it was found that the relative permeability obtained by the proposed model is in good agreement with the experimental data. By entering the fractures pattern in the network model and predicting the relative permeability of gas and condensate by the proposed method, the role of fractures in gas condensate production in such reservoirs could be predicted. Dynamic changes due to the relative permeability of gas and condensate as a function of saturation can be entered into the reservoir simulation to optimize inertia and positive coupling phenomena to maximized condensate production in gas condensate reservoir.

Prevention and removal of hydrate formation at the Amangeldy gas field

Currently, antihydrate inhibitors such as methanol and diethylene glycol are used to reduce the temperature of hydrate formation during the transportation of gas and gas condensate in in-field gas pipelines, i.e. in plumes. If the desired results are not obtained during the production of gas and gas condensate without the use of anti-hydrate inhibitors (during operation, a certain volume of produced gases and condensate is blown onto a flare or a bleeder stack), this may, in turn, lead to a shutdown of the well, as a result of which the volume of production will also decrease.

Environmental Impact Assessment of Asaluyeh Gas Refinery Products Based on Blue Water Footprint Measurement

Background: The current state of water resources in Iran and the process of governing them in recent years indicate the importance of demand management and water consumption reduction in all fields, such as agriculture, industry, service, and domestic. Suppose water consumption reduction or demand management are not applied, or accurate knowledge of freshwater consumption assessment is not acquired in various environmental fields due to dwindling water resources. In that case, it will be difficult or uneconomical for industrial production to provide fresh water in the near future. Furthermore, the adverse environmental impact of freshwater consumption on various industries and its recurrence will inevitably cause an imbalance in the ecosystem and result in many problems. Methods: This study analyzed eight parameters of environmental impact assessment through Life Cycle Assessment (LCA) after apprising blue water footprints in the production of methane, ethane, propane, butane, gas condensate, and sulfur at the processing units of Asalouyeh Gas Refinery by taking the essential items into account (consumed blue water, electricity consumption, and consumption of common and widely used chemicals in the production process). Results: The results of the environmental impact assessment of producing each ton of the aforementioned products are as follows: Environmental impact of acidification: The greatest impact was left by gas condensate, which produced 5.086 kg of SO2, whereas the smallest impact was made by sulfur production with 0.813 kg. Environmental impact of eutrophication: The greatest impact with 0.476 kg of PO4-- was left by methane production, whereas the smallest impact was made by sulfur production with 0.147kg of PO4--. Environmental impact of global warming: The greatest impact was made by gas condensate, which produced 1140.161 kg of CO2, whereas the smallest impact was made by sulfur production, which produced 182.425 kg. Environmental impact of photochemical oxidation: The greatest impact was left by gas condensate, which produced 4.313kg of NMVOC, whereas the smallest impact was made by sulfur production, which produced 0.69 kg of NMVOC. Environmental impact of abiotic element depletion: This parameter is considered because of the very small quantities of software in all gas refinery products. Environmental impact of fossil fuel depletion: The greatest impact was left by gas condensate, which produced 85137.066 kg of MJ, whereas the smallest impact was made by sulfur production, which produced 13621.928 kg of MJ. Environmental impact of water scarcity: The greatest impact was left by gas condensate with 15906.544 m3, whereas the smallest impact was left by sulfur production with 2545.046 m3. Environmental impact of ozone layer depletion: The greatest impact was made by sulfur, which produced 8.121 kg of CFC11, whereas the smallest environmental impact, with a large difference from sulfur and a small difference in numerical values, was left by other refinery products. Conclusions: The results of measuring the blue water footprints in the production process revealed that gas condensate consumed the largest amount of water and sulfur consumed the smallest.

Treatment of methanol-containing wastewater at gas condensate production

The purpose of the study was to assess the impact of industrial wastewater on the concentration of methanol in the considered section of the Ob River basin, present proposals for the implementation of a new treatment system and analyse the implementation results. On the basis of the results of the analysis of the known methods for reducing the concentration of methanol in water, a new technological scheme for post-treatment of effluents using biological treatment with methylotrophic Methylomonas methanica Dg bacteria was proposed. The calculation of the dilution of treated wastewater using the “NDS Ecolog” program was carried out on the basis of the detailed calculation method of Karaushev, the results of which showed a decrease in the concentration of methanol in the control section to 0.0954 mg∙dm –3 (permissible concentration is 0.1 mg∙dm –3). During the period of the flood of the Glukhaya channel, it ceases to be a separate water body and, in fact, becomes part of the flood channel of the Ob River. Certain parts of the flooded areas, due to elevation changes, communicate with the channel only during a short period of time when the water level rises, i.e. 3–5 weeks during the flood period, and in fact remain isolated reservoirs for the rest of the time, potentially acting as zones of accumulation and concentration of pollutants.

Tuning the natural gas dew point by Joule-Thomson and Mechanical Refrigeration processes: A comparative energy and exergy analysis

In this study, to adjust the dew point of natural gas, two methods of Joule-Thomson and mechanical refrigeration have been analyzed in terms of technical, energy and exergy. The basis of design was a natural gas feed with an intensity of 1743 kgmole/h. The initial dew point of the feed before processing was equal to 9.65 °C. Comparison of the results showed that the mechanical refrigeration method had much better performance and the energy efficiency in this system was 99.84%, while this value was 97.8% for the Joule-Thomson method. Furthermore, the intensity of gas condensate production, as one of the products of dew point adjustment unit, for mechanical refrigeration that uses propane refrigerant for natural gas refrigeration was estimated as 1842 barrels/day. This value exhibited an increase of 185% compared to Joule-Thomson method. The dew points of produced gas through Joule-Thomson and Mechanical refrigeration processes were −8.4 and −24.91 °C, respectively. It implies that the quality of hydrocarbons dew point in the produced gas was much lower for Joule-Thomson unit compared to mechanical refrigeration. However, in terms of exergy analysis, the mechanical refrigeration method had an efficiency of 88.69%, while the exergy destruction rate for this method was 15.78% less than the Joule-Thomson process.

Computational and experimental studies of unstable isothermal filtration of methane–n-pentane gas-condensate mixture

During the operation of gas-condensate fields, reservoir pressure gradually decreases. When the pressure drops below the dew point, a retrograde fluid with low mobility is formed, which significantly reduces the well flow rate. Under certain conditions (pressure drop, yield point of the liquid phase, and absolute permeability of the reservoir), unstable filtration modes may occur, including those that block fluid flow. Determination of these conditions is necessary for planning a gas-condensate production strategy and developing methods for influencing the reservoir system to increase the flow rate of valuable hydrocarbon feedstock.This paper presents the results of computational and experimental studies of the isothermal filtration process of a model methane–n-pentane mixture in a porous medium. The studies were carried out on a linear bulk reservoir model at supercritical inlet pressures and variations in the composition of the supplied mixture and pressure at the model outlet. As a result of numerical and laboratory experiments, it was shown that there is a region of parameters (composition of the mixture, pressure drop, and yield point of the liquid phase) in which flow modes can be unstable, including those with periodic blocking of the fluid flow. The conditions for the appearance of unstable flow modes are discussed.

Virtual Multiphase Flowmetering Using Adaptive Neuro-Fuzzy Inference System (ANFIS): A Case Study of Hai Thach-Moc Tinh Field, Offshore Vietnam

Summary For any oil and gas company, well-testing and performance-monitoring programs are expensive because of the cost of equipment and personnel. In addition, it may not be possible to obtain all of the necessary data for a reservoir for a period of time because of production demand constraints or changes in surface process conditions. To overcome these challenges, there are many studies on the implementation and value of virtual flowmetering (VFM) for real-time well performance prediction without any need for a comprehensive well-testing program. This paper presents the VFM model using an adaptive neuro-fuzzy inference system (ANFIS) at Hai Thach-Moc Tinh (HT-MT) gas-condensate field, offshore Vietnam. The ANFIS prediction model can tune all its membership functions (MFs) and consequent parameters to formulate the given inputs to the desired output with minimum error. In addition, ANFIS is a successful technique used to process large amounts of complex time series data and multiple nonlinear inputs-outputs (Salleh et al. 2017), thereby enhancing predictability. The authors have built ANFIS models combined with large data sets, data smoothing, and k-fold cross-validation methods based on the actual historical surface parameters such as choke valve opening, surface pressure, temperature, the inlet pressure of the gas processing system, etc. The prediction results indicate that the local regression “loess” data smoothing method reduces the processing time and gives both clustering algorithms the best results among the different data preprocessing techniques [highest value of R and lowest value of mean squared error (MSE), error mean, and error standard deviation]. The k-fold cross-validation technique demonstrates the capability to avoid the overfitting phenomenon and enhance prediction accuracy for the ANFIS subtractive clustering model. The fuzzy C-mean (FCM) model in the present study can predict the gas condensate production with the smallest root MSE (RMSE) of 0.0645 and 0.0733; the highest coefficient of determination (R2) of 0.9482 and 0.9337; and the highest variance account of 0.9482 and 0.9334 for training and testing data, respectively. Applied at the HT-MT field, the model allows the rate estimation of the gas and condensate production and facilitates the virtual flowmeter workflow using the ANFIS model.

Investigation of gas gathering pipelines operation efficiency and selection of improvement methods

Purpose: The article implies theoretical and experimental studies of the liquid pollution accumulations impact on the efficiency of gathering gas pipelines operation at the Yuliivskyi oil and gas condensate production facility (OGCPF). Research of efficiency of gas pipelines cleaning by various methods. Design/methodology/approach: The research methodology consists of determining the hydraulic efficiency of gathering gas pipelines before and after cleaning of their internal cavity by different methods and comparing the obtained results, which allows to objectively evaluate the efficiency of any cleaning method. CFD simulation of gas-dynamic processes in low sections of gas pipelines with liquid contaminants. Findings: Experimental studies of cleaning efficiency in the inner cavity of the gas gathering pipelines of the Yuliivskyi OGCPF by various methods, including: supply of surfactant solution, creating a high-speed gas flow, use of foam pistons were performed. It was established that cleaning the inner cavity of gas gathering pipelines by supplying a surfactant solution leads to an increase in the coefficient of hydraulic efficiency by 2%-4.5%, creating a high-speed gas flow by 4%-7%, and under certain conditions by 8%-10 % and more. However, for two gas pipelines the use of foam pistons allowed to increase the coefficient of hydraulic efficiency from 5.7 % to 10.5 % with a multiplicity of foam from 50 to 90. be recommended for other deposits.The results of CFD simulation showed that the accumulation of liquid contaminants in the lowered sections of gas pipelines affects gas-dynamic processes and leads to pressure losses above the values provided by the technological regime. With the increase in liquid contaminants volume the pressure losses occur. Moreover, with a small amount of contamination (up to 0.006 m3), liquid contaminants do not have a significant effect on pressure loss. If the contaminants volume in the lowered section of the pipeline is greater than the specified value, the pressure loss increases by parabolic dependence. The increase in mass flow leads to an increase in the value of pressure loss at the site of liquid contamination. Moreover, the greater the mass flow, the greater the impact of its changes on the pressure loss. The CFD simulation performed made it possible not only to determine the patterns of pressure loss in places of liquid contaminants accumulation in the inner cavity of gas pipelines, but also to understand the gas-dynamic processes in such places, which is an unconditional advantage of this method over experimental. Research limitations/implications: The obtained simulation results showed that the increase in the volume of liquid contaminants in the inner cavity of gas gathering pipelines leads to an increase in pressure losses above the value provided by the technological regime. To achieve maximum cleaning of gas gathering pipelines, it is necessary to develop a new method that will combine the considered. Practical implications: The performed experimental results make it possible to take a more thorough approach to cleaning the inner cavity of gas gathering pipelines and to forecast in advance to what extent the hydraulic efficiency of gas gathering pipelines can be increased. Originality/value: The obtained results of CFD simulation of gas-dynamic processes in lowered sections of gas pipelines with liquid contaminants, experimental studies of the effectiveness of various methods of cleaning the inner cavity of gas gathering pipelines has original value.

Design/methodology/approach: The research methodology consists in determining the hydraulic efficiency of gas gathering pipelines before and after cleaning their inner cavity with foams with different expansion ratios and comparing the obtained values, which allows to objectively assess the efficiency of this cleaning method. The studies were performed within the framework of research and development work by the specialists of the Ukrainian Scientific Research Institute of Natural Gases. Findings: The pilot testing was carried out to determine the efficiency of cleaning the inner cavity of gas gathering pipelines with foams with different expansion ratios. It showed positive results. It was determined that cleaning the inner cavity of gas gathering pipelines with foams with the expansion ratio from 80 to 90 led to an increase in the hydraulic efficiency coefficient by 10.5%, and with foams with the expansion ratio from 50 to 60 – by 5.7%. The measures taken to clean the inner cavity of gas gathering pipelines from liquid contaminations have proven their efficiency and can be recommended for other fields. Research limitations/implications: The obtained results show that it is reasonable to conduct the experimental studies on the efficiency of cleaning the inner cavity of gas gathering pipelines with the foams with higher expansion ratios. To achieve the maximum quality of cleaning the gas gathering pipelines, it is necessary to develop a new method that will combine the use of foam and gel piston.Practical implications: The performed experimental studies help to take a more reasonable approach to cleaning the inner cavity of gas gathering pipelines with foams and to predict in advance the effect of the foam expansion ratio on the hydraulic efficiency of gas gathering pipelines. Originality/value: The experimental studies on the effect of foam expansion ratios on the hydraulic efficiency of gas gathering pipelines are original.
