This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the possibility of industrial CO2 storage in shale gas reservoirs is investigated numerically by using one of the most advanced computational simulators in oil and gas industry, PSU-SHALECOMP, which is a compositional dual porosity, dual permeability, multi-phase reservoir simulator. A computationally inexpensive "stimulated reservoir volume" (SRV) model which has the ability to generate a similar behavior of an equivalent discrete fracture network model is defined and implemented. Three different commercial production profiles are history-matched by using the SRV approach effectively. It is re-proved that implementation of the horizontal borehole technology and hydraulic fracturing are the two most important factors that will increase the efficacy of methane production and carbon dioxide injection processes. It is observed that significantly large percentage of the produced gas originates from the fractured zone so as significantly large percentage of the injected gas will end up occupying the pore spaces in the fractured zone. Injection of carbon dioxide into undepleted shale gas reservoirs is not promising because of its ultra-tight permeability characteristics. Injection of carbon dioxide into shale gas reservoirs that have produced approximately 30\% of the initial gas in place is promising. It is observed that when 30\% of shale gas production is achieved, up to 70\% of the depleted gas volume is expected to be replaced by carbon dioxide.The storage capacity of the depleted shale gas reservoir can be increased by injecting carbon dioxide at a rather low rate. A low rate injection of carbon dioxide will increase its residence time in the flow domain increasing its chances for adsorption.If the SRV zones of the production and injection wells are not in direct communication, it is not expected to see carbon dioxide breakthrough at the producing well. It is also investigated that contribution of carbon dioxide in enhancing the shale gas recovery is negligible. The study includes developments of four artificial neural network tools that have different production of methane and injection of carbon dioxide constraints. These four forward tools can produce production and injection profiles of a given system within an error range of 3.83\% to 5.23\%. This part of the study also includes four additional artificial neural network tools that predicts wellbore design and hydraulic fracture characteristics within an error range of 8.24\% to 9.93\%.

Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide sequestration is a technology that is being explored to curb the anthropogenic emission of CO2 into the atmosphere. Carbon dioxide has been implicated in the global climate change and reducing them is a potential solution. The injection of carbon dioxide for enhanced oil recovery (EOR) has the duel benefit of sequestering the CO2 and extending the life of some older fields. Sequestering CO2 and EOR have many shared elements that make them comparable. This volume presents some of the latest information on these processes covering physical properties, operations, design, reservoir engineering, and geochemistry for AGI and the related technologies.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There is undeniable evidence that concentration of carbon dioxide in the atmosphere is rising at an increasingly rapid rate primarily as the result of burning fossil fuels. Although the debate continues, most of the scientific community believes that higher levels of atmospheric CO2 will lead to a significant warming of the Earth's climate and that there is already evidence that this is occurring. There are two ways to ameliorate this problem. One is to significantly reduce production of CO2, which is primarily a political-economic problem, and the other is to remove CO2 from emissions and/or the atmosphere and find some way to sequester it. Several possible ways to sequester CO2 are under investigation or have been suggested. These include removal by chemical reaction, deep seabed disposal, and pumping supercritical CO2 into various subsurface environments. Sequestration of carbon dioxide in depleted gas reservoirs appears to be a viable option, with a possible economic spin-off from the recovery of significant gas reserves. At the elevated temperatures and pressures encountered in reservoirs, carbon dioxide behaves as a supercritical fluid. Under these conditions, little was known regarding the, diffusion of carbon dioxide in natural gas, and displacement of natural gas by carbon dioxide. A major objective of this research was to obtain the necessary data to model these processes. Also, the added CO2 will react with reservoir waters that are often chemically complex high ionic strength brines making them more acidic. This can result in the dissolution of calcium carbonate (calcite) that is a common host rock or sandstone cement in reservoirs and lead to potentially serious problems for CO2 injection and the integrity of the reservoir. It was consequently a second major objective of this project to determine calcite solubility and dissolution kinetics in solutions representative of subsurface brines and produce a general dissolution rate equation. Both objectives were accomplished. Reservoir simulations indicated a large amount of CO2 would be sequestered, with the amount depending on reservoir water saturation. Simulation results also indicate a significant amount of natural gas could be produced. For an 80-acre pattern, natural gas production was calculated to be 3.2 BSCF or 63% of remaining gas-in-place for 30% reservoir water saturation. Gas revenues would help defray the cost of CO2 sequestration. Therefore, CO2 sequestration in depleted gas reservoirs appears to be a win-win technology. Considerable effort went into testing and refining the ability to predict calcite solubility in brines using a Pitzer-equation based computer model, with particular difficulties being encountered in solutions with high dissolved calcium concentrations. After that was accomplished, calcite dissolution kinetics were determined a wide range of brine compositions both including and not including potential inhibitors from 25 to 83 oC and a CO2 partial pressure from 0.1 to 1 atm. The reaction was found to be first order for undersaturations of 0.2 to ~1 and was surface controlled. The rate constant was fit to a multiple regression model, thus making it possible to predict calcite dissolution rates over a wide range of solution compositions, partial pressures of CO2 and temperature. Results indicate that equilibrium is likely to be reached relatively quickly in front of an advancing supercritical CO2 fluid.

Download or read book Analysis of the Efficacy of Carbon Dioxide Sequestration in Depleted Coalbed Methane Reservoirs written by Liyang Liu and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the viability of Carbon Dioxide (CO2) sequestration in depleted Coalbed reservoirs is investigated using Computer Modeling Group LTDs (CMG) Compositional & Unconventional Simulator (GEM). This simulator features dual-porosity and dual-permeability functions, and thus best suits the needs of the model intended. In order to imitate a stimulation fracture network around the horizontal well, a Stimulated Reservoir Volume (SRV) approach was implemented. Three different models with varied grid size, matrix properties, production rates, and injection rates were investigated in order to determine proper variable ranges for the Monte Carlo Simulation and the Artificial Neural Network (ANN) study, presented in the later part of the study.With low permeability and porosity, Coalbed methane cannot be easily produced, nor can CO2 be easily injected, without the implementation of fracture stimulation techniques. The SRV approach significantly improved case performances of both CH4 production and CO2 injection [1]. With varied production sand face pressure, production rates for each of the cases will be different. However, producers will be shut-in at a uniform minimum production rate of 300 MSCFD, followed by the opening of injectors at the same well location. Injection performances will be evaluated in this study.During the final stage of this study, three Artificial Neural Network tools were developed in order to predict various sets of data using combinations of input variables. The first tool can predict production and injection profiles of a given system with error very close or less than 20%. The second tool can predict wellbore design parameters and fracture characteristics with error less than 20%. The third tool can predict formation characteristics with error less than 20%, with the exception of one variable having larger error, yet within acceptable range.

This book was released on 2009 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas condensate reservoirs encounter a condensate blockage problem when the pressure around the wellbore falls below the dew point pressure. The amount of the liquid dropout depends on the composition of the reservoir fluid. If the percentage of liquid increases, it will restrict the production. Gas injection is the effective method to solve this problem and help increase recovery of the valuable condensate liquid. The objective of this study is to evaluate the effect of different reservoir fluid compositions on carbon dioxide injection in a gas condensate reservoir. Ten sets of reservoir compositions were selected. A compositional reservoir simulation was used to simulate the performance of carbon dioxide injection. The results show that composition of reservoir fluid has a significant effect on the optimum starting time for carbon dioxide injection. In order to maximize condensate recovery, the time to start carbon dioxide injection is the latest time that carbon dioxide injection can revaporize liquid dropout before carbon dioxide concentration reaches the limit. When the dew point pressure is high or maximum liquid dropout is low, the most optimum time of injection will be quite early. In the case that the initial reservoir pressure is equal to the dew point pressure, carbon dioxide injection rate has to be higher than the production rate in order to maximize condensate recovery. The higher injection rate will keep the reservoir pressure high. Thus, liquid dropout around the wellbore can be completely revaporized. However, if the injection rate is too high, early carbon dioxide breakthrough at the producer will cause an early abandonment of the production due to high carbon dioxide content in the produced gas. When the maximum liquid dropout is low, the most optimum injection rate will generally be high.
