This book was released on 2015-05-04 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas condensate reservoir has been demonstrated as a highly complex phase and flow properties as a result of the appearance of condensate blockage near the well-bore region. This challenge can cause a significant reduction of well productivity and even seized due to decrease in pressure around the well-bore. The reduction in the reservoir pressure could be treated by shutting in the well for a period in order to build-up the reservoir pressure. Likewise, injection fluids are preferably used to maintain the reservoir pressure above dew point to avoid retrograde condensation which can result in condensate blockage. An accurate prediction should be made to achieve informed and resourceful decisions of reservoir management and sustain well productivity. In this report, the improved productivity of hydrocarbon and maintaining the reservoir pressure of a gas condensate reservoir under water, carbon dioxide and water followed by CO2 injections were studied using ECLIPSE 300 compositional reservoir simulator for 1D, 2D and 3D models.

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.

Book excerpt: Simulation of the mixing of carbon dioxide and methane is critical to modeling gas reservoir processes induced by the injection of carbon dioxide. We have compared physical property estimates and simulation results of the mixing of carbon dioxide and methane gases from four numerical simulation codes. Test Problem 1 considers molecular diffusion in a one-dimensional stably stratified system. Test Problem 2 considers molecular diffusion and advection in an unstable two-dimensional system. In general, fair to good agreement was observed between the codes tested.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing energy demand combined with public concern for the environment obligates the oil industry to supply oil and natural gas to the public while minimizing the carbon footprint due to its activities. Today, fossil fuels are essential in meeting the global energy needs, but have the undesirable outcome of producing carbon dioxide. Carbon dioxide (CO2) injection in reservoirs is an appealing Enhanced Oil/Gas Recovery method for increasing hydrocarbon production by using the miscible interactions between hydrocarbon and carbon dioxide. Carbon dioxide flooding is beneficial to the environment and to petroleum producers, since it can store carbon dioxide while increasing oil and natural gas production. A practical challenge in combining CO2 Sequestration with Enhanced Gas Recovery (EGR) is determining the optimal process parameters that maximize the project value. This research describes the development of a procedure to determine the best process conditions for the CO2 EGR and Sequestration process. Analysis includes experimental work that illustrates that CO2 is able to reduce the dew point pressure of wet gas fluids and that reservoir fluid phase changes can be indicated by changes in total fluid compressiblity. In addition, compositional simulation illustrates that CO2 improves condensate and natural gas recovery. Studies show that the ideal reservoir management strategy for CO2 EGR is to set the CO2 injectors' bottom hole pressure to the initial reservoir pressure. An economic model is developed that illustrates the capital investment necessary for the CO2 EGR and Sequestration process for different capture technologies and levels of captured CO2 impurity. This economic model is utilized in conjunction with an optimization algorithm to illustrate the potential profitability of theCO2 EGR and Sequestration project. To illustrate the economic risk associated with CO2 EGR and Sequestration project, probabilistic analysis is used to illustrate scenarios where the technology is successful. This work is applicable to carbonate wet gas reservoirs that have significant gas production problems associated with condensate blockage. This work is also useful in modeling the economics associated with CO2 EGR and CO2 Sequestration. The strategy developed in this work is applicable to designing process conditions that correspond to optimal CO2 EGR and optimal CO2 Sequestration.

Available in PDF, EPUB and Kindle. Book excerpt: This book gives practical advice and ready to use tips on the design and construction of subsurface reservoir models. The design elements cover rock architecture, petrophysical property modelling, multi-scale data integration, upscaling and uncertainty analysis. Philip Ringrose and Mark Bentley share their experience, gained from over a hundred reservoir modelling studies in 25 countries covering clastic, carbonate and fractured reservoir types, and for a range of fluid systems – oil, gas and CO2, production and injection, and effects of different mobility ratios. The intimate relationship between geology and fluid flow is explored throughout, showing how the impact of fluid type, displacement mechanism and the subtleties of single- and multi-phase flow combine to influence reservoir model design. The second edition updates the existing sections and adds sections on the following topics: · A new chapter on modelling for CO2 storage · A new chapter on modelling workflows · An extended chapter on fractured reservoir modelling · An extended chapter on multi-scale modelling · An extended chapter on the quantification of uncertainty · A revised section on the future of modelling based on recently published papers by the authors The main audience for this book is the community of applied geoscientists and engineers involved in understanding fluid flow in the subsurface: whether for the extraction of oil or gas or the injection of CO2 or the subsurface storage of energy in general. We will always need to understand how fluids move in the subsurface and we will always require skills to model these quantitatively. The second edition of this reference book therefore aims to highlight the modelling skills developed for the current energy industry which will also be required for the energy transition of the future. The book is aimed at technical-professional practitioners in the energy industry and is also suitable for a range of Master’s level courses in reservoir characterisation, modelling and engineering. • Provides practical advice and guidelines for users of 3D reservoir modelling packages • Gives advice on reservoir model design for the growing world-wide activity in subsurface reservoir modelling • Covers rock modelling, property modelling, upscaling, fluid flow and uncertainty handling • Encompasses clastic, carbonate and fractured reservoirs • Applies to multi-fluid cases and applications: hydrocarbons and CO2, production and storage; rewritten for use in the Energy Transition.
