Available in PDF, EPUB and Kindle. Book excerpt: Many heavy oil reservoirs are now developed by enhanced heavy oil recovery methods, such as solvent-based recovery techniques. The solvent-based recovery techniques have advantages in energy effectiveness, cost efficiency, and environmental benefits compared with other methods. In the application of solvent-based recovery techniques, many types of solvent are available, including methane (C1), propane (C3), carbon dioxide (CO2), and solvent mixture. Foamy oil flow is considered an essential mechanism and has been extensively studied. For each heavy oil-solution gas system, the flow behavior is unique, and a systematic study is necessary to understand the foamy oil mechanism better. Previously proposed simulation models did not history match the production data and pressure distribution simultaneously. This deficiency would increase the uncertainty of the simulation result and influence the subsequent evaluation or prediction of the enhanced heavy oil recovery process since the pressure incremental is not captured. This work provides an innovative methodology to characterize foamy oil flow and gas-oil two-phase flow in heavy oil-different solvent systems. For each heavy oil-solvent system, a reliable non-equilibrium simulation model is developed and validated with sand-pack model pressure depletion tests by capture the production data and pressure distribution. This work consists of a systematic simulation study using the same heavy oil sample with different types of solvent. Since the mobility ratio between the solvent and heavy oil in applying solvent-based recovery techniques is very high, the frontal instabilities are also widely observed at the two-phase interface. The instabilities grow and form the viscous fingering phenomenon. Due to the existence of viscous fingering, the breakthrough time is shortened significantly, which will impact the oil recovery and swept efficiency. Since the description and prediction of the two-phase frontal instabilities in the porous media is always a challenge, most current work is based on theoretical models and rarely validated with lab tests. In addition, previous modeling works of frontal instabilities were mainly conducted in the Hele-Shaw model or micromodel, not in the sand-pack model. Hence, previous conducted experimental works were not analyzed with the simulation study in the porous media. In this work, a simulation model is developed by adopting the Volume of Fluid (VOF) method coupled with the Level-Set (LS) method to capture and track the immiscible two-phase interface between oil and water. Then the simulation results of viscosity fingering are validated with lab tests in the porous media in terms of qualitative (frontal instability morphological characteristics) and quantitative (breakthrough time) aspects. The characterization of the frontal instabilities (viscosity fingering) is investigated under different displacing rates and viscosities. It is very challenging to describe and predict both the foamy oil flow and frontal instabilities at the same time during the enhanced heavy oil recovery process. Therefore, this research conducted simulation works and validated with lab tests for each process (foamy oil flow and viscosity fingering) separately. The conducted researches provide numerical simulation methods and reliable simulation models that could be applied to further studies on the history match and prediction of field application. Moreover, the conducted researches allow future research to consider both phenomena (foamy oil flow and viscosity fingering) that happened in the enhanced heavy oil processes by integrating the proposed simulation models in this work.
Book Synopsis Efficient Simulation of Thermal Enhanced Oil Recovery Processes by : Zhouyuan Zhu
Download or read book Efficient Simulation of Thermal Enhanced Oil Recovery Processes written by Zhouyuan Zhu and published by Stanford University. This book was released on 2011 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simulating thermal processes is usually computationally expensive because of the complexity of the problem and strong nonlinearities encountered. In this work, we explore novel and efficient simulation techniques to solve thermal enhanced oil recovery problems. We focus on two major topics: the extension of streamline simulation for thermal enhanced oil recovery and the efficient simulation of chemical reaction kinetics as applied to the in-situ combustion process. For thermal streamline simulation, we first study the extension to hot water flood processes, in which we have temperature induced viscosity changes and thermal volume changes. We first compute the pressure field on an Eulerian grid. We then solve for the advective parts of the mass balance and energy equations along the individual streamlines, accounting for the compressibility effects. At the end of each global time step, we account for the nonadvective terms on the Eulerian grid along with gravity using operator splitting. We test our streamline simulator and compare the results with a commercial thermal simulator. Sensitivity studies for compressibility, gravity and thermal conduction effects are presented. We further extended our thermal streamline simulation to steam flooding. Steam flooding exhibits large volume changes and compressibility associated with the phase behavior of steam, strong gravity segregation and override, and highly coupled energy and mass transport. To overcome these challenges we implement a novel pressure update along the streamlines, a Glowinski scheme operator splitting and a preliminary streamline/finite volume hybrid approach. We tested our streamline simulator on a series of test cases. We compared our thermal streamline results with those computed by a commercial thermal simulator for both accuracy and efficiency. For the cases investigated, we are able to retain solution accuracy, while reducing computational cost and gaining connectivity information from the streamlines. These aspects are useful for reservoir engineering purposes. In traditional thermal reactive reservoir simulation, mass and energy balance equations are solved numerically on discretized reservoir grid blocks. The reaction terms are calculated through Arrhenius kinetics using cell-averaged properties, such as averaged temperature and reactant concentrations. For the in-situ combustion process, the chemical reaction front is physically very narrow, typically a few inches thick. To capture accurately this front, centimeter-sized grids are required that are orders of magnitude smaller than the affordable grid block sizes for full field reservoir models. To solve this grid size effect problem, we propose a new method based on a non-Arrhenius reaction upscaling approach. We do not resolve the combustion front on the grid, but instead use a subgrid-scale model that captures the overall effects of the combustion reactions on flow and transport, i.e. the amount of heat released, the amount of oil burned and the reaction products generated. The subgrid-scale model is calibrated using fine-scale highly accurate numerical simulation and laboratory experiments. This approach significantly improves the computational speed of in-situ combustion simulation as compared to traditional methods. We propose the detailed procedures to implement this methodology in a field-scale simulator. Test cases illustrate the solution consistency when scaling up the grid sizes in multidimensional heterogeneous problems. The methodology is also applicable to other subsurface reactive flow modeling problems with fast chemical reactions and sharp fronts. Displacement front stability is a major concern in the design of all the enhanced oil recovery processes. Historically, premature combustion front break through has been an issue for field operations of in-situ combustion. In this work, we perform detailed analysis based on both analytical methods and numerical simulation. We identify the different flow regimes and several driving fronts in a typical 1D ISC process. For the ISC process in a conventional mobile heavy oil reservoir, we identify the most critical front as the front of steam plateau driving the cold oil bank. We discuss the five main contributors for this front stability/instability: viscous force, condensation, heat conduction, coke plugging and gravity. Detailed numerical tests are performed to test and rank the relative importance of all these different effects.

Download or read book Enhanced Oil Recovery written by Vladimir Alvarado and published by Gulf Professional Publishing. This book was released on 2010-07-30 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enhanced-Oil Recovery (EOR) evaluations focused on asset acquisition or rejuvenation involve a combination of complex decisions, using different data sources. EOR projects have been traditionally associated with high CAPEX and OPEX, as well as high financial risk, which tend to limit the number of EOR projects launched. In this book, the authors propose workflows for EOR evaluations that account for different volumes and quality of information. This flexible workflow has been successfully applied to oil property evaluations and EOR feasibility studies in many oil reservoirs. The methodology associated with the workflow relies on traditional (look-up tables, XY correlations, etc.) and more advanced (data mining for analog reservoir search and geology indicators) screening methods, emphasizing identification of analogues to support decision making. The screening phase is combined with analytical or simplified numerical simulations to estimate full-field performance by using reservoir data-driven segmentation procedures. Case Studies form Asia, Canada, Mexico, South America and the United States Assets evaluated include reservoir types ranging from oil sands to condensate reservoirs Different stages of development and information availability are discussed

Book Synopsis Enhanced Oil Recovery, II by : E.C. Donaldson
Download or read book Enhanced Oil Recovery, II written by E.C. Donaldson and published by Elsevier. This book was released on 1989-07-01 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by foremost experts in the field, and formulated with attention to classroom use for advanced studies in reservoir characterization and processes, this book reviews and summarises state-of-the-art progress in the field of enhanced oil recovery (EOR). All of the available techniques: alkaline flooding; surfactant flooding; carbon dioxide flooding; steam flooding; in-situ combustion; gas injection; miscible flooding; microbial recovery; and polymer flooding are discussed and compared. Together with Volume I, it presents a complete text on enhanced recovery technology and, hence, is an almost indispensible reference text.This second volume compliments the first by presenting as complete an analysis as possible of current oilfield theory and technology, for accomplishment of maximum production of oil. Many different processes have been developed and field tested for enhancement of oil recovery. The emerging philosophy is that no single process is applicable to all petroleum reservoirs. Each must be treated as unique, and carefully evaluated for characteristics that are amenable to one or two of the proven technologies of EOR. This book will aid the engineer in field evaluation and selection of the best EOR technology for a given oilfield. Even the emerging technology of microbial applications to enhance oil recovery are reviewed and explained in terms that are easily understood by field engineers.The book is presented in a manner suitable for graduate studies. The only addition required of teachers is to supply example problems for class work. An appendix includes a reservoir mathematic model and program for general application that can also be used for teaching.
Book Synopsis Data-driven Methods in Laboratory-scale Study of Enhanced Oil Recovery by : Timothy Isaac Anderson
Download or read book Data-driven Methods in Laboratory-scale Study of Enhanced Oil Recovery written by Timothy Isaac Anderson and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Data-driven methods have become ubiquitous across the engineering and applied sciences. In the petroleum sciences, a significant body of work has arisen applying such techniques to modeling and analysis of reservoir-scale data, but laboratory-scale data and applications have received relatively less attention. In this work, we develop data-driven methods for assimilating experimental data from two domains: image-based characterization of shale source rocks and in-situ combustion kinetics modeling. In the first half of this work, we develop methods for modality translation and synthesis of shale images, specifically for reconstructing or synthesizing 3D volumetric data when only 2D training data is available. We propose an experimental and computational workflow applying image translation and super-resolution models to predict destructive shale microscopy images from non-destructive input data. We then propose an approach to regularizing image-to-image models to improve volume reconstruction using only 2D training data. The results show that our models improve the volume prediction in terms of morphological image features and create image volumes suitable for flow simulations. We also propose a fundamentally new approach to synthesizing porous media images. Our approach is based on generative flow models and is the first approach that can generate grayscale and multimodal image data from only 2D training images. We apply this method to synthesizing baseline sandstone and limestone samples, as well as scanning electron microscopy and dual-mode focused ion beam milled scanning electron microscopy and nano-computed tomography images. The synthetic images are similar to the ground truth data in both appearance and morphological descriptors as gauged by Minkowski functionals distributions. In the second half, we develop methods for modeling and upscaling in-situ combustion chemical kinetics. We develop a data-driven model for predicting oxygen consumption during heavy oil combustion directly from laboratory data, and apply this method to simulating combustion kinetics and analyzing heating schedules for ramped temperature oxidation experiments. Our results show that a data-driven model accurately predicts heavy oil oxidation from a relatively small sample of experimental data. We then present a fully-automated parameter estimation and uncertainty quantification approach for in-situ combustion chemical reaction models. Our approach is generalized to any in-situ combustion reaction model and requires no manual history matching or parameter initialization. We apply this parameter calibration workflow to multiple reaction models for two different heavy oil samples. Our results show that reaction schemes can differ significantly in both stoichiometry and kinetics parameters when calibrated to different heavy oil samples. Very different reaction models were shown to provide fits of similar accuracy to the same heavy oil sample. Our results also suggest that it is the number of stages in pseudocomponent cracking, not the number of pseudocomponents or reactions, that most impacts the ability of a reaction model to fit oxidation data for a heavy oil sample. Overall, this work demonstrates the capabilities of using data-driven modeling to expand our characterization capabilities and improve our understanding of enhanced oil recovery processes at the laboratory-scale. It is our hope that the work presented here will enable new directions in nanoscale characterization of shales and upscaling of in-situ combustion chemical reaction models.

Available in PDF, EPUB and Kindle. Book excerpt: Within the last 10 years the world has come to a point where the easily explorable oil deposits have now been found, and it is anticipated that such deposits will be depleted by the beginning of the Twenty-first Century. However, the increasing demand of man kind for energy has caused technologists to look into ways of find ing new sources or to reevaluat:e unconventional sources which, in the past, have not been economical. In this respect, heavy crude and tar sand oils are becoming important in fulfilling the world's energy requirements. What are heavy crude and tar sand oils? There is still some confusion as to their definitions, inasmuch as they vary among organizations and countries. In an effort to set agreed meanings, UNITAR, in a meeting in February 1982 in Venezuela, proposed the following definitions (see also Table 1): 1. Heavy crude oil and tar sand oil are petroleum or petroleum like liquids or semi-solids naturally occurring in porous media. The porous media are sands, sandstone, and carbonate rocks. 2. These oils will be characterized by viscosity and density. Viscosity will be used to define heavy crude oil and tar sand oil, and density (oAPI) will be used when viscosity measurements are not available. 3. Heavy crude oil has a gas-free viscosity of 100-10000 mPa.s (cp) 3 o at reservoir temperatures, or a density of 943 kg/m (20 API) 3 o o to 1000 kg/m (10 API) at 15.6 C and at atmospheric oressure.

Available in PDF, EPUB and Kindle. Book excerpt: Cold production is a solution-gas drive process in which a reservoir saturated with live heavy oil reservoir is depleted as quickly as possible to generate relatively stable gas bubbles leading to higher oil recoveries (5–10% original oil in place (OOIP)) than for light oils (2–5% OOIP). More specifically, these bubbles increase the oil/gas mixture compressibility, which maintains the reservoir pressures for longer times than for light oils.

This book was released on 2018 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal enhanced oil recovery techniques have been considered as the best approach to produce heavy oil; however, hybrid methods, which are combinations of different oil recovery methods, reveal more promise in enhancing oil production from heavy and viscose reservoirs. In this research, we investigate improving recovery from heavy oil reservoirs, considering steam foam method to control the mobility of steam and oil in such reservoirs, and delivering proper amount of heat to reservoir in order to reduce oil viscosity. In this thesis, a compositional K-value based reservoir simulator, CMG-STARS, was used to build simulation models for all case studies. Steam table is used to calculate the phase change during steam injection and to capture latent heat effect on energy balance and mass balance equations. CMG-STARS empirical foam model is used to capture mobility of steam in the presence of surfactant. Simulation models are tuned with experimental core data and field history data. Simulation results illustrated that a considerable increase in oil recovery is obtained when steam foam is used. It is also observed that foam parameters, which was used in modeling, affects oil recovery, reservoir average temperature, average pressure and gas saturation. Optimized foam parameters were determined considering oil recovery, average reservoir temperature, and average reservoir pressure. Finally, simulations revealed that field and simulation results were in good agreement with field data, and that steam foam oil recovery method has the potential to become a promising oil recovery method for heavy oil reservoirs.
