This book was released on 1997 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current project is a systematic research effort that will lead to a new generation of predictive tools for gas injection processes in heterogeneous reservoirs. The project is aimed at quantifying the impact of heterogeneity on oil recovery from pore level to reservoir scales. This research effort is, therefore, divided into four areas: (1) Laboratory Gas Injection Experiments (2) Network Modeling of Three-Phase Flow (3) Benchmark Simulation of Gas Injection Processes (4) Streamline Simulator Development. The status of the research effort in each area is reviewed briefly in the following section. Project Status Laboratory Gas Injection Experiments Gravity drainage of oil in the presence of gas and water has found to result in high recovery efficiency. Numerical representation of the high recovery efficiency requires a good understanding of three-phase relative permeabilities, especially at low oil saturations. Ph. D student Akshay Sahni has analyzed experimental results of selected three-phase displacements in the literature and compared them with the newly developed mathematical theory of three-phase flow in porous media. He approximated the relative permeability of each phase as a polynomial function of the saturation of that phase. An excellent agreement has been obtained between the measured and the calculated saturation paths. The analytical solution has also been checked by performing numerical simulations. Fig. 1 is an example of the comparisons of experiments, mathematical theory and numerical simulations. Fig. 1 shows a situation in which gas is injected into a system with high oil saturation and the formation of an oil bank is observed. The experiments in the literature were generally conducted at relatively high oil saturations. We have designed a series of gravity drainage experiments to measure three-phase relative permeability at low oil saturations. The CT scanner in the Petroleum Engineering Department at Stanford has been modified to measure in-situ saturations of vertically-placed samples, which is necessary in gravity drainage experiments. Akshay Sahni has finished a series of gravity drainage experiments in sand packs using different model oils to calibrate the scanner and to investigate the effect of spreading coefficient on three-phase relative permeability. A procedure has been developed for calculating relative permeabilities from measured in-situ saturations.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses various aspects of percolation mechanics. It starts with the driving forces and driving modes and then examines in detail the steady state percolation of single-phase incompressible fluids, percolation law of natural gas and percolation of non-Newtonian fluids. Progressing from simple to complex concepts, it also analyzes Darcy’s law, providing a basis for the study of reservoir engineering, oil recovery engineering and reservoir numerical simulation. It serves as a textbook for undergraduate students majoring in petroleum engineering, petroleum geology and groundwater engineering, and offers a valuable reference guide for graduate students, researchers and technical engineers engaged in oil and gas exploration and development.

Mayorquin-Ruiz and published by . This book was released on 2015 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alternatives for enhanced oil recovery processes in heavy oil containing deep naturally fractured reservoirs (NFR) are limited due to excessive heat losses when steam is injected. Air injection at high temperature oxidation conditions (in-situ combustion) has been considered as an alternative to aqueous based thermal applications. However, its implementation has serious limitations including poor areal distribution of injected air and poor combustion efficiency due to the heterogeneous nature of these reservoirs as well as the safety risk of unconsumed injected oxygen (O2) reaching the production wells. Taking advantage of the low cost and availability of air, one option is to use air at low temperature conditions (low temperature oxidation, LTO) as a pressurizing agent in NFR. Oxygenated compounds are generated at these conditions resulting in oil viscosity increase, reducing fluid mobility. In order to minimize this detrimental effect, a combination of air injection with hydrocarbon solvents can be applied. The objectives of this thesis are to evaluate air injection at LTO conditions in NFR containing heavy oil as a way to improve oil recovery, to clarify the effect of hydrocarbon solvent addition into air on oil recovery and O2 consumption, and to propose optimal conditions (temperature, air/solvent ratio) and implementation strategies for an efficient use of this suggested method. Comprehensive laboratory and numerical simulation studies were conducted to achieve these objectives. Static diffusion experiments--simulating cyclic gas injection (huff-and-puff)--were carried out by soaking heavy oil saturated cores into a reactor filled with gas representing a matrix/fracture system. Oil recovery and O2 consumption were the main parameters assessed and an extensive set of variables including rock type, temperature, fracture volume, solvent type, matrix size, gas injection sequences, and soaking times were studied. From experimental studies, the following conclusions were made: 1.Gas sequence design affects oil recovery, 2.O2 consumption in air cycles is higher after the core is soaked into butane rather than propane, 3.It is beneficial to soak cores in air+C3 mixture rather than pure air or solvent; i.e., lower O2 concentration in produced gas, less solvent usage, higher and faster oil recovery compared to alternate injection of air and C3. Then, core scale numerical simulation models were created for modeling lab experiments for a sensitivity analysis on Air/C3 ratio and matrix size. The results show that the process is extremely sensitive to matrix size and optimization of air injection (assisted by hydrocarbon solvents) can be achieved based on the minimized hydrocarbon solvent for a given matrix size. Additionally, a sensitivity analysis was performed using an up-scaled numerical model to the field scale containing meter-scale matrix blocks. It was observed that oil production mechanisms acting in a matrix block surrounded by gas filling the fractures are predominantly gas-oil gravity drainage, effective diffusion, and voidage replacement of oil by gas. Finally, a numerical simulation sector model of a hypothetical NFR was created and several air-gas injection sequences were analyzed. It was concluded that injection of air (LTO conditions) and propane represents an alternative for heavy oil recovery from NFRs at the field scale, and an optimum production time/soaking time ratio can be obtained for given gas injection sequences (type of gas and injection/soaking durations), temperature, and block sizes.

Available in PDF, EPUB and Kindle. Book excerpt: Numerical simulation is an essential tool in the design and development of oil recovery strategies, and is particularly important for the more costly and marginally economic recovery schemes contemplated for heavy oil and bitumen recovery. One process that has shown excellent promise is the horizontal-well gravity-drainage stream injection process. In field trials, it was found that the formation is heated only in a spherical zone around the injection well. To resolve these problems, this report develops a two-dimensional simulator to track the location of the steam front explicitly within a finite-difference procedure, so that the phenomena at the stream front can be more accurately simulated. The report presents details of the mathematical analysis required to incorporate the time-dependent coordinate transformation and the finite-difference representation.
