Book excerpt: Thermal methods, and particularly steam injection, are currently recognized as the most promising for the efficient recovery of heavy oil. Despite significant progress, however, important technical issues remain open. Specifically, still inadequate is our knowledge of the complex interaction between porous media and the various fluids of thermal recovery (steam, water, heavy oil, gases, and chemicals). While, the interplay of heat transfer and fluid flow with pore- and macro-scale heterogeneity is largely unexplored. Objectives of this work contract are to carry out new studies in the following areas: displacement and flow properties of fluids involving phase change in porous media; flow properties of mobility control fluids (such as foam); and the effect of reservoir heterogeneity on thermal recovery. Specific projects address the need to improve heavy oil recovery from typical reservoirs as well as less conventional fractured reservoirs producing from vertical or horizontal wells. In the area of vapor-liquid flow, we present the continuation of work on the pore network modeling of bubble growth in porous media driven by the application of a prescribed heat flux or superheat. The scaling of bubble growth in porous media is also discussed. In another study we study the problem of steam injection in fractured systems using visualization in micromodels. The interplay of drainage, imbibition and bubble growth problems is discussed.

This book was released on 1993 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers work performed in the various physicochemical factors for the improvement of oil recovery efficiency. In this context, three general areas were studied: (i) The understanding of vapor-liquid flow in porous media, whether the flow is internal (boiling), external (steam injection) or countercurrent (as in vertical heat pipes); (ii) The effect of reservoir heterogeneity, particularly as it regards fractured systems; (iii) The flow properties of additives for the improvement of recovery efficiency, in particular the injection of caustic and foams. The studies completed under this contract involved ap three research tools, analysis, computation and experiments. We have focused on pore level modeling using pore networks and on flow visualization using Hele-Shaw cells. Experiments involving core samples were conducted for the chemical additives investigation. Finally, simulation at the pore scale, pore network scale and reservoir scale were also undertaken. Part of the work has been detailed in five DOE Technical Reports as shown at the end of this report.

Book excerpt: This report covers work performed in the area related to the physicochemical factors for the improvement of the oil recovery efficiency in steamfloods. In this context, three general areas are studied: (1) The understanding of vapor-liquid flow in porous media, whether the flow is internal (boiling), external (steam injection) or countercurrent (as in vertical heat pipes). (2) The effect of reservoir heterogeneity, particularly as it regards fractured systems and long and narrow reservoirs (which are typical of oil reservoirs). (3) The flow properties of additives for the improvement of recovery efficiency, in particular the properties of foams.

This book was released on 1996 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this contract is to carry our fundamental research in heavy oil recovery in the following areas: displacement and flow properties of fluids involving phase change (condensation-evaporation) in porous media; flow properties of mobility control fluids (such as foam); and the effect of reservoir heterogeneity on oil recovery. The specific projects are motivated by and address the need to improve heavy oil recovery from typical reservoirs as well as less conventional fractured reservoirs. This report covers the work performed in these three areas in the past year. In the area of vapor-liquid flow we present a theoretical and numerical study of steam injection in a pore network. We characterize the displacement in terms of an effective mobility ratio and heat transfer parameters. Displacement patterns axe identified in the parameter space. In another study we discuss the problem of steam injection in fractured systems using visualization with micromodels. The interplay of drainage, imbibition and bubble growth is visualized. Conclusions are reached regarding the potential for steamflooding fractured systems. A third study focuses on the development of a pore-network model for foam formation and propagation in porous media. This model, for the first time, accounts for the fundamental mechanisms of foam propagation at the microscale and leads to the determination of various parameters that are currently treated empirically. The effect of viscous forces in displacements in heterogeneous media is described in two separate studies, one involving an extension of percolation theory to account for viscous effects, and another discussing the effect of geometry in general displacement processes.

Book excerpt: This report summarizes research progress made during the period October 1, 1988--September 30, 1989. We report advances in the following general areas: (1) chemical-steam simulation model, (2) vapor-liquid flow in porous media, (3) foam flow in porous media, (4) caustic flooding at elevated temperatures, and (5) reservoir heterogeneity. Additional efforts have been devoted in the last quarter of the past year in upgrading and debugging the simulator. New features were added in three-phase relative permeabilities, the vertical equilibrium and the phase behavior subroutines. 123 refs., 79 figs., 2 tabs.
