Book excerpt: Critical gas saturation and solution gas drive performance of a heavy oil (?0 = 17,000 cp) in a Berea core sample was measured. The critical gas saturation is less than 1.5 percent. But, the solution gas drive process for the heavy oil, unlike the light oil, is very efficient. While reducing the system pressure from a bubble point pressure of 445 psia to a pressure of 330 psia, 11 percent of the oil was produced from the core. In view of the high recovery due to solution gas drive, a duplicate experiment is being conducted. The pressure will be lowered to near 50 psia in the duplicate experiment.

Book excerpt: We have developed a simple method to account for reinfiltration and capillary continuity processes in a grid cell that may contain a large number of matrix blocks. This method requires fine grid simulation of a three-block stack. The proposed technique also takes into account the variation of capillary pressure, and even permeability and height variation among various matrix blocks reasonably well.

This book was released on 1996 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of experiments have been performed to study water injection in fractured porous media. These experiments reveal that: (1) the co-current imbibition may be the primary flow process in water-wet fractured media, and (2) the imbibition may result in over 20 percent recovery from very tight rock (Austin Chalk with K{sub ma} of the order of 0.01 md) for an imbibition period of about 2 months. Theoretical consideration reveal that the exponential function of Aronofsky et al. [''A Model for the Mechanism of Oil Recovery from Porous Matrix Due to Water Invasion In Fractured Reservoirs, '' Trans. AIME (1958) 213, 17-19] does not describe the early-time, but may represent the late-time recovery.

This book was released on 1997 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase flow in fractured porous media is a complex problem. While the study of single phase flow in a fractured or a layered medium can be pursued by some kind of averaging process, there is no meaning to averaging two-phase flow when capillarity is an active force. For a two-layer system comprised of high and low permeable layers, the performance of gas-oil gravity can be less efficient than the homogeneous low permeable medium. On the other hand, heterogeneity may enhance water imbibition due to capillarity. Due to the above and various other complexities, current tools for predicting the performance of fractured hydrocarbon reservoirs are not reliable. Based on the research work carried out at the Reservoir Engineering Research Institute, and some other Institutions, a good deal of progress has been made in recent years. But still we are a long way from good predictive reservoir models. In this final report, we summarize some of our achievements in the understanding of multiphase flow in fractured media. Since some of the features of two-phase flow in fractured and layered many are similar due to the capillary forces, the work includes progress in both types of media. There are some basic issues of flow in both fractured and unfractured media that are currently unresolved. These issues include: (1) new phase formation such as the formation of liquid phase in gas condensate reservoirs, and gas phase formation in solution gas drive process and (2) composition variation due to thermal convection and diffusion processes. In the following, a brief summary of our findings in the last three years during the course of the project is presented.

This book was released on 1993 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress reports are presented for project 2-supersaturation, critical saturation and residual gas saturation in porous media and for project 5-simulation of fractured reservoirs. Under project 2, a visual high-pressure core-holder has been designed and constructed to be used in critical gas saturation and some other measurements. The apparatus has been used to measure critical gas saturation for a low viscosity mixture. These measurements reconfirm the investigators' previously published data that critical gas saturation for low viscosity fluids are low-around 1 percent. The apparatus is being currently used to measure critical gas saturation of an 11 API oil. Unlike light oils, heavy oil reservoirs, especially fractured heavy oil reservoirs might have an extremely high recovery efficiency with solution gas-drive. The critical gas saturation is an important element of recovery efficiency for such reservoirs.

This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to assist the recovery of non contacted oil from known reservoirs on the Outer Continental Shelf in the Gulf of Mexico. History matching and prediction runs have been completed on the B-35-K reservoir, history matching has been completed on the B-65-G reservoir and on Reservoir 3. Modifications to BOAST II and MASTER consisted of developing codes to handle steeply dipping oil reservoirs and a radial grid format for near wellbore studies. Modifications for steeply dipping reservoirs have been successfully implemented and tested against commercial simulators in the PC version of BOAST II, renamed BOAST III. At present, modifications to BOAST II for radial grid systems are producing acceptable results in a 2-D model. A paper was presented at the 1994 ACM Symposium on Applied Computing in Phoenix, Arizona, March 6--8, 1994 on these results. Modifications have also been successfully implemented in the MASTER simulator. It is presently undergoing industry testing for validity. Laboratory investigations continued but were slowed by several unforeseen incidences involving broken apparatus and inability to receive parts due to the California earthquake. Predictive models for undeveloped oil and immiscible/miscible processes began. The methodology for determination of undeveloped potential has been completed. The design of the miscible and updip displacement models as well as the design of the economic and timing models is underway. The coding and calibration of the models will begin soon.

This book was released on 1993 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our 1993 third quarter report discusses the results of our work on: (1) gas-oil gravity drainage in layered media; and, (2) the influence of viscous forces on gas-oil flow in fractured porous media. For sometime, we have been working on the incorporation of reinfiltration and capillary continuity concepts in a dual-porosity model. A simple and accurate technique has been developed for this purpose. The experiments on gas-oil gravity drainage in layered media are intended to: (1) verify our theoretical analysis; (2) provide more insight; and, (3) provide a guide for the simulation of gas-oil gravity drainage at field scale. On the first objective, the experiments confirm that gas-oil gravity drainage could result in a downward gas fingering phenomenon. Without capillary pressure, downward gas fingering could not realize. The experiments also show that drainage from a less permeable layer would be an extremely slow process. This is similar to the drainage performance of matrix blocks in fractured porous media. Apparently, relative permeability to gas (i.e. gas mobility) may be important for flow in layered porous media. The project on the effect of viscous forces on gas-oil displacement in fractured porous media has taken longer than anticipated. For the first time, in gravity drainage experiments of the matrix-fracture configuration used in this project, we could not obtain reproducible results. After several tests, we teamed that the surface tension of the normal-decane/air system changes in the presence of the coating cover which was used in the experimental assembly of this project. We removed the coating. The experiments can now be reproduced. The data show that there is a strong effect of viscous forces on matrix/fracture flow. A small imposed pressure gradient results in a substantial amount of oil recovery. After performing 3-4 more tests, the data will be analyzed and an appropriate model will be developed to relate experimental data to field conditions.

Quarterly Progress Report, April 1, 1996--June 30, 1996 written by and published by . This book was released on 1996 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have developed a phenomenological model for critical condensate saturation. This model reveals that critical condensate saturation is a function of surface tension and contact angle hysteresis. On the other hand, residual oil saturation does not have such a dependency. Consequently, the selection of fluids in laboratory measurements for gas condensate systems should be made with care.

This book was released on 1993 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress reports are presented for the following: Subtask l-- interpreting and predicting fractures; Subtask 2--relating recovery to well-log signatures; and Subtask 4--mathematical modeling. Some of the highlights are as follows; substantial improvement in the determination of the orientation of the fractures has been obtained when source imbalances are corrected; further improvement is achieved when the down-hole geophones are assumed to be in the direction of the sources and their coupling variations corrected; petrographic analysis of microseams was conducted on 16 thin sections to determine the gross composition and relationship of seams to microfractures; the semi-analytical model was used to describe the laboratory imbibition oil recovery behavior by plain water and carbonated waterflood at 70°F, 110°F and 150°F; and the compositional, dual-porosity numerical model (COMABS) was used to describe the laboratory imbibition oil recovery from a chalk core.
