This book was released on 1991 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the investigative efforts for this jointly funded DOE-State of Texas research project achieved during the 1990--1991 year may be summarized as follows: Geological Characterization -- Detailed maps of the development and hierarchical nature the fracture system exhibited by Austin Chalk outcrops were prepared. These results of these efforts were directly applied to the development of production decline type curves applicable to a dual fracture-matrix flow system. Analysis of production records obtained from Austin Chalk operators illustrated the utility of these type curves to determine relative fracture/matrix contributions and extent. Well-log response in Austin Chalk wells has been shown to be a reliable indicator of organic maturity. (VSP) Vertical-Seismic Profile data was used to use shear-wave splitting concepts to estimate fracture orientations. Several programs were to be written to facilitate analysis of the data. The results of these efforts indicated fractures could be detected with VSP seismic methods. Development of the (EOR) Enhanced Oil Recovery Imbibition Process -- Laboratory displacement as well as MRI and CT imaging studies have shown the carbonated water-imbibition displacement process significantly accelerates and increases recovery of an oil saturated, low permeability core material, when compared to that of a normal brine imbibition displacement process. A study of oil recovery by the application of a cyclic carbonated water imbibition process, followed by reducing the pressure below the bubble point of the CO2-water solution, indicated the possibility of alternate and new enhanced recovery method. The installation of an artificial solution gas drive significantly increased oil recovery. The extent and arrangement of micro-fractures in Austin Chalk horizontal cores was mapped with CT scanning techniques. The degree of interconnection of the micro-fractures was easily visualized.

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.

This book was released on 1992 with total page 219 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work is to develop an engineering framework for the exploitation of microorganisms to enhance oil recovery. Specific goals include: (1) the production, isolation, chemical characterization and study of the physical properties of microbially produced surfactants; (2) development of simulators for MEOR; (3) model studies in sandstone cores for the characterization of the interactions between growing microbially cultures and oil reservoirs, ; (4) design of operation strategies for the sequential injection of microorganisms and nutrient in reservoirs. Accomplishments are: (1) ultra low interfacial tensions (0.003 mN/M) were obtained between decane and 5% NaCl brine using biosurfactants obtained from Bacillus Licheniformis, JF-2 which is the lowest IFT ever reported for biosurfactants; (2) a method to was developed isolate the biosurfactant from the growth medium; (3) the structure of the isolated biosurfactant has been determined; (4) several techniques have been proposed to increase the yield of the surfactant; and (5) an MEOR simulator has been completed.
