Book Oil Recovery Enhancement from Fractured Low Permeability Reservoirs Annual Report October 1 1990 September 31 1991 Annex 4

Download or read book Oil Recovery Enhancement from Fractured Low Permeability Reservoirs Annual Report October 1 1990 September 31 1991 Annex 4 written by and published by . This book was released on 1991 with total page 62 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. The 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. Shear-wave splitting concepts were used to estimate fracture orientations from Vertical Seismic Profile, VSP data. Several programs were 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 Imbibition Process - Laboratory displacement as well as Magnetic Resonance Imaging, MRI and Computed Tomography, CT imaging studies have shown the carbonated water-imbibition displacement process significantly accelerates and increases recovery from oil saturated, low permeability rocks. Field Tests - Two operators amenable to conducting a carbonated water flood test on an Austin Chalk well have been identified. Feasibility studies are presently underway.

Book Oil Recovery Enhancement from Fractured Low Permeability Reservoirs Quarterly Report January 1 1993 March 31 1993

Download or read book Oil Recovery Enhancement from Fractured Low Permeability Reservoirs Quarterly Report January 1 1993 March 31 1993 written by and published by . 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.

Book Microbial Enhanced Oil Recovery Research Annex 5 Summary Annual Report 1990 1991

Download or read book Microbial Enhanced Oil Recovery Research Annex 5 Summary Annual Report 1990 1991 written by and published by . This book was released on 1991 with total page 9 pages. 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.

Book Unconventional Gas Reservoirs

Download or read book Unconventional Gas Reservoirs written by M. Rafiqul Islam and published by Elsevier. This book was released on 2014-10-23 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas, especially unconventional gas, has an increasingly important role in meeting the world's energy needs. Experts estimate that it has the potential to add anywhere from 60-250% to the global proven gas reserve in the next two decades. To maintain pace with increasing global demand, Unconventional Gas Reservoirs provides the necessary bridge into the newer processes, approaches and designs to help identify these more uncommon reservoirs available and how to maximize its unconventional potential. Loaded with reservoir development and characterization strategies, this book will show you how to: Recognize the challenges and opportunities surrounding unconventional gas reservoirs Distinguish among the various types of unconventional reservoirs, such as shale gas, coalbed methane, and tight gas formations Drill down and quantify the reservoir’s economic potential and other critical considerations Gain practical insights and tools to efficiently identify, appraise, and develop unconventional gas reservoirs Understand various techniques used to analyze reservoir parameters and performance as well as how they were applied to numerous real-world case studies Upgrade to the latest information on perspectives and insights with discussion of key differences used for today’s unconventional gas characterization versus original conventional methods that failed in the past
