Book excerpt: Experiments at NIPER have demonstrated that oil mobilization by microbial formulations is not merely the result of the effects of the metabolic products from the in situ fermentation of nutrient. A combination of two microorganisms, Bacillus licheniformis, NIPER and a Clostridium species (NIPER 6) was determined to be an effective microbial formulation for the recovery of residual crude oil in porous media. Flask tests with various nutrients and environmental conditions were used to evaluate the growth and metabolite production of NIPER 1 and 6. Several interfacial tension (IFT) measurements were conducted using certain metabolic products from the combined microbial cultures NIPER 1 and NIPER 6. Nonane was used as the oil for these experiments, since crude oil from Delaware-Childers field emulsifies very easily. The IFT of a selected microbial formulation were measured with two different crude oils using brines of varying salinities. Comparisons were made with saline brines containing only the nutrient and with microbial metabolite solutions from which the active cells have been removed by filtration to isolate the specific effects of the microbial cells. Etched-glass micromodel studies showed that the microbial formulation effectively mobilized crude oil trapped after waterflooding. Wettability alteration and unsteady-state relative permeability tests were performed in Berea Sandstone cores. 16 refs., 17 figs., 12 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The use of microorganisms and their metabolic products to stimulate oil production is currently receiving renewed interest worldwide. This technique involves the injection of selected microorganisms into the reservoir and the subsequent stimulation and transportation of their in situ growth products, in order that their presence will aid in further reduction of residual oil left in the reservoir after secondary recovery is exhausted. Although unlikely to replace conventional microbial enhanced oil recovery, this unique process seems superior in many respects. Self-duplicating units, namely the bacteria cells, are injected into the reservoir and by their in situ multiplication they magnify beneficial effects. This new approach to enhancement of oil recovery was initiated in 1980 and the first results were published in the proceedings of two international conferences. This book evolved from these conferences, and was designed to encompass all current aspects of microbial enhanced oil recovery: the development of specific cultures, increase of the population for field application, various methods for field applications and the results, and the environmental concerns associated with this newly developed technology. It provides a comprehensive treatise of the subject, and is arranged to show the laboratory development of microbes suited to microbial enhanced oil recovery and the perpetuation of the special cultures in a petroleum reservoir. Thus, this book has specific usefulness in the laboratory, the oilfield and the classroom. Although not written as a text book, it can be used as a reference volume for graduate studies in enhanced oil recovery.

This book was released on 2020-07-18 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selection of the optimal recovery method is significantly influenced by economic issues in today’s oil and gas markets. Consequently, the development of cost-effective technologies, which bring maximum oil recovery, is the main interest in today’s petroleum research communities. Theory and Practice in Microbial Enhanced Oil Recovery provides the fundamentals, latest research and creditable field applications. Microbial Enhanced Oil Recovery (MEOR) is potentially a low-priced and eco-friendly technique in which different microorganisms and their metabolic products are implemented to recover the remaining oil in the reservoir. Despite drastic advantages of MEOR technology, it is still not fully supported in the industry due to lack of knowledge on microbial activities and their complexity of the process. While some selected strategies have demonstrated the feasibility to be used on a mass scale through both lab and field trials, more research remains to implement MEOR into more oil industry practices. This reference delivers comprehensive descriptions on the fundamentals including basic theories on geomicrobiology, experiments and modeling, as well as current tested field applications. Theory and Practice in Microbial Enhanced Oil Recovery gives engineers and researchers the tool needed to stay up to date on this evolving and more sustainable technology. Covers fundamental screening criteria and theories selective plugging and mobility control mechanisms Describes the basic effects on environmental parameters and the mechanics of simulation, including microbial growth kinetics Applies up to date practical applications proven in both the lab and the field
Download or read book Microbial Enhancement of Oil Recovery Recent Advances written by E.C. Donaldson and published by Elsevier. This book was released on 1991-04-03 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: This conference was instituted to examine field activities in Microbial Enhancement of Oil Recovery. The U.S. Department of Energy has sponsored several field projects and the details from some of these were presented, as well as a few from industry. The balance of the program was concerned with new developments in research. Today's oil production technology leaves one third to one half of the original oil in place in the reservoir at abandonment of secondary recovery (waterflooding). This leaves a very large target for microbial enhanced oil recovery which was shown by the research papers of this conference to be capable of producing up to 50% of the residual oil. The field trials show that the normal projected oil production decline curve can be reversed, or leveled off by microbial enhancement of oil recovery. This conference has shown that a variety of applications are possible to correct oilfield problems as well as to enhance oil recovery. Among these is the suppression of hydrogen sulfide production which alone is a tremendous advance because of the large quantity of sour oil production. If hydrogen sulfide production can be curtailed it would increase the value of the produced oil, decrease it toxicity, and largely decrease it corrosiveness. All of these would be welcome both in the field and at the petroleum refinery where special precautions must be taken to process sour crude oil. Another very important discovery is the ability of certain bacteria to eliminate paraffin deposition around the producing well and in the tubulars. This is a welcome improvement for many producers who have considerable difficulty in controlling paraffin deposition.

This book was released on 1995 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-dimensional, three-phase, multiple-component numerical simulator was developed to investigate transport and growth of microorganisms in porous media and the impacts of microbial activities on oil recovery. The microbial activities modeled in this study included: (1) growth, retention, chemotaxis, and end product inhibition of growth, (2) the formation of metabolic products, and (3) the consumption of nutrients. Major mechanisms for microbial enhanced oil recovery (MEOR) processes were modeled as follows: (1) improvement in sweep efficiency of a displacement process due to in situ plugging of highly-permeable production zones by cell mass or due to improved mobility control achieved by increasing the viscosity of the displacing fluid with a biopolymer, and (2) solubilization and mobilization of residual oil in porous media due to the reduction of the interfacial tension between oleic and aqueous phases by the production of a biosurfactant. The numerical solutions for mathematical models involved two steps. The distributions of pressure and phase saturations were solved from continuity equations and Darcy flow velocities for the aqueous phase were computed. This was followed by the solution of convection-dispersion equations for individual components. Numerical solutions from the proposed model were compared to results obtained from analytical equations, commercial simulators, and laboratory experiments. The comparison indicated that the model accurately quantified microbial transport and metabolism in porous media, and predicted additional crude oil recovery due to microbial processes. 50 refs., 41 figs., 26 tabs.

This book was released on 2017-12-11 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Petroleum Biotechnology introduces the petroleum engineer to biotechnology, bringing together the various biotechnology methods that are applied to recovery, refining and remediation in the uses of petroleum and petroleum products. A significant amount of petroleum is undiscoverable in reservoirs today using conventional and secondary methods. This reference explains how microbial enhanced oil recovery is aiding to produce more economical and environmentally-friendly metabolic events that lead to improved oil recovery. Meanwhile, in the downstream side of the industry, petroleum refining operators are facing the highest levels of environmental regulations while struggling to process more of the heavier crude oils since conventional physical and chemical refining techniques may not be applicable to heavier crudes. This reference proposes to the engineer and refining manager the concepts of bio-refining applications to not only render heavier crudes as lighter crudes through microbial degradation, but also through biodenitrogenation, biodemetallization and biodesulfurization, making more petroleum derivatives purified and upgraded without the release of more pollutants. Equipped for both upstream and downstream to learn the basics, this book is a necessary primer for today’s petroleum engineer. Presents the fundamentals behind petroleum biotechnology for both upstream and downstream oil and gas operations Provides the latest technology in reservoir recovery using microbial enhanced oil recovery methods Helps readers gain insight into the current and future application of using biotechnology as a refining and fuel blending method for heavy oil and tar sands
