Book excerpt: Written by foremost experts in the field, and formulated with attention to classroom use for advanced studies in reservoir characterization and processes, this book reviews and summarises state-of-the-art progress in the field of enhanced oil recovery (EOR). All of the available techniques: alkaline flooding; surfactant flooding; carbon dioxide flooding; steam flooding; in-situ combustion; gas injection; miscible flooding; microbial recovery; and polymer flooding are discussed and compared. Together with Volume I, it presents a complete text on enhanced recovery technology and, hence, is an almost indispensible reference text.This second volume compliments the first by presenting as complete an analysis as possible of current oilfield theory and technology, for accomplishment of maximum production of oil. Many different processes have been developed and field tested for enhancement of oil recovery. The emerging philosophy is that no single process is applicable to all petroleum reservoirs. Each must be treated as unique, and carefully evaluated for characteristics that are amenable to one or two of the proven technologies of EOR. This book will aid the engineer in field evaluation and selection of the best EOR technology for a given oilfield. Even the emerging technology of microbial applications to enhance oil recovery are reviewed and explained in terms that are easily understood by field engineers.The book is presented in a manner suitable for graduate studies. The only addition required of teachers is to supply example problems for class work. An appendix includes a reservoir mathematic model and program for general application that can also be used for teaching.

Download or read book Comprehensive Experimental Study on Foam Flooding for Enhancing Heavy Oil Recovery written by Jing Zhao and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, thermal method, such as steam injection and in-situ combustion are the best for recovering heavy oil. However, some reservoirs in Canada and the United States with ultra thin oil formations saturated with lower viscous heavy oil (50~200 cp), chemical flooding is more attractive compared with conventional thermal methods. This study is aimed to explore the effectiveness and potential application of foam flooding for enhancing moderately viscous oil recovery. The effects of surfactant type and concentration on surfactant properties were examined in terms of bulk foam ability and foam stability by the Ross-miles method and Warning blender method. Foam stability in the presence of experiment heavy oil was determined on the basis of a mechanistic understanding of foam propagation in porous media, combined with "Pseudoemulsion-film model" theory. The effects of foam quality and flow rate on foam mobility were determined by performing a series of steady-state foam flow experiments in oil-free sandstone porous media. Oil displacement experiments were conducted to determine the effectiveness of immiscible foam as a tertiary recovery method in recovering heavy oil and to make a comprehensive evaluation of oil displacement efficiency of foam generated by different surfactants. Mobility Reduction Factor (MRF) in the presence or absence of oil were determined to reveal the destabilize effect of oil on foam stability in porous media and investigate the sensitive degree of different types of foam to oil. Results show anionic surfactants had the best comprehensive foaming ability, followed by nonionic, cationic surfactants. The optimum foaming concentration was found to be 1.0 wt%. To generate stabilized foam, BIO-TERGE AS-40, STEPANTEX VT-90, Triton X-100 were selected as representatives of anionic, nonionic, and cationic surfactants, respectively. Co-injection of CO2/foaming agent was manifested as a reasonable injection strategy, and the highest recovery factor (RF) was obtained at 80% foam quality with the flowrate of 2.5 cm3/min (at ambient condition). VT-90 foam, as a cationic surfactant, surprisingly presented the highest resistance to flow compared with foam generated by other two surfactants at the same foam quality and gas/liquid flow velocities. Results of this study showed that foam flooding can be used as an effective tertiary method for enhancing heavy oil recovery. One order decrease in MRFs of the three tested surfactants after interacting with water-flood residual oil proved that experiment heavy oil undoubtedly destabilizes foam texture. VT-90 foam, again exhibited extraordinary foam strength with oil despite its poor bulk foam ability. The ultimate oil recovery of as high as 73% of residual oil in place (ROIP) by VT-90 foam coincides with its lowest sensitive degree to heavy oil. It is speculated that, commercial microemulsions, such as STEPANTEX VT-90 solution, have the potential to recover more oil by emulsifying oil droplets in the Plateau borders and transporting them with bubbles.

This book was released on 2018 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal enhanced oil recovery techniques have been considered as the best approach to produce heavy oil; however, hybrid methods, which are combinations of different oil recovery methods, reveal more promise in enhancing oil production from heavy and viscose reservoirs. In this research, we investigate improving recovery from heavy oil reservoirs, considering steam foam method to control the mobility of steam and oil in such reservoirs, and delivering proper amount of heat to reservoir in order to reduce oil viscosity. In this thesis, a compositional K-value based reservoir simulator, CMG-STARS, was used to build simulation models for all case studies. Steam table is used to calculate the phase change during steam injection and to capture latent heat effect on energy balance and mass balance equations. CMG-STARS empirical foam model is used to capture mobility of steam in the presence of surfactant. Simulation models are tuned with experimental core data and field history data. Simulation results illustrated that a considerable increase in oil recovery is obtained when steam foam is used. It is also observed that foam parameters, which was used in modeling, affects oil recovery, reservoir average temperature, average pressure and gas saturation. Optimized foam parameters were determined considering oil recovery, average reservoir temperature, and average reservoir pressure. Finally, simulations revealed that field and simulation results were in good agreement with field data, and that steam foam oil recovery method has the potential to become a promising oil recovery method for heavy oil reservoirs.

This book was released on 2020 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various enhanced oil recovery methods (EOR) suffer from poor sweep efficiency due to viscous fingering, channeling, and gravity segregation issues. The water-alternating-gas method (WAG) used in the Al-Shaheen’s Shuaiba reservoir has encountered similar problems, whereby injected gas preferentially flows into higher permeability zones and sweep efficiency is impacted. The goal of this research work was to develop an effective, and economically viable foam system that can utilize waste gas in the Al-Shaheen reservoir as a mobility control solution. This research focused on an optimized surfactant formulation that can generate foam with methane gas at the reservoir conditions in the presence of oil and an oil wet/mixed wet rock. The formulation was tested in water wet and oil wet core flood experiments. Enhancements to the formulation were tested and their improvement to the foam strength was quantified. An anionic surfactant group alkyl-polyglycoside (APG) was first chosen through screening experiments. The bulk foam stability was then evaluated with and without oil presence and showed APG-5 as the best among the APGs. Its adsorption to carbonate Estaillades limestone was estimated around 2.5 mg/g of rock at 55 °C and the reservoir brine salinity of 144,000 ppm. Core flood experiments revealed that a concentration of 3500 ppm is required to achieve strong foam. The foam rheology of APG-5 and methane gas was found to be shear thinning. The ideal foam quality resulting in the strongest foam was found to be between 30 and 50 %. The impact of oil on the APG-5 foam was studied, and found to produce effective foam in presence of residual oil in water wet cores and oil wet cores, with mobility reduction factor (MRF) values of 28 for the former and 24 for the latter. It was also shown through mobile oil experiments that foam can develop even in presence of mobile oil. Oil wet environments were shown to have weaker foams. The use of a wettability altering agent TGT-1 improved the foam propagation and steady state strength. MRF values of ~ 47 were achieved, an increase of 150%. A foam booster (Lauryl Betaine) was tested and found to enhance the propagation and steady state strength of the foam with MRF values of 52. Combining the wettability alteration, and foam boosting in a final formulation achieved and MRF of 85
