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.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Steam injection with added surface active chemicals is one of general EOR processes aimed to recover residual oil after primary production processes. It has been demonstrated that, after waterflooding, an oil swept area can be increased by steam surfactant flow due to the reduced steam override effect as well as reduced interfacial tension between oil and water in the formation. To investigate the ability to improve recovery of 20.5oAPI California heavy oil with steam surfactant injection, several experiments with a one-dimensional model were performed. Two experimental models with similar porous media, fluids, chemicals, as well as injection and production conditions, were applied. The first series of experiments were carried out in a vertical cylindrical injection cell with dimensions of 7.4 cm x 67 cm. The second part of experiment was conducted using a horizontal tube model with dimensions of 3.5 cm x 110.5 cm. The horizontal model with a smaller diameter than the vertical injection cell is less subject to channel formation and is therefore more applicable for the laboratory scale modeling of the one-dimensional steam injection process. Nonionic surfactant Triton X-100 was coinjected into the steam flow. For both series of experimental work with vertical and horizontal injection cells, the concentration of Triton X-100 surfactant solution used was chosen 3.0 wt%. The injection rates were set to inject the same 0.8 pore volumes of steam for the vertical model and 1.8 pore volumes of steam for horizontal model. The steam was injected at superheated conditions of 200oC and pressure of 100 psig. The liquid produced from the separator was sampled periodically and treated to determine oilcut and produced oil properties. The interfacial tension (IFT) of the produced oil and water were measured with an IFT meter and compared to that for the original oil. The experimental study demonstrated that the average incremental oil recovery with steam surfactant flood is 7 % of the original oil-in-place above that with pure steam injection.

Available in PDF, EPUB and Kindle. Book excerpt: This experimental investigation was carried out to develop a foam treatment for possible field application in a steam flood operation. The study evaluated several available surfactants to select the most promising and provided data on the effect of several process parameters for the selected surfactant. Six different surfactants, representing a cross section of temperature stable surfactants currently in the market, were evaluated in Ottawa sand cores. The increase in pressure drop across the core resulting from injection of the foaming surfactant with steam into the core containing steam flood residual oil was measured. The extent of surfactant losses due to adsorption and thermal degradation in the field were also considered. The effects of concentration, flow rates, steam quality and non-condensable gas were examined using the selected surfactant.

Available in PDF, EPUB and Kindle. Book excerpt: Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. But only about 10 percent of a reservoir's original oil in place is typically produced during primary recovery. Secondary recovery techniques to the field's productive life generally by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place. In the past two decades, major oil companies and research organizations have conducted extensive theoretical and laboratory EOR (enhanced oil recovery) researches, to include validating pilot and field trials relevant to much needed domestic commercial application, while western countries had terminated such endeavours almost completely due to low oil prices. In recent years, oil demand has soared and now these operations have become more desirable. This book is about the recent developments in the area as well as the technology for enhancing oil recovery. The book provides important case studies related to over one hundred EOR pilot and field applications in a variety of oil fields. These case studies focus on practical problems, underlying theoretical and modelling methods, operational parameters (e.g., injected chemical concentration, slug sizes, flooding schemes and well spacing), solutions and sensitivity studies, and performance optimization strategies. The book strikes an ideal balance between theory and practice, and would be invaluable to academicians and oil company practitioners alike. Updated chemical EOR fundamentals providing clear picture of fundamental concepts Practical cases with problems and solutions providing practical analogues and experiences Actual data regarding ranges of operation parameters providing initial design parameters Step-by-step calculation examples providing practical engineers with convenient procedures
