Available in PDF, EPUB and Kindle. Book excerpt: As a result of water flood studies made on a long unconsolidated core consisting of a pack of glass spheres, it has been found that break through recovery decreases by about 16 per cent as the wettability of the pack is changed from preferentially water wet to preferentially oil wet. This change in wettability has been brought about by treating the glass spheres with dilute solutions of Dri-film in benzene. The ultimate recovery has also been found to decrease as the oil wetness of the porous medium increases. The degree of wettability of the porous medium has been estimated by carrying out contact angle measurements in glass capillary tubes. An attempt has been made to establish the same wetting conditions in the capillary tubes as in the porous medium. This has been done by keeping the ratio of the volume of the treating liquid to the surface area treated, approximately the same in both.

This book was released on 2020 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wettability reversal during the displacement processes encountered in hydrocarbon reservoirs has gained significant attention in recent years owing to its critical role in the success/failure of water-based enhanced oil recovery (EOR) schemes. Regardless of different designations used for these technologies, e.g., low-salinity waterflooding (LSWF), smart water injection, or engineered water injection, manipulating the ionic compositions and concentrations of the aqueous solutions to trigger the wettability reversal process is the shared objective. Despite the encouraging application potentials, the mechanisms that govern the wettability reversal and how it affects the displacement efficiency are still poorly understood, particularly in oil-wet carbonates. Therefore, in this work, multi-scale experiments were carefully designed and conducted to probe the impacts of rock wettability and its reversal, induced through brine chemistry manipulation, on oil recovery performance. We first investigated the adsorption-controlled calcite substrate wettability using a HPHT interfacial tension/contact angle measurement apparatus. The results were then further examined in natural rock samples through miniature core-flooding experiments. A high-resolution X-ray micro-CT scanner was used with a multiphase fluid delivery system to conduct the flow tests. Prior to each waterflooding experiment, an equilibrium wettability state was established in the core sample. This study reveals that wettability reversal, caused by adsorption/desorption of the polar components present in crude oil, is the principal factor responsible for the changes in oil recovery trend during LSWF. Dynamic contact angles measured on calcite substrates indicated that adsorption of the polar components controlled the surface wettability. Higher concentrations of Ca2+/SO42− can facilitate/obstruct the adsorption of polar components thus increase/decrease the dynamic contact angle values. A similar wetting strength sensitivity to the changes in aqueous phase composition was observed in miniature core samples when the in-situ contact angle measurement technique was used to characterize wettability. Using a dynamic aging process, weakly to strongly oil-wet conditions were established in samples aged with high-salinity brine, whereas low-salinity brine or brine with a higher concentration of sulfate ions created a more heterogeneous wettability. Different equilibrium wetting conditions thus produced various oil recovery trends. Moreover, two distinct displacement mechanisms, i.e., piston-like invasion and wetting oil layer drainage, were identified, through image analysis, to play key roles in affecting the recovery trends. Wettability reversal improved the efficiency of water-displacing-oil events by enhancing the frequency/strength of both mechanisms, while their relative contributions varied from one wettability case to another. These findings provide in-situ experimental evidence that demonstrates a direct link between the composition of the engineering injection brine and enhanced sweep efficiency at the pore scale in oil-wet carbonate samples.

Available in PDF, EPUB and Kindle. Book excerpt: It is well-known that colloid and interface science and petroleum production are inextricably linked. Whether in the reservoir, with its porous structure, or during recovery, crude oil is intimately associated with rock surfaces and with water, often in the form of emulsions. This situation leads to highly complex systems, comprising multiple colloids and interfaces, which require to be optimized if oil is to be recovered efficiently, both in terms of economic cost and with due concern for the environment. This book contains a compilation of contemporary research topics which illustrate various aspects of the importance of colloids and interfaces in crude oil recovery through modifying conditions between the rock, crude oil, and water in the reservoir, in order to achieve improved oil recovery. The specific topics covered relate both to conventional oils, in which waterflooding is the most common secondary and tertiary means of recovery, and to non-conventional heavy oil and natural bitumen, which require thermal recovery methods, owing to their high viscosity.

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. About the Authors Patrizio Raffa is Assistant Professor at the University of Groningen.

This book was released on 2006 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Oil recovery efficiency is influenced by a myriad of interacting variables such as pore geometry, wettability, rock mineralogy, brine salinity, oil composition, etc. Reservoir wettability is known to have very significant influence on pore scale displacement and hence is a strong determinant of the final residual oil saturation. Recent studies have indicated the improved oil recovery potential of low salinity brine injection. Though the reason for this reported increase is still unclear, it is speculated that it may be due to wettability changes. In this work, coreflood studies were carried out to determine the recovery benefits of low salinity waterflood over high salinity waterflood and the role of wettability in any observed recovery benefit. Two sets of coreflood experiments were conducted; the first set examined the EOR potential of low salinity floods in tertiary oil recovery processes while the second set examined the secondary oil recovery potential of low salinity floods. Changes in residual oil saturation with variation in wettability and brine salinity were monitored. All the coreflood tests consistently showed an increase in produced oil and water-wetness with decrease in brine salinity and increase in brine temperature"--Leaf iii.
