... Abstract This paper discusses the design and implementation of a Single Well Chemical Tracer Test (SWCTT) to evaluate the efficacy of a lab-optimized surfactant-polymer formulation for the Raudhatain Lower Burgan (RALB) reservoir in North Kuwait. A SWCTT was designed upon completing extensive...

... Abstract Polymer-surfactant mixtures in aqueous solutions present unique rheological and interfacial properties that promote their applications in chemical flooding. The objective of this study is to investigate the interaction between anionic polyacrylamides and cationic surfactants...

... water. Use of an inverter surfactant accelerates the inversion of the polymer emulsion. For this study two highly efficient inverter surfactants at different price level were selected and their impact on the performance of an acrylamide-based emulsion copolymer was investigated. Polymer solutions...

... Abstract An inverted 5-spot Alkaline Surfactant Polymer (ASP) pilot is planned for a giant sandstone reservoir in North Kuwait. Despite the development of a robust lab-optimized ASP formulation at reservoir temperature (90°C) and the execution of a successful Single Well Chemical Tracer Test...

... Abstract This paper discusses static and dynamic adsorption experiments to evaluate surfactant and alkali consumption as well as polymer injectivity to guide well perforation design for an Alkaline Surfactant Polymer (ASP) pilot in a giant clastic reservoir in Kuwait. Alkali and surfactant...

... challenge by increasing the gas apparent viscosity. Surface active agents such as surfactants are usually used to generate foams. However, the long-term stability of the surfactants is challenging. The synergistic effect of surfactants and nanoparticles may offer a novel technique to solve the foam...

... Abstract The potential of CEOR application in mature oil fields can be investigated using sector models of an appropriate boundary conditions. In this paper, we present an evaluation of feasibility study of surfactant and estimation of the incremental recoverable oil in a mature Libyan oil...

... sweep with modified brines, given the viscosity and density differences relative to formation brine, requires careful assessment. New polymers and surfactants are expanding the technical window of opportunity, currently chemical EOR in these environments is still commercially challenged. EOR technology...

... the oil and water phases to avoid using chemical demulsifiers. The separated oil and water phases were physically and chemically characterized and the oil-water interfacial tension was determined using pendant drop method at a temperature range between 20 to 50 o C. The effects of solvent, surfactant...

... challenge; however, is the stability of the generated foam when it contacts the oil. Foam boosters, which are generally costly surfactants, have been co-injected together with the main foaming surfactant to create stable foams in the presence oil. Similar to surfactants, particles can also accumulate...

... Abstract This paper describes a series of experiments that used X-ray computer tomography (CT) to visualize the mobilization of remaining oil by Alkaline Surfactant (AS) and Alkaline Surfactant Polymer (ASP) flooding after conventional waterflooding. The experiments were conducted in cores...

... gravity override or viscous fingering ( Friedmann et al. 1994 ). To create and propagate stable foam, a surfactant must be added to the liquid phase of the steam. In addition, a small amount of non-condensable gas may be added to the steam. The role of this non-condensable gas is to stabilize the collapse...

... Abstract Foam enhanced oil recovery techniques involving super critical CO 2 with surfactants are becoming popular these days due to the ability of foam to appreciably overcome problems like gravity override and viscous fingering. Foam lowers the mobility of the injected fluid consequently...
