Field observations have shown that interference between wells caused by connected fractures commonly exists in unconventional reservoirs. The well effect and conformance issues could lead to minimal enhanced oil recovery response (EOR) actual operations if they are not properly controlled. A series of data analysis, modeling, experimental activities were performed this study investigate the gas...

Low Salinity Water (LSW) incorporates in surfactant Enhanced Oil Recovery (EOR) as a pre-flush is common practice aiming to reduce the formation salinity, which affects adsorption. However, field implementation, adsorption of unavoidable, so creating scheme that detaches trapped equally essential. In this study, LSW was candidate enhance desorption surfactant. solely formulated from NaCl (1 wt....

Chemical enhanced oil recovery (EOR) methods are alternatives to increase production in mature reservoirs. However, the presence of EOR chemicals produced water may impact separation gas-water systems platforms. The present work aims evaluate polymers, surfactants, inorganic salts, and their interactions on gas holdup a 32.1-cm-diameter semi-batch bubble column over range superficial velocities...

Abstract Diminishing hydrocarbon reserves in oil reservoirs and the need to sustain continuous production have prompted researchers further investigate Enhanced Oil Recovery (EOR) techniques. Researchers also test run these processes before EOR fluid injection into reservoir maximise whilst minimising damage loss. This study aims simulate displacement during of two different types fluid, namely...

Assessment of the potential of a polymer flood for mobility control requires an accurate model on the viscosities of displacement fluids involved in the process. Because most polymers used in EOR exhibit shear-thinning behavior, the effective viscosity of a polymer solution is a highly nonlinear function of shear rate. A reservoir simulator including the model for the shear-rate dependence of v...

This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with ident...

• The effect of electrical heating on oil recovery in carbonate rocks was investigated. Electrical increased from water-wet and oil-wet samples. causes a reduction contact angle surface tension. makes imbibition faster, improving early time production. Renewable powered CCS can give low emission yields depleted wells. New approaches for enhanced (EOR) with reduced environmental footprint are re...

One of the tertiary methods for enhanced oil recovery (EOR) is the injection of chemicals into oil reservoirs, and surface active agents (surfactants) are among the most used chemicals. Surfactants lead to increased oil production by decreasing interfacial tension (IFT) between oil and the injected water and to the wettability alteration of the oil reservoir rock. Since surfactants are predomin...
