... methods, most of which are WAG processes[2]. As for the WAG process, water and gas, such as CO2, can be injected either simultaneously or alternatively. The water is used to control the mobility of the gas for achieving higher macroscopic sweep efficiency, while gas injection, especially miscible gas...

... to be implemented. The objective of this work is to quantify the effects of directional permeability anisotropy, using Sweep Efficiency and Net Present Value (NPV) as study parameters, on the production performance during a waterflooding under fracturing conditions, in which the injectivity loss is represented...

... PETROLEUM SOCIETY CANADIAN INSTITUTE OF MINING, METALLURGY & PETROLEUM 2process is designed to improve the continuous gas injection EOR method, mainly by reducing gas mobility and thereby increasing sweep efficiency in the reservoir. The main objective of modern reservoir management is to achieve maximum...

... of the project and illustrates the effectiveness of CO 2 and water injection in terms of oil recovery and CO 2 utilization. This paper also demonstrates the importance of reservoir monitoring to optimize sweep efficiency, as the patterns become mature. Even after 19 years since the initial pilot program...

..., arbitrarily using an exponential decline approach (log(q o ) versus time assumed to be linear) for water drive, solution gas drive, and gravity drainage systems is neither technically nor empirically correct. Use of exponential decline during periods of increasing volumetric sweep efficiency will generally...

... was investigated by using a computer program based on the estimation of volume-burned. The program was run by changing areal sweep efficiency, pattern size and air injection rate to achieve the optimum conditions. It has been shown that the oil recovery can be increased from 1.4 % to 33.4 % of OOIP through...
