Efficiency Estimation

Nowadays the share of hard-to-recover reserves is growing, and to maintain oil production on necessarily level, we need to involve hard-to-recover reserves or to increase oil production efficiency on a brownfields due to enhanced oil recovery. The efficiency of enhanced oil recovery can be estimated by oil saturation reduction. Single-well-chemical-tracer-test (SWCTT) is increasingly used to estimate oil saturation before and after enhanced oil recovery application. To interpret results of SWCTT, reservoir simulation is recommended. Oil saturation has been calculated by SWCTT interpretation with use of reservoir simulator (CMG STARS). Distribution constants has been corrected due to results of real core sample model, and core tests has been successfully simulated. Obtained values of oil saturation corresponds with real oil saturation of samples. Thus, SWCTT as a method of oil saturation estimation shows good results. This method is promising for enhanced oil recovery efficiency estimation.

Alkaline Surfactant Polymer

Summary A tertiary alkaline/surfactant/polymer (ASP) pilot flood was implemented during 2010 in the Illinois basin of the US, and is continuing currently. With initial discovery of the Bridgeport sandstone formation in the early 1900s and more than 60 years of waterflooding, the pilot was designed to demonstrate that ASP flooding could produce sufficient quantities of incremental oil to sanction a commercial project. Laboratory experiments, including corefloods, were performed to determine the optimal chemical formulation for the pilot and to provide essential parameters for a numerical-simulation model. Polymer-injectivity tests, single well chemical tracer tests (SWCTTs), and an interwell-tracer-test (IWTT) program were all performed to prepare for and support a full interpretation of the pilot results. A field laboratory was run through the duration of the pilot to monitor the quality of the injection and production fluids, which turned out to be critical to the success of the pilot. We present the results and interpretation of the ASP pilot to date, the challenges faced during the project, and the lessons learned from the field perspective.
