Executive Summary

摘要

In this issue of SPE Res Eval & Eng, eight papers focus on the advancements in enhanced oil recovery, unconventional gas reservoirs, and reservoir characterization/simulation. The first paper in this category, A Pilot Carbon Dioxide Test, Hall-Gurney Field, Kansas, provides an extensive analysis of a pilot CO_2 test conducted in the Hall Gur-ney Field, Kansas. CO_2 was injected continuously in a single injector/three-producer pattern for nearly 19 months followed by 8 months of waterflooding. At the end of the pilot test, nearly 20,000 bbl of oil was produced, not only from the three producers in the pattern but also in other neighboring five wells.
