A Laboratory and Field Evaluation of the CO2 Huff ’n’ Puff Process for Light-Oil Recovery

Abstract

Summary Cyclic CO2 injection for enhanced recovery of light crude oil is investigated. Results from watered-out Berea corefloods and 14 field tests demonstrate that first and second cycles recover waterflood residual oil. Factors that may improve performance include larger reservoir slug volume, soak period, thicker interval, and lower prior water cut.
