  • Horizontal drilling increases injectivity and recovery: An update

    S. Robinowitz and R. Westermark

    Grand Resources is applying horizontal waterflooding in various Midcontinent fields. The company is quickly learning how to apply low-cost horizontal drilling for injectors and producers to optimize production. Further developed with US Department of Energy (DOE) funding, this technology has revived oil production from an abandoned oil field on Osage Indian tribal lands, in other fields in northeastern Oklahoma and in a shallow field in southeast Kansas. Grand focused first on applying horizontal waterflooding in the 25–50 md permeability portion of the shallow Bartlesville formation. We published this story in this space in the March 2004 issue. Results from the first field, Wolco, were not available at that time. This article provides results on that field and other fields drilled since our 2004 report.
