BAKERSFIELD, CA.–Accurately delineating reservoir fluid dynamics has long been a dream for the oil and gas industry. Improving this capability is more urgent than ever, especially in mature oil provinces such as the United States, where the bulk of production still comes from fields that are decades old. A lack of access to some of the biggest undrilled U.S. prospects has resulted in a lagging oil discovery rate, and it has fallen to secondary and tertiary recovery projects to keep the nation’s oil production from declining.
