| Popis: | Summary The Wafra field is located in the partitioned neutral zone between Kuwait and Saudi Arabia. The field produces oil from the Ratawi oolite reservoir, which has been under production since 1956. Barriers to fluid movement have severely restricted aquifer support to the overlying carbonate grainstone reservoir, leading to production-induced pressure depletion and low recovery rates. Creative integration of three-dimensional seismic aspects, well log stratigraphy, and engineering analysis revealed an unexploited reservoir extension that is more open to aquifer pressure support. Wells drilled along this extension are expected to yield higher initial production rates and longer sustained production. The model was used to drill two successful step-out wells that have increased field production by over 12,000 BOPD. Eight of ten additional wells have now been drilled as a follow-up to this success. This paper reviews the case history with a focus on the multidisciplinary integration that led to opportunity identification and exploitation. |
