Chevron said that the appraisal well confirmed the same pay intervals of the previously announced discovery and sidetrack wells. The well found the main pay sand full of oil to the base.
Operated by a Chevron subsidiary, the appraisal well reached a measured depth of 25,113 feet at a location deeper than the previous wells. Chevron is evaluating a range of production development options for the Big Foot prospect.
Chevron owns a 60% working interest in Big Foot. Its partners include Norwegian oil and gas firm StatoilHydro with a 27.5% stake and Shell Gulf of Mexico with a 12.5% interest.
