Corvina Field CX-15 Platform
The CX15-1D well was completed in the Zorritos formation and continues to be evaluated. Four prospective intervals have been identified in the oil zone, of which one 40 foot interval is now open. This opened interval has averaged approximately 330 bopd over the past ten days, and over the last 24 hours it has averaged approximately 500 bopd, naturally flowing with no water production and normal gas oil ratio. Other perforated intervals will be opened individually to assess optimal well productivity. The CX15-1D well was drilled near the CX11-21XD to a measured depth of approximately 7,900 feet.
