The well was drilled to 6,417ft TVD to test Miocene and Upper Oligocene targets in an upthrown block west of the discoveries in the A-01 well.
The A-04 well encountered 22ft of net pay in the Miocene with average porosity of 29%.
The reservoir is in a fault block separate from the A-01 well and the company estimates that it contains approximately six million barrels of oil in place.
The A-04 well also encountered 11ft of net sand with shows in a deeper Miocene section with 22% average porosity and 10ft of net sand with shows in the Upper Oligocene with 25% porosity.
The productivity of the deeper Miocene and Upper Oligocene zones will not be determined until they can be flow tested, which is expected to begin in mid-May, the company said.
