POE Finds Gas, Condensate at Akeh-1 Well in Sumatra's Batu Gajah PSC
Canada's Pan Orient Energy Corp. reported Tuesday that the Akeh-1 exploration well in the Batu Gajah production sharing contract (PSC), onshore Sumatra, Indonesia has completed the testing of four zones within the primary target Lower Talang Akar sandstone formation utilizing cased hole drill stem test (DST) procedures.
The average testing rates for DST 4 (5,314-5,324 feet) over a combined 12 hour and 37 minute flow period utilizing four different choke settings were:
- 6.8 million standard cubic feet per day (MMscf/d) of natural gas (2 percent CO2 or carbon dioxide)
- 269 barrels per day of API 60.1 degree condensate
- BS&W of 11.6 percent (emulsion comprised of 97 percent condensed water (chlorides 3545.3 milligrams per literor mg/l), 2 percent Sediment, and 1 percent Condensate (API 60.1 degrees))
A total of 3.7 MMscf of natural gas, 142.2 barrels of condensate and 25 barrels of condensed water was produced during the entire test period. There was no appreciable pressure decline observed over the duration of testing. Based on water salinity measurements, it is believed that the water observed during DST 4 is likely derived from water vapor within the gas cap. This will be confirmed through laboratory analysis of down hole gas samples that is currently underway.
The two deepest tests, DST 1 and DST 2, between the gross interval of 5,646 and 5,584 feet, recovered only formation water (chlorides 11,000-12,000 mg/l) while swabbing.
Approximately 5.3 barrels of API 55.2 degree oil, in addition to 109 barrels of formation water (chlorides 11,000 mg/l) and 25 barrels of load fluid was recovered on DST 3 over the interval 5524-5532 feet.
Updated, preliminary seismic mapping utilizing the Akeh-1 well tie and wireline pressure data indicates a maximum area of potential hydrocarbon charge at the top DST-4 sand level of approximately 2.5 square miles (6.5 square kilometers). 3D seismic mapping also indicates areas within the Batu Gajah PSC Akeh-1 prospect area where the DST-3 sand is approximately 65.6 feet (20 meters) structurally higher than encountered at the well location.
The next steps will be holding discussions with the Government of Indonesia in relation to having the Akeh structure "Released from Exploration Status". A successful release would allow the commencement of a "Pre-Plan of Development" study to determine the likelihood of the commerciality of the Akeh-1 discovery, which would be followed (if commerciality is deemed likely) by the compilation and submission of a Plan of Development. Pan Orient in its operations and activities in Indonesia is supervised and directed by SKKMigas.
