ASX-listed New Zealand Oil and Gas (NZOG) said Monday it has completed two drill stem tests (DSTs) at the Parit Minyak-3 (PM-3) exploration well, located in the Kisaran PSC onshore North Sumatra.
As previously reported, gas and condensate flowed to the surface during DST of the first zone at PM-3 exploration well. Flow testing of a gross open hole interval from 8520 feet (2598 meters) to 8760 feet (2671 meters) was completed on October 3. The well flowed at a rate of approximately 3 million scf/d gas and 90 barrels/day condensate on a 28/64" choke and with a flowing tubing head pressure (FTHP) of approximately 1000 psi.
The second DST was carried out in cased hole over two perforated intervals 8350 feet (2546 meters) to 8378 feet (2554 meters) and 8410 feet (2564 meters) to 8444 feet (2574 meters). The well flowed gas to surface at 12 thousand scf/d on 28/64" choke with a flowing tubing head pressure at FTHP of 100 psi and liquid influx to tubing was indicated. Liquid samples have been retrieved using wireline and are being analyzed.
Both tests were within Eocense/Oligocene Pematang sandstones. The current operation is retrieving the test string and preparing the well for suspension, NZOG said in a statement.
NZOG has a 22.5 percent stake in the joint venture through the share ownership of its subsidiary NZOG Asia Pty Ltd in Pacific Oil & Gas (North Sumatera ) Ltd. The Kisaran Joint Venture partners are Pacific Oil & Gas (Kisaran) Ltd (55% and operator) and Pacific Oil & Gas (Sumatera) Inc, a subsidiary of Bukit Energy Inc. (22.5%).
