This interval contains target horizons in the Jurassic Mus and Butmah formations and the Triassic Kurra Chine formation.
The well flowed at a stabilized rate of about 4.6 million standard cubic feet of gas and 7,280 barrels of formation water per day during a 12-hour flow period through a 1.5 inch choke with a wellhead pressure of 470 pounds per square inch.
About 74% of the produced gas was hydrocarbon gas with the remainder comprising 24% hydrogen sulphide and 2% carbon dioxide.
A wireline logging operation was attempted to identify the contribution from individual zones within the open hole section but was unsuccessful due to mechanical restrictions within the flow testing equipment, the company said.
No further flow testing is planned in the open hole section of the well and this section is being isolated with cement plugs.
The joint venture partnership has elected, based on gas shows while drilling, to conduct two cased hole flow tests: the first across a 100m interval within the Jurassic aged Sargelu formation and the second across a 100m interval within the Cretaceous aged Kometan formation.
Sterling Eneregy holds a 53.33% working interest in the Sangaw North block and is its operator.
