Stabilised flow rates were obtained over several five-hour intervals and were measured through a 72/64” choke with the flow constrained by tubing.
The well reached a total depth of 2,090 meters (6,856 feet) MDRT.
InterOil chief executive Dr Michael Hession said the result was pleasing and underscored the region’s prospectivity.
“We are excited by the well results and the enhanced development optionality that Triceratops gas can provide,” he said.
The Antelope-4 side track appraisal well in PRL 15 has intersected the reservoir 36 meters (118 feet) higher than the original Antelope-4 penetration.
The well is being prepared for casing before drilling through the reservoir.
