InterOil announced that gas has flowed from its Antelope 1 well confirming hydrocarbons in the Antelope Reef. The top of the reservoir was intersected at 5,735 feet (1,748 meters) with gas encountered at that same depth. Drilling ahead is continuing at 5,892 feet (1,796 meters) with an underbalanced mud system with gas production averaging 2-3 MMcfd whilst drilling with full returns and approximately 3,400 psi of back pressure on the formation. Rates up to 15 MMcfd have been achieved while circulating out gas kicks.
The forward program is to drill ahead to a planned total depth of 2,500 meters and test the well, which is targeting the Puri and Mendi, and Antelope reef limestone.
"We are extremely pleased with the early confirmation of gas and the gas flow results from the Antelope-1 well," said Phil Mulacek, Chief Executive Officer. "The well continues to reflect our expectations for gas volumes in the Antelope field. What we have seen to date is expected to have a positive effect on the evaluation of gas volumes in the Antelope structure currently being conducted by independent experts."
