A drill stem test (DST) conducted between 3,138ft – 3,350ft sub-surface (212 foot gross pay interval, 105.5 foot net pay interval), flowed dry natural gas and no water from the Cienaga de Oro Formation (CDO) at a measured rate of 8.4MMcf/d, through a 48/64th inch choke with surface pressure at 579psi.
The company has estimated that the calculated absolute open flow (AOF) rate of the well to be 12.5MMcf/d of natural gas, based on the available data from the test. This AOF rate will be reviewed and updated once downhole gauges are recovered from the well and pressure data can be further analyzed, the company said.
Current plans are to suspend the well until a permit to conduct a long-term test is received. Evaluations of deeper pay intervals drilled in the Brillante SE-1X well will be conducted in subsequent appraisal wells.
