Tap Oil Encounters Gas in Marwar-1 Oil Well

Tap Oil has announced that gas has been encountered in Marwar-1 well in Block M, onshore Brunei Darussalam.

The firm drilled the Mawar-1 well to its total depth of 1,292m and completed wireline logging, pressure and fluid sampling.

Preliminary interpretation of results show that Mawar-1 encountered gas in primary objective Ridan Sandstone of up to 25m of Ridan reservoir at a depth of 1,005m MD.

Tap chief executive officer Peter Stickland said it is “disappointing” that the primary objective Ridan formation appears to be gas charged at this location.

“Further studies will be undertaken to determine if there is potential for an oil leg down dip of the gas in Mawar-1,” Stickland said.

A deeper secondary objective Rampayoh Series also had good hydrocarbon indications in an inter-bedded sand-shale sequence.

At present, casing is being run across the hydrocarbon zones before suspending Mawar-1.

Block M spread over an area of about 3,011km² in the Baram Delta Basin contains the Belait oil and gas field.
