Tullow Oil PLC said subsidiary Tullow Guyana BV made a significant oil discovery through an exploration well in the Orinduik license offshore Guyana, according to an Aug. 12 news release.
The Jethro-1 well, drilled by the Stena Forth drillship, reached a total depth of 4,400 meters in water depths of 1,350 meters and encountered 55 meters of net oil pay. The company said the discovery supports a recoverable oil resource estimate that exceeds its pre-drill forecast and confirms that the prolific petroleum system in the neighboring Stabroek block, operated by Exxon Mobil Corp., extends onto the Orinduik block.
In a separate Aug. 12 release, Africa Oil Corp. said Stena Forth will move on to drill the Joe-1 well and is expected to spud in mid-August.
Tullow Guyana operates the Orinduik block license with a 60% interest. Total SA unit Total EP Guyana BV and Eco (Atlantic) Oil & Gas Ltd. own the remaining 25% and 15% stakes, respectively. Africa Oil holds an 18.8% stake in Eco (Atlantic) Oil & Gas.
