CGX, Frontera JV make discovery offshore Guyana

CGX Energy Inc. and Frontera Energy Corp., the majority shareholder of CGX and joint venture partner of CGX in the Corentyne block offshore Guyana, made a discovery at the Kawa-1 well.

CGX Energy Inc. and Frontera Energy Corp., the majority shareholder of CGX and joint venture partner of CGX in the Corentyne block offshore Guyana, made a discovery at the Kawa-1 well.

The well encountered about 177 ft (54 m) of hydrocarbon-bearing reservoirs within Maastrichtian, Campanian, and Santonian horizons based on initial evaluation of logging while drilling data. These intervals are similar in age and can be correlated using regional seismic data to recent successes in Block 58 in Suriname and Stabroek block in Guyana, the companies said in a joint release Jan. 31.

The well also encountered hydrocarbon bearing sands in deeper strata (Coniacian or older) which will also be analyzed and could become the target of future appraisal opportunities. The net pay and fluid properties of the hydrocarbons across the shallow and deep reservoirs will now be confirmed with electric wireline logging and fluid sampling.

The well was drilled to a depth of 21,578 ft (6,578 m) and targeted the easternmost Campanian and Santonian channel-lobe complex on the northern section of the Corentyne block.

CGX is assessing opportunities to obtain additional financing to meet the costs of the drilling program.  

Second well

The joint venture anticipates spudding its second commitment well, Wei-1, in the northwestern part of the Corentyne block in second-half 2022 using the Maersk Discoverer semisubmersible mobile drilling rig.

The exploration well will target Campanian and Santonian aged stacked channels in the western fan complex in the northern section of the block.
