CGX Energy Inc. spudded the Kawa-1 exploration well, offshore Guyana, on Aug. 22. The well is expected to reach total depth in first-half December.
Kawa-1 well lies in the northeast quadrant of the Corentyne block, some 200 km offshore from Georgetown. Water depth is about 355 m and the expected total depth of the Kawa-1 well is 6,685 m.
The well targets light oil in combination structural-stratigraphic traps in large Santonian and Campanian slope fan complexes. The primary target is a Santonian sand with updip and lateral pinchout of the reservoir, as well as counter-regional dip and structural closure. The well also is expected to penetrate secondary objectives in a shallower Campanian sand and a deeper Santonian sand with the expectation of targeting additional hydrocarbon potential. The stacked targets in Kawa-1 are considered analogous to the discoveries immediately adjacent to the Corentyne block, in Block 58 in Suriname.
Additionally, Kawa-1 well is expected to de-risk other prospects on the block which also have stacked reservoirs and similar structural geometries, CGX said in an Aug. 23 release. Proximity of the Corentyne block to the Cretaceous Berbice Canyon sediment source is interpreted to have concentrated sandstone reservoirs in the North Corentyne area, the company continued, and channelized, stacked internal fan geometries evident on 3D seismic are indicative of thick, stacked, coarser-grained sand reservoirs.
The joint venture exercised its option to drill a second well with Maersk through use of Maersk Discoverer.
Frontera Energy is joint venture partner in the 1.125-million net acre block.
