CGX Energy has commenced drilling of the Kawa-1 well site in the Corentyne Block offshore Guyana.
According to a notice by the Maritime Administration Department (MARAD), exploration drilling operations commenced on July 2 at the Kawa-1 well site situated 90 nautical miles offshore Guyana and covers an area of 4.7 square nautical miles,
The mobile offshore drilling unit (MODU) Maersk Discoverer is conducting drilling activities at the well-site.
CGX stated that the Kawa-1 exploration well on the Corentyne block is currently expected to be drilled to a depth of approximately 6,500 metres. The well is expected to be spudded in the second half of 2021. The primary target is a Santonian age, stratigraphic trap, interpreted to be analogous to the discoveries immediately to the east on Block 58 in Suriname.
Approximately US$90 million would be spent on its Guyana exploration programme in 2021 but it is unclear how much is allocated for the drilling of the Kawa-1 well as preparatory work for the Makarapan-1 exploration well on the Demerara block which is also expected to be spudded this year, is also ongoing. According to CGX, exploration continues to advance and is currently expected to be drilled to a total depth of approximately 3,500 metres.
Additional prospects and leads on the northern portion of the Corentyne, and also on the Demerara Block have been identified and are being matured by the company.
CGX pointed out that basin-wide studies, which include hydrocarbon generation and migration analysis and biostratigraphic studies, are underway and will be incorporated into the exploration efforts to further refine the projects and reduce exploration risk.
In February, Frontera Energy Corpora-tion disclosed that a total of 32 drill prospects were identified in the offshore Corentyne and Demerara blocks.
Frontera holds a direct working interest of 33.3% in both the offshore Corentyne and Demerara blocks, and together with CGX, shares ownership of 73.8%, resulting in a total consolidated working interest of 82.6% in the blocks.
The two partners commonly referred to as the “Joint Venture”, contracted McDaniel & Associates Consultants Ltd to conduct a resource evaluation of their concessions in the Guyana-Suriname basin.
Frontera announced that McDaniel had identified 27 prospects in the Corentyne block and five in the Demerara block. A statement by the company noted that 64% of the fluid content considered for the prospects, was comprised of oil, 28% natural gas, and the remaining 8% as condensates.
CGX has drilled a number of wells here but has not struck oil in commercial quantities.
