Owing to another delay, this time at no fault of its own, CGX Energy has revised the spud window for its Wei-1 prospect in the Corentyne Block to between December 2022 and late January 2023.
In its operational update on Wednesday, CGX explained that the “unforeseen challenges” were due to the exploration activities of the Noble Discoverer drilling platform.
The Noble Discover was scheduled to be in Trinidad and Tobago, for use by Shell, up to October 22, according to Noble’s Fleet Status Report.
“This situation is beyond the reasonable control of the Joint Venture. CGX and Frontera have communicated the revised spud window for the Wei-1 well to the Government of Guyana; expected to now be between December 2022 and late January 2023, subject to rig release by the third-party operator,” it said.
The rig was set to arrive in Guyana on October 22.
The Wei-1 exploration well is located approximately 14 kilometres northwest of the Kawa-1 exploration well in the Corentyne block, approximately 200 kilometres offshore from Georgetown.
The Wei-1 exploration well will be drilled in water depth of approximately 1,912 feet (583 metres) to an anticipated total depth of 20,500 feet (6,248 metres) and will target Campanian and Santonian aged stacked channels in a western channel complex in the northern section of the Corentyne block.
London-based energy intelligence firm, Westwood Global Energy, has called Wei-1 a ‘large, high-impact’ prospect and a ‘key well to watch’.
Following updated results on the Kawa-1 well, which noted the discovery of light oil and gas condensate, the partners had said that the chances of success at Wei-1 nearly doubled from 29% to 56%.
