Executive Summary

 

The Kavango Basin formed through a combination of rifting and shearing, most likely in the Permian to Triassic period. According to ReconAfrica and studies on the basin, the basin represents one of the largest onshore undeveloped hydrocarbon basins in the world. Based on a tight grid aeromagnetic survey, up to 30,000 feet of sedimentary fill has been estimated. Up to 6,000 feet of which could be a Permian age petroleum system. According to ReconAfrica, extrapolation from a control well indicates that source rocks should be present in the lower intervals of the Permian. Modelling has shown that this potential source rock is overlain by classic tilted fault block traps, which have provided the basis for conventional traps in other hydrocarbon rich basins. Geochemical and other studies have estimated that the basin could have significant in place volumes of hydrocarbons, further details of which can be found on ReconAfrica’s website (www.reconafrica.com).

 

A number of the characteristics identified in the basin to date indicate that the basin could have the right combination of factors to have a working petroleum system. Further exploration is required to determine if this is the case, which ReconAfrica is scheduled to undertake in Q1 2021 (2D seismic campaign & 3 exploration wells). However, should that exploration be successful, it is useful to consider how exploration and development has progressed in other basins that have some of the same characteristics as the Kavango Basin. Wood Mackenzie undertook a process to identify a number of these basins. The selected basins are shown in the table below alongside their rationale for inclusion.

Conclusion

 

From the characteristics identified in the Kavango Basin, Wood Mackenzie identified three analogous basins, and evaluated their evolution. The basins evaluated included the Midland Basin, the Southern North Sea Basin and the Doba Basin. Key value and reserve metrics were provided, as well as production profiles over the basins’ life. Should exploration undertaken by ReconAfrica in the Kavango Basin be successful, the details of how exploration and development has progressed in these three basins provides a useful benchmark as to what basin evolution may look like.

  Awilco LNG ASA is pleased to announce that the 2013-built 156,000 cbm TFDE WilPride today has been committed on an 2-3 month time charter contract with expected gross revenues of between USD 10.3 million and USD 14.3 million. With forecasted all-in cash break-even of about USD 58,000 per day per vessel in 2021 the contract is estimated to generate surplus liquidity of between USD 6.2 million and USD 8.6 million.   The contract is expected to commence upon redelivery from the current contract in the first half of February 2021.   Gas prices and spot LNG shipping rates have recently increased dramatically for several reasons including cold weather, various production disruptions and fleet inefficiencies. Forward gas prices for the remainder of 2021 has recovered together with consensus shipping rates. The Company’s financial results in 2021 are expected to improve on 2020.   Join our mailing list here We are #1 on Google and Bing for the "Largest Mobile Energy Network" Come join our community!

  Based on the previously announced Conditional Letter of Award, Maersk Drilling has been awarded contracts for the deepwater rigs Maersk Valiant and Mærsk Developer from Total E&P Suriname, Suriname Branch, for Total’s exploration and appraisal project in Suriname’s Block 58. Mærsk Developer and Maersk Valiant will be employed for an estimated combined total duration of 500 days. Mærsk Developer is expected to commence operations in January 2021, while Maersk Valiant is expected to commence operations in March 2021. The total value of the firm contracts is approximately USD 100m, including rig modifications, integrated services provided, and a mobilization fee for Maersk Valiant. The contracts include various extension options. “We’re thrilled to firm up these contracts, adding further to our long-standing relationship with Total for whom we have a great track record from our collaboration on a number of deepwater exploration projects. We’re happy to add to our presence in the exciting Suriname-Guyana basin and will be able to leverage the fact that Mærsk Developer is already operating offshore Suriname to quickly start up operations including provision of a range of integrated services to maximise efficiency,” says COO Morten Kelstrup of Maersk Drilling. Mærsk Developer is a DSS-21 column-stabilized dynamically positioned semi-submersible rig, able to operate in water depths up to 10,000 ft. It was delivered in 2009 and is currently mobilizing for the Total campaign after recently completing a contract offshore Suriname. Maersk Valiant is a high-specification 7th generation drillship with integrated Managed Pressure Drilling capability which was delivered in 2013. It is currently warm-stacked in Aruba after finishing a campaign offshore Mexico in June 2020.   Join our mailing list here We are #1 on Google and Bing for the "Largest Mobile Energy Network" Come join our community!

  Canada’s Minister of Environment and Climate Change, Jonathan Wilkinson, announced on Monday that the proposed BHP’s Canada Exploration Drilling Project, Equinor’s Central Ridge Exploration Drilling Project and Chevron’s West Flemish Pass Exploration Drilling Project can proceed.   The projects will allow the proponents to determine the presence, nature, and quantities of the potential hydrocarbon resources within their explorations licenses located approximately 350 to 375 kilometers offshore east of St. John’s, Newfoundland and Labrador, the government explained.   The proponents, BHP, Equinor, and Chevron can now proceed with obtaining any additional authorizations and permits from federal departments, as well as the Canada-Newfoundland and Labrador Offshore Petroleum Board.   Read more on each project here:   BHP - BHP Canada Exploration Drilling Project    Equinor- Central Ridge Exploration Drilling Project    Chevron- West Flemish Pass Exploration Drilling Project    Join our mailing list here We are #1 on Google and Bing for the "Largest Mobile Energy Network" Come join our community!
