UK energy major BP has spudded a much-anticipated appraisal well on the Puma West oil discovery in the deep-water Gulf of Mexico.

Joint venture partner Talos Energy said the appraisal well was spudded last month and the company anticipated drilling results in early 2023.

The appraisal follows on from the successful 2021 exploration discovery well, which is on Green Canyon Block 821 and about 24 kilometres west of BP’s producing Mad Dog oilfield.
