When the results of the Glengorm discovery well (22/21c-13) came in early 2019, partner Total announced that the accumulation could hold 250 MMboe recoverable.
Following the completion of two appraisal wells, this number has now been significantly reduced.
The first appraisal well, 22/26d-3, was completed in April last year. It tested a separate closure to the southeast of Glengorm that was named Cringletie by Maersk. Unfortunately, this well came in dry.
Just before the Christmas break last year last year, CNOOC announced that the second appraisal well (22/21c-14). It did test the closure of the initial discovery well, but yielded “no commercial hydrocarbons” either.
As a consequence, Westwood Global has now downgraded the volumes potentially to be recovered from Glengorm to be maximum 60 MMboe, as published in a news item last week, .
Although much lower, this volume may still be commercial as a tie-back, for instance to TotalEnergies’ Elgin-Franklin facilities. At a distance of around 50 km, it is not a short-distance tie-back though. It therefore remains to be seen what CNOOC will decide.
