Maureen Sands.22 Dec 2019 18:05
I was wondering about the Maureen Sands formation. They mentioned at the CMD, but history shows it’s a bit hit and miss. So does it add any value? Given they have contracted a drilling rig next year for Kraken.. why not just drill a bit deeper if it lies underneath and see what’s there
Statoil have Mariner that gets it’s oil from the Maureen Sands, but Nautical Petroleum already tried to look at the Maureen Sands in Block 9/11c in 2007 but were disappointed. Apparently “water wet”.
As ours lie underneath Kraken Block 9/2b and 9/2c, I’d say there is no guarantee the Maureen formation is any good. It may be better not to invest and chase production this way. Stick to the easy stuff in Malaysia and Magnus/Kraken. I don’t think Nautical Petroleum knew about the Maureen formation underneath Kraken. Whether Enquest with better seismic today can tell whether a formation is water wet without drilling must be a question to ask someone at HQ. Indeed why not just drill it next year if the rig is already there. 90 day contract seems reasonable for 2 wells, but TL always did them much quicker. Stena should just drill an extra one/bit while they are there.
History from 2007
Nautical Petroleum says that the Mermaid exploration well 9/11c-13 spudded on November 22, 2007. 9/11c-13 is an exploration well on the Mermaid Prospect, which is analogous to and lies directly south of the Mariner discovery (Block 9/11a). This is Nautical's second operated well and initial results are expected towards the end of December.
The interests held in Block 9/11c are Nautical Petroleum 50%, Celtic Oil Limited (wholly owned by SK Energy) 40% and Silverstone CNS Limited 10%.
Commenting on the spudding, Steve Jenkins Chief Executive of Nautical said:
"Mermaid is the second prospect Nautical is testing in our drilling program, where the technical work completed to date suggests that best estimate prospective resources total 129 mmbo. If successful, this will represent a further material addition to Nautical's resources and reserves."
Results:
Nautical Petroleum reports the results of the 9/11c-13 Mermaid exploration well, the second well in the campaign after the highly successful Kraken appraisal well.
Well 9/11c-13 was drilled to 5113 feet and encountered excellent quality sands at Tertiary Heimdal and Maureen level. All depths were very close to prognosis, however, both the main Maureen target and the secondary Heimdal objectives were water wet.
Nautical will assess the data gathered from the well and integrate with the 3-D seismic to ascertain the future potential of the block. The interests held in 9/11c are Nautical Petroleum 50%, Celtic Oil Limited (wholly owned by SK Energy) 40% and Silverstone Energy Ltd 10%.
Commenting on the well result, Steve Jenkins, Chief Executive of Nautical said:
"This is a disappointing result, especially following the Kraken (9/2b-2) appraisal which proved a larger oil accumulation than our maximum case.
