Semi-sub Chevron Buckskin project at pre-FEED stage
The US super major Chevron and its partners, Maersk Oil (Maersk) from Denmark, Repsol from Spain and Samson Offshore Company (Samson) from USA, may consider to move a step ahead with the development of the oil and gas field Buckskin in the US part of the Gulf of Mexico meanwhile exploration should continue in the neighboring oil and gas field Moccasin.
Located in the Blocks 785, 872 and 736 of the Keathley Canyon approximately 350 kilometers south of Louisiana Gulf of Mexico coastline, the Buckskin and Moccasin oil fields were expected to be developed together.
In 2008 Repsol discovered Buckskin by 2,100 meters of water depth and 9,000 meters of total depth.
Few miles away, Chevron hit oil in 2011 at Moccasin by 2,000 meters of water depth and 9,600 meters total depth.
But in the meantime the exploration in Bockskin and Moccasin went in different ways.
In addition to the three years difference between both discoveries, the appraisal campaign went smoothly in Buckskin while Chevron and its partners were meeting some difficulties with Moccasin.
These different routes of development between Bucksin and Moccasin took importance on the second half 2013 as these field are owned by different joint ventures.
– Chevron 55% is the operator
– Maersk 20%
– Repsol 12.5%
– Samson 12.5%
In Moccasin, the different partners hold stakes such as:
– Chevron 43.75% is the operator
– BP 43.75%
– Samson 12.5%
In this context of multiple partners with different interests, the question came up if Buckskin and Moccasin should be developed jointly as originally planned.
WorleyParsons and Intecsea on Buckskin pre-FEED
In the case Moccasin could not be tied-in Buckskin semi-sub offshore platform, Chevron is prospecting around alternative source of supply from marginal field in stand-by as not large enough to justify stand alone floating production units.
In this scenario, Chevron and its partners Maersk, Repsol and Samson, may decide to engage the front end engineering and design (FEED) work on Buckskin semi-submersible platform in the coming months of 2014 regardless the situation in Moccasin.
