Barents Sea well to appraise Norvarg gas potential
The semisubmersible Leiv Eiriksson has spudded the Norvarg 2 appraisal well in license PL 535 in the Norwegian sector of the Barents Sea.
OSLO, Norway – The semisubmersible Leiv Eiriksson has spudded the Norvarg 2 appraisal well in license PL 535 in the Norwegian sector of the Barents Sea.
Total discovered gas with its first well on theNorvarg structure in 2011, which was one of the 10 largest offshore discoveries worldwide that year, says partner Rocksource.
The main objective of the current well is to prove up the volume potential in the northeast segment of the Norvarg closure. Drilling is estimated to take between 69 and 104 days.
The program is designed to test the reservoir quality of the channel sands in the main Kobbe formation. These sands could have much higher productivity than those in the discovery well, Rocksource says.
A successful outcome would add to the commerciality of the find, which is in an area remote from infrastructure. Rocksource estimates potential resources at 290 MMboe. Total’s estimate is 200 MMboe-plus.
Toward end-2013, Rocksource expects to participate in another well in the Barents Sea on the Langlitinden prospect in PL 659, to be drilled by the semisubTransocean Barents and operated by Det norske oljeselskap.
This well will target additional prospectivity to that found on the same structure as Statoil’s 2008, 190-MMboe Caurus gas find.
