OSLO, Norway – ENGIE E&P Norge has discovered more oil and gas close to the Gjøa field infrastructure in the Norwegian North Sea.
The semisubmersible Transocean Arctic drilled well 36/7-4 on the Cara prospect, encountering a 60-m (197-ft) oil column and a 50-m (164-ft) gas column in the Agat formation.
ENGIE E&P estimates recoverable volumes in the range of 4-11 MMcm, or 25-70 MMboe.
The well, 6 km (3.7 mi) northeast of Gjøa field, reached total depth in the Åsgard formation of Lower Cretaceous.
Cedric Osterrieth, ENGIE E&P Norge’s managing director, said: “We will now evaluate the possibility to link the discovery to existing infrastructure at the nearby Gjøa field. This will reduce both time and costs concerning a future development.”
Gjøa produces through a semisubmersible floating production platform.
Extensive data acquisition, including wireline logging and three successful core runs, has revealed good reservoir quality, with strong flow rates from the production test.
Head of subsurface Raphaël Fillon said: “The well provides important new information on Cretaceous reservoir distribution and quality in this area. The Cara discovery gives us also an increased understanding of the subsurface, and strengthens our view on other licenses in this area.”
This was the first exploration well on production license 636, awarded under Norway’s 2011 Awards in Predefined Areas round.
The Transocean Arctic will P&A the well.
