RWE Dea Norge AS says it will temporarily plug and abandon an appraisal well of the 2010 Titan discovery in the Norwegian North Sea (OGJ Online, Mar. 3, 2014).

The company conducted five mini-drillstem tests and said oil was proved in the Brent Group and the Heather, Drake, Cook, and Statfjord formations in production license 420.

Appraisal well 35/9-11 S and sidetrack 35/9-11 A are 16 km west of the Gjoa field. The Norwegian Petroleum Directorate (NPD) said the wells were drilled 1.7 km southwest of the 35/9-6 S oil, gas, and condensate discovery well (OGJ Online, Dec. 8, 2010).

The 35/9-11 S well was drilled to a vertical depth of 3,733 m below the sea surface by the Ocean Rig ASA’s Leiv Eiriksson semisubmersible drilling rig in 368 m of water. NPD said the 35/9-11 A well was drilled 30 m from 35/9-11 S “for optimal core samples” and reached 3,795 m.

RWE Dea said the purpose of the drilling was to delineate the Titan discovery toward the south and to reduce uncertainty in reservoir thicknesses and properties.

“The well results increase our understanding of the area, which will be useful in the further exploration of the greater Titan area,” said Hugo Sandal, managing director.

RWE Dea Norge is operator of PL 420 with 30% interest. Other partners are Statoil Petroleum AS 40% and Idemitsu Petroleum Norge 30%.
