OSLO, Norway – The semisubmersible Deepsea Stavanger has completed two appraisal wells on the Gekko gas/oil discovery in the Norwegian North Sea for Aker BP.
Both were drilled in 120 m (393.6 ft) of water in license PL 203, 5 km (3 mi) east of the Volund field and 200 km (124 mi) northwest of Stavanger.
Gekko was discovered in Palaeocene reservoir rocks (Heimdal formation) in 1974. Aker BP aimed to prove a potentially thicker oil column in the formation, and to address uncertainties over the reservoir.
Well 25/4-13 S south on the structure encountered a 43-m (141-ft) oil and gas column in the Heimdal formation, of which 6.5-m (21-ft) was oil.
Well 25/4-13 A north on the structure penetrated a 30-m (98.4-ft) oil and gas column in the same formation, of which 6 m (19.7 ft) was oil.
According to the Norwegian Petroleum Directorate (NPD), initial analysis suggests 0.9-2.3 MMcm of recoverable oil and 3.8-6.3 bcm of recoverable gas, which could be tied back to the Alvheim FPSO.
The wells were not formation-tested, but extensive data acquisition and sampling have been carried out.
TheDeepsea Stavanger will now leave the Norwegian shelf to start an assignment for Total.
The NPD has authorized Wintershall to drill exploration well 6706/6-2 S in PL 847 in the Norwegian Sea, using the semisubTransocean Spitsbergen.
This will target a prospect 7 km (4.3 mi) northwest of the 6706/6-1 (Hvitveis) discovery.
