AMSTERDAM, the Netherlands – Shell has reportedly agreed to sell a 25% interest in the producing Sean field and adjacent exploration areas in the UK southern North Sea to Dutch independent Oranje-Nassau Energie (ONE).

The deal remains subject to partner and regulatory approvals but is expected to be completed during the first half of 2015.

Last week ONE revealed it had successfully appraised the M07-B gas field across the median line in Dutch waters via an extended-reach well drilled from the M07-A platform. On test it flowed gas from a Jurassic accumulation at a maximum rate of 1 MMcm/d (40 MMcf/d) and 250 b/d of associated condensate.

M07-08 was the third well on the field that was discovered in 1996. The well encountered the reservoir at a level 8 m (26 ft) shallower than expected and the gas down to 10 m (33 ft) deeper than expected.

Results suggest there could be the basis for further development of the M07-B field from a new satellite location in the future, ONE said.

Earlier this year ONE proved a new Triassic light oil and gas accumulation via the P11-11 well in license P11a, 55 km (34 mi) northwest of the Rotterdam Harbor entrance in theDutch North Sea.

The reservoir target was relatively shallow at a depth of around 2,300 m (7,544 ft). The well flowed up to 900,000 cu m/d (30 MMcf/d) gas and 100 cu m/d condensate on a 52/64-in. choke, with only 4 bar (58 psi) drawdown. ONE may consider producing the structure with a new unmanned facility, connected to existing infrastructure in the area.
