LONDON – Shell will operate the Arran field development in the UK central North Sea after the partners took a final investment decision.

Concurrently,RockRose Energy has completed acquisition of a 20.43% interest in blocks 23/11a, 23/16b and 23/16c, containing Arran, thereby lifting its interest in the field to 30.43%.

Four new development wells will be drilled, and the produced natural gas and liquids will be exported through a newly installed subsea pipeline to Shell’s Shearwater platform.

At peak, Arran should produce around 100 MMcf/d of gas and 4,000 b/d of condensate.

Elsewhere in this area, RockRose management last week visited theFPSOBleo Holm which produces oil from the Ross and Blake fields.

An integrity study is under way to appraise the infrastructure needed to sustain recovery of discovered hydrocarbons in the area.

In the southern North Sea, on the UK/Dutch median line, RockRose is participating in the Spirit Energy-operated ST1/Markham platform decommissioning program. TheStanislav Yudin was due to remove the topsides and jacket in separate lifts.

A heavy-lift vessel will also remove the topsides of the Petrogas-operated Q1 Halfweg platform in the next few months to conclude abandonment of this field.

Finally, Petrogas has spudded an infill well on the A18 field in the Dutch North Sea A/B block. According to RockRose, this should take around 40 days to drill and complete.

The field produces from stacked Pleistocene marine sands, currently from the older Q6A, Q7 and Q8 sands. However, the latest well is targeting the shallower Q3.2 and Q4 sand units.
