Stella well to assess development potential

CALGARY, Alberta -- Transocean’s heavy-duty jackup Galaxy II has mobilized to the UK North Sea to drill an appraisal well on the Stella field. Drilling should start later this month.

In November, Ithaca Energy became operator of the field and two further discoveries in block 30/6 -- Hurricane and Harrier. ADTI will manage operations for the well under a turnkey contract.

The program should take 79 days to complete, with three main objectives. These are to confirm the assessment of in-place hydrocarbon volumes, to determine the changes in the composition of hydrocarbon fluids with depth, and to verify the quality and distribution of the reservoir. Work will include drillstem testing with a contingent side track.

Ithaca says the well should reach its total planned depth in the Cretaceous chalk beneath the main Stella (Andrew) reservoir target. A previous well (30/6-3Z) encountered hydrocarbons in the Ekofisk chalk reservoir, also testing rich gas-condensate reserves that could be developed in tandem with the main pool.

Depending on the results, Ithaca and its partners Challenger Minerals and Dyas may develop Stella with Harrier and Hurricane as tiebacks.
