Sapura Completes Prelude Well Intervention Work
Wednesday 28 June 2017
Malaysia’s Sapura Energy has wrapped up a light well intervention campaign at Shell’s Prelude floating liquefied natural gas development off the coast of Western Australia.
The work involved the retrieval of eight suspension plugs from seven wells at the Prelude field and was carried out under the five-year call-off service agreement awarded to Sapura in June last year.
It was previously reported the wells included the Crux 2ST1, Crux 3, Crux 4 and Auriga West-1 located in Block AC/RL9; Crescendo-1 in Block WA-371-P; Prelude-1a in Block WA-44-L and Trio-1 outside of an existing Shell permit area in Block 1338.
Sapura used its Sapura Constructor intervention vessel, utilising its riserless light well Intervention system which the company says allows work to be carried out on subsea wells without the use of a conventional drill rig.
Shell’s Prelude project lies in the Browse basin, roughly 200 kilometres off the West Australian coast, and will have the capacity for 5.3 million tonnes per annum of LNG.
