The jack-up rig alliance between Aker BP, Maersk Drilling and Halliburton has delivered world-class performances. The drilling programme on Valhall Flank West is now complete. Over the course of 11 months, the Maersk Invincible rig set 12 conductors, drilled nine wells and drilled 22,000 metres of reservoir. Maersk Invincible arrived on the Valhall field in late June last year. After the 12 first large conductors were set, the rig drilled an average of one well per month. A total of nine wells have been drilled and completed. Three of these are multibranch wells. The drilling programme on Valhall Flank West is the first project delivered through the alliance and Maersk Invincible. Last winter, the rig set a new record on the Norwegian Shelf when it drilled 2278 metres in a 12¼” section in 24 hours. Maximum drilling speed achieved by the rig on the record-breaking day was 280 metres per hour. Four wells have started producing so far. The remainder are expected to start up through the year.

Valhall Flank West came on stream in December 2019, just two years after the Plan for Development and Operation was submitted to the Norwegian authorities. The giant Valhall field has produced more than one billion barrels of oil equivalent since the field was opened in 1982. The ambition is to produce another billion barrels over the next 40 years. Valhall Flank West is an important contribution.

Maersk Invincible will remain on the field through the summer to assist in ongoing well stimulation work. Aker BP has been the first company in the world to use a new method of well stimulation offshore. The single-trip multi-frac technology (link), which yields faster and thus less costly stimulation, is used on Valhall Flank West.
