Oilfield services giants, Halliburton and Petrofac have become the new members of the drilling exploration pact previously between Seapulse and Maersk Drilling. Under the pact, the quartet will carry out work on a “global wells programme”. The alliance will see Petrofac providing well management services, and Halliburton will deliver integrated well services. Maersk Drilling will offer drilling services and subcontracts.
