The Valaris DS-17 drillship has been tasked to drill an appraisal well, plug an old exploration well and conduct additional drilling scope in Brazil.

“Brazil is one of Equinor’s core areas, and Bacalhau is one of our flagship projects internationally. We are pleased to land an agreement with the Valaris, on deliveries from an advanced drillship for this important field. We look forward to working with one of the world’s largest rig contractors and we have high expectations to their deliveries on safety and efficiency,” says Geir Tungesvik, executive vice president for Projects, Drilling and Procurement.

Drilling services and other additional services such as remotely operated vehicle (ROV), managed pressure drilling (MPD), casing running, slop treatment and cuttings handling are included in the contract. A fuel reduction incentive has also been agreed on.

“The second rig in Bacalhau will expand our drilling capacity in Brazil and will further enhance our understanding of Bacalhau North through an ADR (Reservoir Data Acquisition) well. The decision to bring in DS-17 demonstrates our commitment to create value in Brazil, where we have a long-term presence perspective,” says Veronica Rezende Coelho, country manager in Brazil.

DS-17 is an ultra-deepwater drillship, capable of operating in water depths of more than 3600 metres.

Partners in Bacalhau: Equinor 40% (operator), ExxonMobil 40%, Petrogal Brasil 20% and Pré-sal Petróleo SA (production sharing agreement manager, not an investor).
