Transocean, Jurong Shipyard agree to delay delivery, defer payments of two drillships

In early June, Transocean announced an agreement with Jurong Shipyard (JSPL) to delay delivery of the ultra-deepwater drillships Deepwater Atlas and Deepwater Titan. As part of the agreement, JSPL will accept deferred payment for both rigs.

The Deepwater Atlas and Deepwater Titan are the world’s first eighth-generation ultra-deepwater drillships and the only rigs to feature a 3 million-lb hookload. They will also include the first 20,000-psi well control systems.

Delivery of the Deepwater Atlas is now expected in December 2021. Upon delivery, Transocean will make a $50 million payment to JSPL; the balance of payments, or approximately $370 million, will be payable during a five-year period following delivery. Transocean expects Beacon Offshore Energy to commence drilling on its Shenandoah project in the US Gulf of Mexico, utilizing the Deepwater Atlas, in Q3 2022, following the final investment decision. That decision is expected by 31 July.

Delivery of the Deepwater Titan is now expected in May 2022. Upon delivery, Transocean will pay JSPL 80% of amount owed, or approximately $350 million. The remaining $90 million, will be deferred and payable over a five-year period following delivery. Transocean has agreed with Chevron to start commercial operations of the Deepwater Titan in Q1 2023. Transocean’s contract with Chevron maintains its duration and estimated backlog of $830 million, excluding mobilization and reimbursables.

BP Announces startup of Manuel in US Gulf of Mexico

The BP-operated Manuel project has successfully started up in the US Gulf of Mexico. It is the fourth of five major projects expected to be delivered globally by the company in 2021. Manuel includes a new subsea production system for two new wells tied into the Na Kika platform. 

The wells are expected to boost gross platform production by an estimated 20,100 BOE/day. Drilled to a depth of approximately 21,000 ft, the wells are located southeast of the Na Kika platform, approximately 140 miles off the coast of New Orleans. BP and Shell each hold a 50% working interest in the Manuel development.

In separate news, the operator also announced the start of gas production from the Raven field, the third stage of its major West Nile Delta (WND) development off the Mediterranean coast in Egypt. 

The approximately $9 billion WND development includes five gas fields across the North Alexandria and West Mediterranean deepwater offshore concession blocks in the Mediterranean Sea. Raven follows the Taurus/Libra and Giza/Fayoum projects, which started production in 2017 and 2019, respectively. It produces gas to a new onshore processing facility, alongside the existing WND onshore processing plant.

Raven is currently producing approximately 600 million standard cu ft/day of gas. At its peak, the field has the potential to produce 900 million cu ft/day and 30,000 bbl/day of condensate.

In total, the WND development encompasses 25 wells producing gas to the onshore processing plants. BP is the operator and has an 82.75% stake in the development, with Wintershall Dea holding the remaining 17.25% interest.

Talos Energy successfully drills Tornado Attic well

Talos Energy announced that it has successfully discovered pay in line with pre-drill expectations on its Tornado Attic sidetrack well in the US Gulf of Mexico.
