Offshore drilling contractor Shelf Drilling has secured contract extensions for the Shelf Drilling Chaophraya and Shelf Drilling Krathong jack-up rigs with Chevron Thailand Exploration and Production for operations in the Gulf of Thailand, Shelf Drilling reported on Dec. 27.

David Mullen, CEO of Shelf Drilling, commented, “We are very pleased to announce the contract extensions for the Shelf Drilling Chaophraya and Shelf Drilling Krathong with Chevron in the Gulf of Thailand. The high specification jack-up rigs were uniquely built fit for purpose for Gulf of Thailand drilling activity. The extension of both rigs further demonstrates our valued relationship with Chevron and our commitment to the Kingdom of Thailand.”

Shelf Drilling noted in a press release that the extensions of the two sister rigs—the Krathong and the Chaopraya—are in direct continuation of the planned out of service projects at the end of each rig’s current contract with the same client.

The duration of the contract extension for the Shelf Drilling Chaophraya rig is 39 months, while the Shelf Drilling Krathong rig’s extension is for 36 months and the start of these contracts is expected in the third quarter of 2022 and the fourth quarter of 2022, respectively.

According to Shelf Drilling’s fleet status report from November 2021, the Shelf Drilling Chaophraya rig has been under a contract with Chevron in Thailand since December 2016, while the Shelf Drilling Krathong jack-up rig has been under a contract with the same client since June 2017.
