Brazil’s Petrobras has issued two new tenders for the charter of low-specification drilling rigs to carry out a series of workover and well intervention activities, as the state-controlled oil company takes further steps to replenish its fleet.

Petrobras currently has a number of rig tenders in the market with plans to contract units for development drilling in the Buzios, Tupi and Roncador fields.

However, the two fresh opportunities will see Petrobras chartering rigs with a slightly simpler configuration to execute campaigns in the Campos, Santos and Espirito Santo basins, according to a source.

Drilling contractors including Transocean, Seadrill, Diamond Offshore, Noble Corporation, Valaris, Maersk Drilling, Constellation Oil Services, Ocyan and Petroserv are expected to have been invited to submit commercial bids on 8 June in both tenders.

In one of the tenders, Petrobras is looking to charter one or more rigs with high propulsive capacity to assist in the abandonment and decommissioning of old production platforms in Campos and Espirito Santo.

Petrobras is shopping for Class 2 or 3 dynamically positioned rigs, either semi-submersible units or drillships, to run operations in water depths ranging from 450 to 2400 metres.

Petrobras is offering three-year contracts and a mobilisation period of 180 days, with delivery scheduled for the second quarter of 2022.

The operator intends to conclude decommissioning of 18 production platforms and over 1000 kilometres of risers and flowlines by 2025, and the rig to be contracted will support such activities in the Marlim and Jubarte fields.

The second tender carries many of the characteristics of the first one, but will have Petrobras contracting a single rig, also with high propulsive capacity, with the addition of a blowout preventer when partially performing some duties.

Petrobras is shopping for a rig to conduct drilling, completion and intervention in the Campos, Santos and Espirito Santo basins.

As in the first tender, the contract on offer is for a period of three years, with the rig due to begin operations for Petrobras in the second quarter of 2022.

Both tenders feature a termination clause that allows Petrobras to cancel the charter on the 731st day of the rig contract.

Petrobras currently has a fleet of 20 drilling rigs, of which four have contracts expiring this year and another 11 with charters ending in 2022.

A 21st unit, the cylindrically shaped semisub Sevan Developer, is set to start its three-year contract with Petrobras in August.
