With a 910-Day Contract and the Possibility of Extension to 3.5 Years, the Drillship DS Carolina Promises to Increase Production in the Sepia and Atapu Oil Fields in the Santos Basin, with Drilling in Water Depths of Up to 40,000 Feet.
Petrobras, the Brazilian state-owned energy giant, has just taken another strategic step in the exploration of oil in ultra-deep waters. The company has signed a long-term contract with Ventura Offshore Midco for the use of the drillship DS Carolina, which will be deployed in the Sepia and Atapu oil fields in the Santos Basin. But what does this mean for the future of the offshore sector in Brazil?
The Sepia and Atapu oil fields are true treasures along the coast of Brazil. They not only reinforce the potential of the pre-salt but also attract investments from international giants. With the support of the DS Carolina, Petrobras hopes to further increase its efficiency and safety in operations.
What is a Drillship and Its Importance for Oil Fields

Do you know what a drillship is? These sea giants are true “floating laboratories,” designed to drill and explore the seabed in search of oil and natural gas. Equipped with cutting-edge technology, they operate in deep and ultra-deep waters, where fixed platforms cannot reach.

In the case of Brazil, drillships are essential to unlock the potential of the pre-salt. With gigantic reserves located thousands of meters below sea level, only vessels like the DS Carolina can perform safe and efficient operations in these challenging fields.
Contract Details Between Petrobras and Ventura Offshore
The contract signed between Petrobras and Ventura Offshore Midco is robust. Valued at approximately $363 million, it provides for an initial term of 910 days for operations, with a possible extension of 305 days. This means that the DS Carolina could operate in these fields for up to 3.5 years if the option is exercised.
Guilherme Coelho, CEO of Ventura Offshore, highlighted the company’s commitment to delivering safe and efficient operations. This partnership reflects the long history between the two companies, which have worked together to promote oil exploration in Brazil.
Characteristics of the DS Carolina
The DS Carolina is not just any drillship. It belongs to the sixth generation of drilling rigs, which means it is equipped with the most modern offshore technology. With the capacity to drill up to 40,000 feet in depth, it can operate in waters up to 10,000 feet deep.
Additionally, the DS Carolina features advanced dynamic positioning (DP) systems, ensuring greater stability and safety during operations. It’s like having a “surgeon” at sea, precise and efficient in every drilling operation.
Sepia and Atapu Oil Fields: Why Are They Strategic?
Located in the rich Santos Basin, the Sepia and Atapu oil fields are fundamental for Petrobras and its international partners. These areas are known for their abundant reserves and the quality of the extracted oil, making them one of the pillars of Brazil’s pre-salt.
In the Atapu field, Petrobras works alongside companies like Shell and TotalEnergies, while the Sepia field has partners such as Petronas and QatarEnergy. This diversity of players reinforces the global importance of these projects, which put Brazil on the radar of the largest oil companies in the world.
The contracting of the drillship DS Carolina is yet another chapter in the expansion of the Brazilian offshore industry. With ambitious projects like Sepia and Atapu, Petrobras consolidates its position as a leader in oil exploration in ultra-deep waters.
