Santos Basin Reports Its Largest Oil Column Ever Found In The Pre-Salt

Largest Oil Column in Pre-Salt Santos Basin Found in Sururu Field with Record Size.

The Santos Basin registers in one well the largest oil column ever found in the pre-salt (reaching a size of 530 meters). The Sururu field, operated by the state-owned Petrobras, where this confirmation was recorded by Solange Guedes, director of Exploration and Production of the oil company. Sururu set this record in a well completed on July 13 and is well above the average of others that also recorded large oil columns (436 meters).

In a press conference discussing Petrobras’s results at the end of the first half of 2018, Solange said: “Our best results were below 500 meters: this gives us confidence in the investment trajectory… in our very selective and priority allocation, careful… betting on results like this.” The column identified is a vertical section.

Sururu Field Participants

• Petrobras – 42.5 %;
• Shell – 25 %;
• Total – 22.5 %;
• Galp – 10 %;

As anticipated, productivity in the pre-salt is proving to be positive and is increasingly confirming estimates, and in some cases even exceeding expectations, says Solange. The executive stated that “We are facing a unique type of reservoir, with few similars in the industry, we are being very cautious in making productivity forecasts and today we can confirm, after nearly eight years producing in the pre-salt, that our most likely vision is coming true with an optimistic bias,” as the state operator has already exceeded 1.5 million barrels in April. The advancement of productivity has been benefited by the lessons learned over the past 8 years.
