Sururu recorded such a record in a well completed on July 13 and is well above the average of the others that also recorded a large oil column (436 meters).
In a press conference, talking about Petrobras' 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... of our very selective and priority allocation, careful… betting on results like this”.

As predicted, productivity in the pre-salt layer is being positive and are increasingly confirming according to estimates and in some situations even exceeding expectations, says Solange. the executive said that “We are facing a unique type of reservoir, without many similar ones in the industry, we are very cautious when making productivity forecasts and today we found out, yes, after practically eight years producing in the pre-salt layer, that our vision more likely it is taking place with an optimistic bias”, as the state-owned operator already exceeded 1,5 million barrels in April. The advance in productivity has benefited from the lesson learned over the past 8 years.
