RIO DE JANEIRO -- Production of first oil in the pre-salt layer, in the Jubarte field, in the Campos basin is under way, according to Petrobras.
The first well's production potential is 18,000 b/d, the company says. Petrobras is developing the well in order to obtain knowledge that will help the company develop the pre-salt reserves located in Espírito Santo and in other places off the Brazilian coast.
The characteristics of the light pre-salt oil (30° API) required investments of nearly $50 million to adapt the platform's process plant, complete well 1-ESS-103A, and interconnect the well to the FPSO JK.
Production will begin with a long duration test (LDT) to observe how pre-salt oil behaves, both in the reservoir and in the platform's process plant. The LDT is expected to last six months to a year, the company says.
