The Brazilian Oil and Gas Company PetroRio Initiated Production at the Fifth Well in the Tubarão Martelo Field, Offshore
PetroRio stated this Tuesday that the commencement of production at the well was part of a revitalization campaign for the field. The revitalization campaign consists of a workover at the TBMT-2HP well with the replacement of the submersible pump and the connection of a fifth producing well – TBMT-4HP – to the FPSO OSX-3 owned by PetroRio.

In June 2020, Dommo Energia – then operator of Tubarão Martelo – announced positive results from the workover, which increased production levels in the field to around 7,000 barrels of oil per day.
As soon as the workover was completed, the connection of TBMT-4HP was made, resulting in initial production of approximately 3,000 barrels per day, thus bringing total field production to 10,000 barrels per day, or an increase of 40 percent compared to previous levels.

Tubarão Martelo Tie-in to Polvo Field
The company estimates that the project investment will reach around US $ 45 million to be disbursed during the first half of 2021.
Furthermore, PetroRio expects to leverage the connection of the Polvo field to FPSO OSX-3 to make new investments for the connection of a sixth well – the TBMT-10H well – which may cost between US $ 20 million and US $ 25 million.
