Petrobras receives OTC award for innovative well technology

In order to develop this new solution, Petrobras used a combination of BOP, (Blowout Preventer – safety equipment that controls well pressure) anchoring technology, and real-time riser (column connecting the rig to the well) analysis. The main advantage if this combination is the possibility of using more modern dynamic positioning rigs to replace anchored rigs.

This new method reduces the duration of interventions in shallow water wells by seven days, resulting in reduced costs and an average reduction of 10% in terms of greenhouse gas emissions. Additionally, it reduces the impact of anchoring on the seabed by 99%, when compared to the use of traditional rigs, reducing the impacted area on the seabed in the same proportion. Thanks to this, this new technology makes operations in congested or environmentally sensitive areas much more feasible.

“Receiving another award from OTC, the main entity of the global offshore industry, in the year when Petrobras celebrates its 70th anniversary, makes us very proud. We’re being recognised for our technical capabilities and the competence of our workers, who are constantly seeking the best solutions and the best results, always guided by the most rigorous safety standards. Throughout our history, we knew how to turn challenges into innovative technologies, which have shaped our evolution and have left a one-of-a-kind legacy for the segment. We must recognise that, it if weren't for the dedication and excellence of our professionals, alongside our partners and suppliers, we wouldn’t have made it this far”, said Petrobras President, Jean Paul Prates.

First shallow water BOP anchorage in the world

This new solution made it possible for rigs operating in deep water locations to also operate in shallow water locations, being adjusted with the BOP anchored for this purpose. Thanks to this method, Petrobras carried out the first shallow water BOP anchorage in the world, without using anchoring vessels, reducing costs and allowing the operation of wells that are difficult to reach. Another advantage of this technology is the significant increase in the safety of operations.

Petrobras envisages to make use of this new solution in future projects aimed to revitalise mature oilfields, meeting environmental requirements by operating wells with the lowest possible impact.
