With the TOTUS Technique, Petrobras Managed to Halve the Drilling Cost of a Well in the Golfinho Field, in the Espírito Santo Basin
This Tuesday (14), Petrobras informed the market of the promising results from the use of a new technique by the state-owned company, the True One Trip Ultra Slender (TOTUS). With this new concept, the oil company minimized the drilling cost of the offshore well 7 GLF 49H ESS in the Golfinho field, located in the Espírito Santo Basin, by 50%.

According to Petrobras, the application of “TOTUS” presents significant cost reduction potential between US$ 20 million and US$ 35 million per well during the period from 2021 to 2025.
“The TOTUS concept, developed and patented by Petrobras, is part of the company’s efforts in search of technological solutions aimed at reducing costs in its activities safely and efficiently. The concept consists of drilling the well in just 3 phases (Ultra Slender) and the completion (upper and lower) installed in a single maneuver (True One Trip), unlike traditional configurations (4 or 5 drilling phases and 2 or more maneuvers to install the completion),” the company informed.
Petrobras also stated that the new concept may be used in some mature fields in the post-salt region, where the geological and reservoir characteristics are favorable for its application.
