With the TOTUS technique, Petrobras managed to halve the cost of drilling a well in the Golfinho field, in the Espírito Santo Basin

This Tuesday (14), Petrobras informed the market of the promising result of using a new technique from the state-owned company, True One Trip Ultra Slender (TOTUS). With this new concept, the oil company cut the cost of drilling the 50 GLF 7H ESS subsea well by 49% in the Golfinho field, located in the Espírito Santo Basin.

TOTUS consists of simplifying and reducing the time spent in the drilling and completion phases of oil and gas wells. This technique helped to reduce the unit's construction time to 44 days, the historical average of which was previously 96 days per well.

According to Petrobras, the application of “Totus” presents a significant potential for cost reduction between US$ 20 million and US$ 35 million per well, in the period 2021 and 2025.

“The TOTUS concept, developed and patented by Petrobras, is part of the company's effort in the search for technological solutions that aim to reduce costs in its activities in a safe and efficient way. The concept consists of drilling the well in just 3 phases (Ultra Slender) and completion (upper and lower) installed in a single maneuver (True One Trip), different from traditional configurations (4 or 5 drilling phases and 2 or more maneuvers for install the completion),” the company said.

Petrobras also stated that the new concept could be used in some mature fields in the post-salt region, where the geological and reservoir characteristics are favorable to its application.
