Petrobras has halved well construction time in the Búzios field, with a 25% reduction in underwater costs.
The Company presented efficiency gains with the use of new technologies in the pre-salt Petrobras presented to the market its plans for the use of new technologies and digital transformation to increase efficiency in the production of oil and gas from pre-salt fields, especially Búzios and Libra. According to Petrobras’ Director of Production and Technology Development, Rudimar Lorenzatto, the application of technologies, standardization and economy of scale reduced the ramp-up time (reaching the maximum production capacity of one unit) of the pre-salt projects by 42% in the last seven years.
Rudimar represented Petrobras in a lecture held on Monday, 6/5, on the first day of the OTC. “Underwater costs were reduced by 25% in the Búzios and 39% in Lula fields. Gains in efficiency also accelerated the construction time of wells by 51% in the Búzios field since 2014, “commented the director. In addition to these results, he pointed out that Petrobras installed seven new oil and gas production systems in Brazil in eleven months, a remarkable result in the industry.
According to Rudimar, these seven units now produce more than 400,000 barrels of oil per day. Regarding the investment forecast, the director presented figures for the next five years. “The pre-salt will receive approximately $ 27 billion in investments from 2019 to 2023, while investment in post-salt development is expected to be about $ 21 billion. “Over the next five years, we plan to start operating eleven new production systems, seven of them being pre-salt, ” he said.
Libra Project has brought innovative technologies to the entire industry The development of the Libra area, in the Santos Basin pre-salt, stands out for the innovative and fast evolution solutions to overcome a challenging scenario in ultra-deep waters. The project was highlighted in the participation of Petrobras in the OTC, as the theme of a special session held this Monday, 6/5.
General Manager Paulo Rovina, who opened the session, pointed out that innovations employed in the Long-Term Test (TLD) project provided a deep knowledge of the Mero Field deposit, streamlining the project to develop four megaprojects in the area.
Wells with intelligent completion and 8-inch submarine pipelines enabled the production of the well in high flow (60,000 boed), reinjecting all the gas produced, including carbon dioxide, through the FPSO (petroleum production, storage and transfer unit) . It is an environmentally sound innovation that streamlines the knowledge of the behavior of the oil field and contributes to the reduction of CO2 emissions. Another outstanding solution is the tower where the production and injection lines – known as turret – are connected, which has the highest vertical tower load capacity in the industry.
