Petrobras Initiative Aims to Innovate Oil Exploration in Deep Waters with High CO2 Gas

Petrobras is developing a new project aimed at the separation and reinjection, still on the seabed, of the high CO2 gas generated along with the oil. The oil company operating in the Libra consortium announced that it has started hiring suppliers for the project’s execution, construction, installation, and performance testing of HISEP®, a technology patented by it. The forecast is that the manufacturer will be selected by August 2022 and that the equipment will be installed in 2025.

According to Petrobras, HISEP® can inaugurate a new way of exploring and developing oil production in deep and ultra-deep waters, and in locations where there are reservoir fluids with high gas-oil ratios and CO2 content.

“HISEP® will enhance oil production by freeing up space in the surface gas processing plant. The pilot test is scheduled to take place in the Mero 3 area, which is expected to start production in 2024,” said Petrobras.

Once the technology is proven, during a two-year testing period, the project could be applied in other areas, such as Libra Central and Jupiter, where it has the potential to make production development feasible.

“Once HISEP® technology is proven, it will also be possible to develop offshore production units with smaller and less complex gas processing plants, which have lower costs and construction timelines, as well as lower operational costs,” it explained.

Consultation Since 2017

Since 2017, Petrobras has been consulting companies to identify the equipment they have already developed that could be adapted for the project, as well as the main technological bottlenecks that exist so that the project can become a reality.

In this way, Petrobras is working together with companies in the market under the concept of early engagement, that is, with the participation of suppliers to develop the technology from the early stages of the process, to define and develop the solution to be used in the final product. The goal is to make the technology technically feasible and also replicable, as well as commercially attractive for the market.
