Petrobras initiative aims to innovate oil exploration in deep waters with gas with high CO2 content

Petrobras is developing a new project whose goal is to separate and reinject, still at the bottom of the sea, the gas with a high CO2 content that is generated along with the oil. The oil company that operates in the Libra consortium announced that it had started hiring suppliers to carry out the project, construction, installation and testing of HISEP®, a technology patented by it. The prediction is that the manufacturer will be chosen by August 2022 and that the equipment will be installed in the year 2025.

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

“HISEP® will provide increased oil production by freeing up space in the surface gas processing plant. The pilot test is expected to be carried out in the Mero 3 area, which should start production in 2024”, said Petrobras.

After the technology is proven, in a period of two years of tests, the project can be used in other areas, such as Libra Central and Jupiter, where it has the potential to make the production development project viable.

“Once the 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 construction costs and deadlines, as well as lower operating costs”, he explained.

Consultation since 2017

Since 2017, Petrobras has been consulting companies to identify the equipment that they had already developed and that could be adapted for the project, and also the main technological bottlenecks that exist so that the project could become real.

With this, Petrobras is working together with companies in the market in the modality understood by the concept of early engagement, that is, with the participation of suppliers to develop technology from the first 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 possible and also replicable, in addition to being commercially interesting for the market.
