Petrobras revealed on Tuesday that it has initiated trials for an innovative technology designed to separate oil from CO2-rich gas directly on the seabed. This technology, known as Hisep, is a creation of the Petrobras Research Center (Cenpes) and represents a significant advancement in the field. The development is supported by a substantial investment of $1.7 billion from the consortium responsible for the Libra block in the pre-salt Santos Basin. This consortium includes Petrobras itself, along with industry giants Shell, Total, and the state-owned Pre-Sal Petróleo (PPSA), as well as Chinese entities CNPC and CNOOC.
Out of the total investment, $1.5 billion fuels the launch of the Hisep pilot project. The remaining $200 million is earmarked for the establishment of the Brazilian Pre-Salt Technology Center (CTPB), a collaborative effort with the Federal University of Itajubá (Unifei), located in the state of Minas Gerais.
The Hisep technology is set to undergo pilot testing in the Mero 3 field within the pre-salt Santos Basin. Following this testing phase, Petrobras anticipates that the technology will be operational by 2028. Positioned within the Libra area, the Mero field is recognized as the third-largest in the pre-salt region.
Petrobras’s Engineering Director, Carlos Travassos, highlighted the significant advantages Hisep technology is set to bring to the company’s operations. With its implementation, Petrobras expects not only to streamline efficiency but also to unlock substantial value. The innovative technology is projected to slash the weight of platforms by an impressive 65%, leading to a consequential reduction in the number of personnel required onboard. Furthermore, the potential for commercializing this technology to other entities in the oil sector presents an additional revenue stream.
“By integrating Hisep, we anticipate a transformation in the layout of the Floating Production, Storage, and Offloading (FPSO) units, particularly the ‘topside’ or upper part of the FPSO, which can reduce the cost of the platforms. This technology allows for a significant portion of the processing plant to be relocated from the FPSO to the seabed,” says Mr. Travassos. The FPSO platform produces, processes, stores, and drains oil.
In a strategic move to advance the Hisep project, Petrobras entered into an agreement with FMC Technologies do Brasil, a TechnipFMC subsidiary, in January. This partnership is tasked with developing the necessary infrastructure for Hisep. The initiative will kick off with the FPSO Marechal Duque de Caxias, which is designed to process up to 180,000 barrels of oil and 12 million cubic meters of gas daily.
Jean-Paul Prates, CEO of Petrobras, emphasized the environmental and operational benefits of their latest technological advancement, Hisep. He said that the primary advantage of this innovation lies in its capacity to mitigate the environmental impact of polluting gases at the source. “Decarbonization is crucial for the sustainability of oil extraction activities, enabling us to continue utilizing hydrocarbons,” Mr. Prates said. After separation, Hisep allows for the immediate reinjection of these gases back into the subsea wells.
“In the near future, Hisep will significantly reduce the need for personnel in high-risk areas of the platform, mirroring our successful efforts to eliminate diving operations by reallocating staff to safer roles. This strategic move bolsters our production efficiency,” he said.
