Petrobras will be able to carry out the 3D and 4D multiazimuth seismic survey activity in the fields of Albacora, Marlim and Voador, in the Campos Basin

Petrobras recently received the operating license from Ibama (Brazilian Institute for the Environment and Natural Resources) to carry out seismic research in the Campos Basin. The operation consists of 3D and 4D multiazimuth seismic monitoring in the Albacora, Marlim and Voador fields, all located in the Campos Basin. The document issued by the national body will be valid for 4 months. Check out this news: Petrobras invests in technology for remote monitoring of platforms in the Campos Basin

The research that Petrobras will carry out on the assets in the Campos Basin

The new Petrobras survey, for which Ibama granted the license, may be carried out using the seismic vessel SW Empress, owned by the company Shearwater GeoServices. In May, the seismic data acquisition company announced that it had won this contract from Petrobras for the acquisition of 3D and 4D data in the Campos Basin.

Irene Waage Basili, CEO of Shearwater GeoServices said that Brazil has one of the most advanced deepwater 4D seismic monitoring programs for reservoir management. This major seismic 4D towed streamer award from Petrobras adds a significant accrual to the substantial programs already awarded to Shearwater in Brazil, concludes the executive.

The state-owned company had previously started a seismic monitoring project in the Sapinhoá field, in the pre-salt layer, in the Santos Basin

Petrobras recently started the first of two seismic acquisitions in the Sapinhoá field monitoring project, in the Santos Basin pre-salt layer. Seismic acquisition is an important tool for managing the deposit (reservoirs) and optimizing production systems, seeking to maximize the value of assets by increasing the recovery factor of the deposits.

The new Petrobras surveys, in the pre-salt layer, in the Santos Basin, will use a technological solution called Ocean Bottom Nodes (OBN), which allows better collection of information from the deposit, from sensors installed on the ocean floor, to obtain better seismic response in geologically complex areas, such as the pre-salt layer.

Surveying 3D geophysical data at different times, or 4D acquisition, allows geoscientists and reservoir engineers to track fluid displacement, observe oil and water saturation variation, and identify effects of rock-fluid interaction and geomechanical behavior of the reservoirs, contributing to better management of oil recovery from the deposit and development of production in the Sapinhoá field, which is operated by Petrobras.

Petrobras has signed two contracts for the supply of flexible lines that will be used in the project to revitalize production in the Marlim and Voador fields, both located in the Campos Basin. Of the total 448 km of flexible lines in the project, 280 km were contracted with the company NOV and 168 km with Baker Hughes.

Between March and April, Petrobras signed contracts for the supply of up to 92 km of flexible gas lift lines (gasification of the production column) with the company NOV, and for the supply of up to 13 subsea production and injection manifolds, of which 8 with TechnipFMC and 5 with Baker Hughes, in addition to contracts for mooring materials, subsea equipment and umbilicals. Petrobras' initiatives are part of the revitalization project for Marlim and Voador, located in the Campos Basin, which aim to maximize the potential of these assets and promote greater return for the company and society, creating a virtuous cycle of value creation.
