Petrobras Can Perform 3D and 4D Multiazimuth Seismic Research in the Albacora, Marlim, and Voador Fields in the Campos Basin

Petrobras recently received the operating license from Ibama (Brazilian Institute of Environment and Renewable Natural Resources) to conduct 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 agency 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 Conduct on Assets in the Campos Basin

Petrobras’s new research, for which Ibama issued the license, will be conducted using the SW Empress seismic vessel, owned by Shearwater GeoServices. In May, the seismic data acquisition company announced that it had secured this contract from Petrobras for acquiring 3D and 4D data in the Campos Basin.

Irene Waage Basili, CEO of Shearwater GeoServices, stated that Brazil has one of the most advanced 4D seismic monitoring programs in deep waters for reservoir management. This large 4D towed-streamer seismic award from Petrobras adds significant accumulation to the substantial programs already awarded to Shearwater in Brazil, concluded the executive.

The State Company Had Previously Started a Seismic Monitoring Project in the Sapinhoá Field in the Pre-Salt Layer of the Santos Basin

Petrobras recently began the first of two seismic data acquisitions for the monitoring project in the Sapinhoá field, in the pre-salt layer of the Santos Basin. Seismic acquisition is an important tool for managing the reservoir and optimizing production systems, aiming to maximize asset value by increasing recovery factors.

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

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

Petrobras has signed two contracts for the supply of flexible lines to be used in the revitalization project of 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 NOV and 168 km with Baker Hughes.

Between March and April, Petrobras signed supply contracts for up to 92 km of flexible lines for gas lift (gasification of the production column) with NOV, and for the supply of up to 13 subsea production and injection manifolds, with 8 from TechnipFMC and 5 from Baker Hughes, in addition to contracts for anchoring materials, subsea equipment, and umbilicals. Petrobras’s 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 returns for the company and society, creating a virtuous cycle of value generation.

Under kilometers of water, rock, and salt, Brazil hides a colossal wealth that led an official guide from the U.S. government to recognize the country as the owner of the largest ultra-deep oil reserves in the world.
