ExxonMobil contracts new 4D seismic study to improve Guyana offshore reservoir management

ExxonMobil contracts new 4D seismic study to improve Guyana……ExxonMobil Guyana has awarded a significant contract to Shearwater Geoservices for a comprehensive deepwater 4D ocean-bottom node (OBN) seismic survey. This initiative aims to enhance reservoir management and optimize hydrocarbon recovery in Guyana’s burgeoning offshore oil sector.

Scope and Objectives of the Seismic Survey

Scheduled to commence in the first half of 2025, the six-month survey will employ advanced seismic technologies to monitor subsurface changes over time. The primary objective is to acquire high-resolution data that will inform reservoir surveillance strategies, thereby improving the efficiency and safety of extraction operations. The deployment will include a Shearwater seismic vessel serving as the source vessel and a dual remotely operated vehicle (ROV) vessel for precise node placement on the seabed.

Strategic Importance for ExxonMobil and Guyana

This project underscores ExxonMobil’s commitment to leveraging cutting-edge technology to maximize the potential of Guyana’s offshore resources. The data obtained from the 4D OBN survey will provide critical insights into reservoir dynamics, enabling more informed decision-making regarding production strategies and field development. For Guyana, this translates into optimized resource utilization and increased economic benefits from its natural assets.

Technological Advancements and Methodology

The utilization of 4D seismic technology represents a significant advancement over traditional 3D surveys. By capturing time-lapse data, 4D seismic allows for the observation of fluid movements and pressure changes within the reservoir, offering a dynamic perspective that is crucial for effective reservoir management. The OBN approach enhances data quality by positioning sensors directly on the ocean floor, reducing noise and improving signal fidelity. This methodology is particularly advantageous in complex deepwater environments, where conventional seismic techniques may face limitations.

Shearwater Geoservices’ Role and Expertise

Shearwater Geoservices brings a wealth of experience in conducting large-scale seismic surveys in challenging offshore settings. Their recent successful completion of 4D towed streamer operations for ExxonMobil in Canada demonstrates their capability to deliver high-quality data acquisition services. The company’s state-of-the-art fleet and technological proficiency position them well to execute this ambitious project in Guyana’s rapidly evolving oil and gas sector.

Implications for Guyana’s Oil Production Trajectory

Guyana’s offshore oil industry has experienced remarkable growth, with production capacity projected to reach 940,000 barrels per day by 2025. The insights gained from this seismic survey are expected to play a pivotal role in sustaining and potentially increasing this upward trajectory. Enhanced reservoir understanding will facilitate more efficient extraction processes, contributing to the country’s economic development and energy security.

Environmental and Regulatory Considerations

Conducting seismic surveys in sensitive marine environments necessitates stringent adherence to environmental regulations. ExxonMobil and Shearwater are expected to implement comprehensive environmental management plans to mitigate potential impacts on marine life and ecosystems. This includes measures such as real-time monitoring, the use of marine mammal observers, and adherence to best practices in noise reduction during seismic operations.

Conclusion

The collaboration between ExxonMobil Guyana and Shearwater Geoservices for this extensive 4D OBN seismic survey marks a significant milestone in the advancement of Guyana’s offshore oil capabilities. By integrating sophisticated seismic technologies with experienced operational execution, the project aims to enhance reservoir management, optimize production, and contribute to the sustainable development of Guyana’s valuable hydrocarbon resources.
