Revolutionizing Offshore Well Abandonment for Carbon and Hydrogen Storage
Key Ideas
  • Aquaterra Energy launches a new service utilizing the Recoverable Abandonment Frame (RAF) to re-enter and re-abandon legacy wells, specifically targeted for CO2 and hydrogen storage projects.
  • The technology overcomes economic and technical challenges by precisely locating wells, employing seabed and subsurface surveying technologies, and protecting legacy well components during re-abandonment.
  • The solution offers cost savings of up to £18-20 million per abandoned well, reduces project timelines by up to 50% per well, and enhances the viability of carbon and hydrogen storage projects.
  • Discussions are underway with oil and gas operators and CCS specialists globally to implement Aquaterra Energy's services and RAF technology in regions like the North Sea and APAC.
Aquaterra Energy has introduced a groundbreaking solution for offshore well abandonment tailored for carbon dioxide (CO2) and hydrogen storage projects. The new patent-pending Recoverable Abandonment Frame (RAF) and well re-entry services aim to address challenges associated with repurposing legacy wells that intersect offshore oil and gas reservoirs or saline aquifers. These legacy wells pose leakage risks beneath the seabed, potentially hindering carbon capture and storage (CCS) and hydrogen storage initiatives. By utilizing advanced surveying technologies, the RAF precisely locates wells and facilitates re-abandonment using a vertical tieback method, protecting the well components from environmental loading. CEO George Morrison highlighted the company's commitment to innovation and tackling energy transition challenges. Aquaterra Energy's technology, designed for repeated use across various seabed conditions, offers significant cost savings of £18-20 million per abandoned well and reduces project timelines by up to 50% per well. Innovation Director Ben Cannell emphasized the efficiency and viability of the solution, crucial for enabling costly or previously unfeasible carbon and hydrogen storage projects. The company is actively engaging with major oil and gas operators and CCS specialists globally to deploy their services and RAF technology. Discussions are underway for potential deployments in regions such as the North Sea and APAC, showcasing the technology's potential impact on the industry's operational efficiency and environmental sustainability.
