Innovative Solution for Legacy Well Re-Entry and Re-Abandonment in Offshore Energy Transition
Key Ideas
  • Aquaterra Energy introduced a new patent-pending Recoverable Abandonment Frame (RAF) to address challenges in re-entering and re-abandoning legacy wells for carbon dioxide or hydrogen storage.
  • The RAF employs advanced surveying technologies to locate wells precisely, enabling successful re-abandonment via a vertical well re-entry tieback method while protecting components from environmental loading.
  • The technology offers flexibility for different seabed conditions, can be shipped worldwide for multiple well applications, and is estimated to save operators £18-20 million per abandoned well with an 80% reduction in costs compared to current methods.
  • The innovative solution not only lowers costs but also reduces project timelines by up to 50%, making carbon and hydrogen storage projects more viable and efficient, ultimately contributing to the energy transition goals.
Aquaterra Energy, a leading offshore engineering solutions provider, has unveiled a groundbreaking solution for addressing the challenges associated with legacy well re-entry and re-abandonment in offshore environments. The introduction of the Recoverable Abandonment Frame (RAF), a patent-pending technology, aims to facilitate the repurposing of offshore oil and gas reservoirs or saline aquifers for carbon dioxide (CO2) or hydrogen storage. Legacy wells that penetrate these formations pose significant economic and technical challenges, especially in the context of carbon capture and storage (CCS) and hydrogen storage projects. Traditional relief well drilling methods may not always be feasible, leading to potential environmental, safety, and regulatory issues. Aquaterra Energy's RAF solution utilizes advanced surveying technologies to precisely locate wells, enabling the re-engagement and successful re-abandonment of legacy wells with enhanced safety measures. The RAF's innovative design not only safeguards the well components during the re-abandonment process but also offers cost-saving benefits for operators. Estimated to save £18-20 million per abandoned well, the RAF technology presents an 80% reduction in costs compared to existing methods. Additionally, this solution can significantly reduce project timelines by up to 50%, making carbon and hydrogen storage projects more efficient and economically viable. By leveraging decades of offshore expertise, Aquaterra Energy aims to support the energy transition by providing a reliable and efficient solution for legacy well re-entry. The company's commitment to innovation and sustainability is further demonstrated through discussions with major oil and gas operators and CCS specialists for the deployment of this cutting-edge technology in various global regions.
