Supporting safe re-entry into legacy well formations for offshore storage of CO2 for carbon capture and storage developments.
We have designed our legacy well re-entry service suite to be a specialised resource for facilitating safe re-entry into well formations for the offshore storage of CO2; crucial for advancing carbon capture and storage (CCS) initiatives. At Aquaterra, we are wholly committed to safe and efficient CO2 storage. Our recent contract with INEOS on Project Greensand highlights our commitment to meeting worldwide CCS goals.
Repurposing depleted oil reservoirs and saline aquifers makes practical sense, as they are typically situated within mature basins and come with detailed geological data. However, they do present unknown leakage risks. Before CO2 injection can begin, these wells must undergo re-entry to establish an environmental and pressure-retaining barrier, ensuring safe re-abandonment and readiness for storage.
Drawing upon decades of expertise in well re-entry and tieback engineering from the oil and gas industry, we provide tailored solutions for repurposing depleted reservoirs and saline aquifers to store CO2 effectively.
Our well re-entry and feasibility studies assist CCS operators in identifying suitable wells for re-entry, mitigating risks, and devising optimal methodologies for re-abandonment. This includes:
We specialise in creating robust pressure-retaining barriers below the mudline, utilising our tieback engineering expertise to ensure the long-term integrity of CO2 storage wells.
Our experienced team of engineers specialise in developing robust well re-entry plans and providing the necessary, recoverable equipment and expertise to ensure a successful re-entry and tieback operation. The outcome is a properly re-abandoned well that facilitates long-term CO2 storage. This is just one example of exciting CCS technology that will help the UK achieve its goal of capturing 10Mt of carbon dioxide a year by 2030.
Our dedicated team of offshore tieback analysts provides site-specific reviews, incorporating legacy well re-entry data and information, environmental conditions, and rig specifications to optimise strategies and approaches.
The Recoverable Abandonment Frame (RAF) is an innovative, cost-effective vertical well re-entry solution designed to reduce costs and project timelines, making offshore carbon capture and storage (CCS) and hydrogen storage projects more viable.
The RAF is a specially designed steel frame that can be positioned precisely over a well, enabling safe vertical re-entry. The frame provides structural support for all intervention equipment, keeping the weight off the well to avoid damaging any corroded casings. Its unique movement mechanism allows for adjustments to account for installation tolerances.
The frame is accurately positioned over the well, accounting for installation tolerances.
It reacts loads away from the legacy well, preserving the integrity of unknown or compromised casings.
Enables the establishment of environmental and pressure-retaining barriers, facilitating safe and efficient well re-abandonment.
It protects corroded well casings by supporting intervention equipment and avoiding additional loads.
Rapidly installs barriers to prevent sediment intrusion and secure the well for re-plugging.
Can be redeployed across multiple wells, maximising cost-effectiveness without additional investment.
Minimises risks, regulatory delays, and the need for complex, costly alternatives.
