The operator set a strategic target to achieve net zero carbon emissions by 2040.
As part of this initiative, it was key for the operator to review their existing asset portfolio and infrastructure to evaluate the options available for safely converting existing producing assets into carbon sequestration opportunities.
Oil and Gas operator
1 aging production facility and 15 offshore wells: 50% were active producing wells, 40% were plugged and abandoned, 10% were in the process of decommissioning
To risk assess an onshore production facility and a collection of offshore wells (a mix of wells that had been plugged and abandoned, were still producing or were in the process of decommissioning) to determine their viability and capability to safely and permanently store CO2.
In essence, we were tasked with determining:
Due to the unique nature of this work, and with a lack of capability or expertise to conduct this study in-house, the operator required expert support.
The complexity of the wells and the risk of incident were extremely high and severe enough to justify outsourcing this work to Add Energy’s experts in this field.
As subject matter experts in well integrity and with an already established relationship with the operator in place, Add Energy was selected as the “go-to” specialist to provide trusted expertise and guidance on how to successfully maximize carbon sequestration opportunities.
To deliver this highly complex and vital assessment the team adhered to the following process:
Add Energy presented the technical assessment results and recommended actions required to convert the wells within a detailed engineering report.
Of the 15 wells that were evaluated as part of this feasibility study, Add Energy found:
11 “suitable” wells that:
4 “unsuitable” wells that:
Provided independent verification of the wells integrity and capability to withstand CO2 injection, by subject matter experts
Strategy and Compliance
Offered a clear understanding of the requirements needed to convert existing wells to CO2 storage well, while assuring well integrity and compliance with international standards
Delivered a time-efficient solution to understanding requirements and feasibility to reduce carbon emissions, offering insights and advice in a matter of months
Assured compliance through assessment against international standards and regulations, enabling safety to be upheld
Delivered a cost-effective solution, enabling the operator to save 60% on costs by outsourcing this study to independent experts, when compared to completing the study in-house
