Prioritize Tieback Mobilisation, Floating Power Options and CCS Risk

Shell and Kosmos Energy have sanctioned the Trailblazer exploration well in the US Gulf of Mexico, targeting a prospect estimated to contain about 200 MMboe and potentially setting up another subsea tieback to Shell's Appomattox production hub. Shell plans to drill the ~200 MMboe Trailblazer prospect early next year in the Norphlet trend in the US Gulf, partner Kosmos Energy said in a results update

SolarDuck’s approach reduces costs associated with long-distance subsea umbilicals, especially as tieback distances increase. The floating power hub can support a range of offshore applications, from subsea production to CCS developments and remote assets

SolarDuck says its offshore floating power hub, combining floating solar, battery storage and auxiliary generation, could offer a lower-cost alternative to long subsea umbilicals while supplying power, communications and other utilities to remote offshore assets

Cannell: Clearly, if CCS is to achieve its core aim, injected CO2 has to remain securely contained over the long term, and legacy wells are one of the key areas that must be effectively managed to ensure this happens

Wells within or close to the predicted plume path should be prioritized, particularly where there is limited confidence in existing barriers. Where a well presents a potential containment risk, operators need to consider re-abandonment, relocating injection wells, reducing injection volumes or adding further monitoring

Operators can expect strong scrutiny around well integrity, legacy well assessment, monitoring plans and risk reduction measures

According to Well-Safe, integrating subsurface engineering with well management services can help operators identify cost and risk reduction opportunities while improving P&A planning and execution. The companies also said the collaboration should provide greater certainty during decommissioning strategy development and operational delivery

Well-Safe Solutions has signed a partnership agreement with Islay Subsurface & Engineering that includes support for the recently awarded Beryl and Forties decommissioning programs in the UK central North Sea. Under the agreement, Islay will provide subsurface expertise spanning geology, petrophysics, geophysics and reservoir engineering, complementing Well-Safe Solutions' well life-cycle management and plugging and abandonment (P&A) capabilities
