Home \ Solutions \ Blue hydrogen and CCS Repurposing offshore assets to support the blue hydrogen and CCS economy The energy transition is placing hydrogen centre-stage, and carbon capture and storage (CCS) is critical for a successful blue hydrogen supply chain (and for other carbon-generating industries). In this new context, mature oilfields are newly useful, and depleted reservoirs become valuable storage assets. However, there are a number of critical engineering considerations and competencies required in successfully repurposing legacy wells as carbon storage. Even correctly suspended or abandoned wells may not be suitable for underground CO2 storage due to barrier selection and testing – at least not without drilling costly relief or intersection wells. New applications, proven track record We can help eliminate these risks with our field-proven well re-entry and tieback engineering products and services. Our track record is second-to-none, spanning over 500 wells engaged and over 100 years’ in-house experience. A tried and tested equipment and service portfolio Our portfolio of equipment and solutions already helps oil and gas operators globally accelerate time to first oil, reduce rig time and drive cost efficiencies for well, intervention and workover projects. This knowledge and expertise can be applied to blue hydrogen and CCS projects. For example, using our Sea Swift platform for blue hydrogen projects in shallower waters where operators need to drill multiple vertical wells vs. a traditional fixed based platform. Every well is unique No two wells are the same, and each re-entry has its own challenges. Lack of well data, damaged tieback connectors, cut or below-mudline connectors and well-integrity issues are just some of the obstacles we’ve encountered and surmounted. With careful planning and an intelligent approach, even the most problematic legacy wells can be safely re-entered for CCS applications. Products Sea Swift platform Our flagship Sea Swift minimum facilities platform offers rapid returns in shallow waters. The platform design minimses build and implementation times to reduce capex and time to first oil.
