DeltaTek launched its SeaCure services in 2018 and has gone on to deploy the technology on multiple new wells in the UK North Sea and the Mediterranean. DeltaTek has been vocal about the time and cost-saving benefits of the technology (up to 80% in some cases), but something that we don’t often discuss is the environmental impact.
“Cement manufacture is one of our biggest contributors to wells carbon budgets” – a North Sea operator.
Manufacturing of oilfield cement results in substantial emissions of carbon dioxide from the industrial processes involved. While manufacturers and operators have been seeking ways to reduce this or to capture the carbon produced, and to make cement production more energy-efficient, the results have failed to keep pace with the need to cut carbon emissions.
What are the environmental benefits of SeaCure?
The traditional cost-saving benefits of saving rig time through quicker deployments, combined with our ability to reduce wait on cement time (WOC) when combining our SeaCure technology with QuikCure are some of the more obvious benefits, but each SeaCure deployment has also had a significant environmental impact.
In one project on Siccar Point’s Lyon field off the West of Shetland, in collaboration with The Oil and Gas Technology Centre, DeltaTek was brought in to deploy a solution to offset difficulties with traditional cementing methods.
Clinical execution of the SeaCure cementing system resulted in delivering both 30” conductor and 20” surface casing cement jobs with significant reductions in cement waste, saving approximately 100MT of CO2 emissions through this reduced cement usage alone.
As operators move towards the goal of Net Zero, combined with an effort to reduce operational costs, it is key that they look at solutions that can deliver both.
DeltaTek’s SeaCure technology has proven its ability to benefit operators with substantial reductions in cement wastage, and therefore CO2 emissions on every single deployment.
