DeltaTek Global, the well construction specialist, has started trials of its SeaCure subsea cementing system.
The company completed two onshore field trials of the SeaCure, resulting in subsequent offshore trials with two North Sea operators this summer, as part of a project backed by the Oil & Gas Technology Centre.
SeaCure is a subsea cementing system, delivering stabbed in inner string cementing for subsea wells. SeaCure’s initial ‘proof of concept’ trials took place in April at an onshore test well at Frank’s International’s Aberdeen base.
These will be followed this summer by three offshore trials in live North Sea wells operated by Chevron and Siccar Point Energy, down to a water depth of 5,000ft,, the company informed.
The trials are expected to lead to a full product launch in September.
Tristam Horn , CEO and founder of DeltaTek, said: “The success of these trials clearly illustrates DeltaTek’s fundamental ethos; to save rig time by providing a number of genuinely unique value propositions to drilling operators. We are delighted to have the support of Chevron and Siccar Point Energy for the trials in live wells.
“With the ability to undertake offshore cement jobs in any range of water depths, SeaCure’s inherent benefits include improved success rates of cement placement back to the seabed for conductor and surface casings, performing a pressure test of a subsea casing string prior to and post cementation, as well as entirely eliminating a clean-out run from a subsea drilling programme.”
Malcolm Banks , Well Construction Solution Centre manager for the Oil & Gas Technology Centre, added: “We are impressed with the progress of the SeaCure technology. There was strong operator interest from the outset and the successful onshore deployment means we can progress the project to live offshore trials later this year. ”
