Delivering low-risk, high-value cementing operations.
Drilling shoetracks takes time, can introduce problems and increases risk. Placing cement in a casing annulus in a subsea environment using a poor boy inner string stinger technique can introduce complexities with less than optimal fluid interfaces, fluid velocities, generate contamination in a cement job and result in lengthy setting times at low ambient temperatures.
Following a successful deployment, supported through the Oil and Gas Technology Centre (OGTC), on Siccar Point Energy’s Blackrock field, DeltaTek’s propriety technology – SeaCure – had been selected for the 30â€ and 20â€ casings on the Siccar Point Lyon project. Learning from experience of non-bump problems when using traditional SSR plug technology in previous surface casing operations and suffering the associated drill out inefficiencies, SeaCure was brought in to mitigate these common issues, delivering excellent results.
SeaCure uses stabbed in inner string cementing for subsea wells, eliminating shoetracks, optimising cement placement and improving reliability of pressure testing subsea casing strings. Taking the proven onshore technology of stabbed in inner string and combining them with slip-joint and rupture disc technology, a step change in subsea well cementing has been developed. QuikCure combines SeaCure with a post cement job heat sweep internal to the casing bore, delivering dramatic early compressive strength development of cement for rapid continuation of operations and solid life of well foundations.
Minimise risk, reduce environmental impact, increase saving on rig time. Hear from DeltaTek CEO, Tristam Horn, about how SeaCure and QuikCure solves a number of key issues while saving rig time.
Aged just 27, Tristam founded DeltaTek in 2015, in response to a growing need for intelligent, efficiently implemented, and cost-saving solutions to common problems in the offshore cementing process. Having spent five years working in various drilling engineer and supervisory positions in the North Sea, Angola and the Gulf of Mexico, Tristam identified several recurring issues, which would eventually lead to him identifying a solution.
Drawing inspiration from other sectors within the oil and gas industry, Tristam has developed techniques from these other sectors to create solutions suitable for both shallow and deep-water well cementing.
Since establishing the company four years ago, Tristam has availed himself of the knowledge and experience provided by Elevator programmes, before securing funding from the OGTC and Scottish Enterprise, allowing DeltaTek to conduct both onshore and offshore field trials with Chevron and Siccar Point Energy throughout 2018 and into 2019, and going on to win a number of commercial jobs.
