As part of the due diligence work required to evaluate our SeaCure + QuikCure services for deepwater well, DeltaTek was recently asked to complete a rig site survey aboard the Pacific Khamsin 7th Generation UDW Drillship.
QuikCure builds on the SeaCure stabbed-in inner string cementing concept by circulating an engineered heat sweep (warm seawater) inside the casing to elevate the cement’s minimum environmental temperature and help rapidly build compressive strength.
The goal of the site survey was to confirm that the required heat sweep (around 1500 bbls of seawater heated up to +/- 60oC or 150oF) could safely and successfully be generated using the rig’s standard systems within a reasonable time-period, prior to the planned cement job.
To complete the rig site survey, our US-based project manager, Tyler Reynolds, travelled offshore to the rig from Port Fourchon, Louisiana.
Upon arrival, the rig crew helped us confirm the specifications and working configuration for the rig’s mud pumps, high-pressure lines including the mud manifolding, and shear gun units. We also took note of the layout and capacities for the mud pits and brine tanks available to our operation. Finally, we took photos of all the equipment that would be used to generate the requisite heat sweep used for a deepwater QuikCure application.
Using the information provided by the Pacific Khamsin crew, DeltaTek was able to confirm that the 1500bbl heat sweep could be safely generated using the rig’s systems. We were also able to estimate the time required and recommend configurations for which pits may need to be used being given access to one or both shear gun lines.
The client was appreciative of our efforts, and the exercise has given us some additional insight as to how we can operationally deliver our SeaCure + QuikCure services for deepwater projects moving forward.
