The latest edition of Drilling Contractor Magazine focuses on cementing, which can be one of the more challenging parts of the well-construction process. The editors have included an article on how the CML/EC-Drill technology can add value. With the varying fluid densities and changes in OD required during a cementing operation, this is an area where the difference between an MPD system like CML/EC-Drill which uses over-balanced fluids only and other MPD systems relying on under-balanced fluids often become rather apparent in terms of the required complexity and associated online rig-time usage.
