Although it's been nearly 40 years in the making, the casing while drilling technique seems to be entering a new phase, transforming from a thin niche to a larger slice of the drilling market, as fit-for-purpose tools become available and ideas for more applications build on earlier successes. The growing acceptance of Casing While Drilling (CWD) has spawned commercialization of related technologies to address issues ranging from casing running to new connections to formation evaluation. This has resulted in specialized rig designs, pipe-handling systems, logging and downhole tools, and software. Applications include extending casing points, drilling with surface conductor and underbalanced drilling – on both land and offshore – to name just a few.
