In 2006, a coiled-tubing-drilling (CTD) pilot program was initiated in the San Juan basin consisting of seven wells, drilled in order of increasing complexity. The intention was to evaluate the capabilities of CTD and its potential for use in the San Juan basin. The rig used was a new, custom-built, coiled tubing (CT)/rotary hybrid rig with a single-sized derrick, rotary table, and topdrive. This setup allowed the rig to drill with jointed pipe, handle and make up BHAs, and run liners and casing.
