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 allowed the rig to drill with jointed pipe;
handle and make up bottomhole assemblies (BHAs);
and run liners and casing;
