Cable ***** using percussion-type tools and those that clean the hole using tubular-type bailing tools. Portable drilling rigs.Drills mounted on a carrier and used on the surface (above ground). Pull-back capacity.Lifting capacity of drawworks or hoisting capacity of taphead. Pull-down ***** to apply bit pressure. Reverse ***** using a rotary drilling process where the drill cuttings and fluid return to the sur- face inside the drill stem (large diameter holes, *8 or larger). Rotary ***** using rotary drill pipe, continu- ous fluid, and a mud pump, air compressor, or combina- tion to clear the hole of filling.
