INROCK®
supplies a modular steerable jetting assembly. It differs from
standard jetting tools by expanding the formation hardness range
of jetting applications to short rock sections, occasional boulders
and intermittent "hard" spots. This is accomplished
by utilizing a jetted rock bit in conjunction with a bent/extension
sub. The assembly is used in the same manner as a standard jetting
assembly...rotate to drill straight ahead, or stop rotating
and jet ahead to make steering corrections. When a hard section
is encountered, the rock bit is rotated. Directional control
is resumed when softer formations are entered. INROCK®'s
Steerable Jetting Assembly is compatible with Walkover Guidance
Systems or Wireline Guidance Systems, and is available in several
size ranges to drill pilot holes from 3-1/2" to 12-1/4"
diameters.
