Drilling Through Solid Rock: Tooling & Technique

When the geotech report says rock, most boring companies walk away. Here's the downhole tooling that lets us finish the bore.

Why Rock Bores Separate the Pros from the Rest

Solid rock formations stop underpowered rigs and dull tooling dead in their tracks. The key is matching the right rock bit and mud program to the formation.

Tooling Selection

We carry a range of tri-cone and PDC bits tailored to compressive strength. A proper bent housing keeps the pilot bore on grade through hard seams.

Mud Program

Bentonite viscosity and flow rate matter most in rock — too thin and cuttings settle, too thick and you risk sticking the drill string. Our fluid engineers dial it in per formation.
