Capabilities

Key Advantages

01

SCR DC Drive System

Dual Caterpillar 3512C engines paired with a Ross Hill 3-Bay SCR house deliver reliable, variable-speed DC power through 752-motor drawworks and Emsco triplex pumps — a proven configuration for extended drilling campaigns.

02

Hydraulic Walking

Factory hydraulic walking system eliminates costly rig move time between pad locations, reducing non-productive time and maximizing operational efficiency on multi-well pad programs.

03

Full Solids Control Train

Complete Brandt desander/desilter, dual Derrick 504 linear-motion shakers, Derrick Drilco degasser, and a closed-loop 560-barrel mud system support continuous drilling without interruption.
