Capabilities

Key Advantages

01

Triple Cat 3512C SCR Power

Three Caterpillar 3512C generators at 1,365 kW each feed a Ross Hill 3×4 bay SCR house, delivering stable DC power to the Davis 1500-E drawworks and twin 3-F-1600 triplex pumps at 7,500 psi.

02

Walking System Ready

Columbia In-Sub Walking System with HPU enables pad drilling without rigging down — a competitive capability on multi-well pad locations.

03

350-Ton Top Drive

The 350-ton Warrior hydraulic top drive with 7,500 psi circulation rating adds directional drilling capability and reduces connection time compared to conventional kelly systems.
