About the GEFCO 40K

The GEFCO 40K sits above the 30K in the GEFCO lineup — stepping up to 40,000 lbs of pullback and hold back, with air compressor options reaching 1250 cfm at 350 psi. This additional capacity opens the door to larger casing diameters, deeper formations, and more aggressive drilling programs.

The 2024 generation of the 40K ships on Peterbilt 589 and Western Star 49X carriers and can be specified with telematics for remote monitoring. The casing hammer option on the 40K handles larger-diameter casing than the 30K system, making it the preferred choice for larger municipal wells and geothermal applications requiring 16–24" casing.

The 40K has a strong international demand profile. Export buyers — particularly in Africa and the Middle East — favour the 40K over the 30K for its greater capability and resale longevity in high-demand environments.

GEFCO (now Bauer Equipment America) continues active production in 2024, which keeps the new-build option accessible and provides strong dealer support for used units.

Who Buys GEFCO 40K Rigs

Large Municipal Wells

High-volume city water supply wells. Greater casing capacity means larger bores for municipal flow rates.

Geothermal (Large Scale)

District heating bores and commercial geothermal — deeper and larger diameter than the 30K can handle.

🌍

Export / International

Strong demand from Africa, Middle East, Asia. The 40K's reputation and parts support makes it the preferred export rig.

⛏️

Mining Water Supply

High-capacity dewatering and process water wells at mine sites — the 40K's air volume handles hard rock efficiently.

🌾

Commercial Agriculture

Large-scale irrigation wells needing bigger casing and higher yields than residential drillers require.

💼

Fleet Expansion

Contractors adding a heavier rig to complement their 30K fleet for larger contracts.
