Buenti Drilling Specialists

Drilling Services

Diamond Drilling


Diamond drilling consists of a solid core being extracted from a depth for examination on the surface.
Buenti Drilling has vast experience in the exploration of numerous minerals and offers NQ/NQ3, HQ/HQ3, and PQ/PQ3 sizes.


Reverse Circulation

Reverse circulation drilling is achieved by blowing air down the rods. The differential pressure creates an airlift.
The cuttings move up the inner tube inside each rod. They reach the top of the hole and move through a sample hose attached to the top of the cyclone.
The drill cuttings travel around the inside of the cyclone until they fall through an opening at the bottom and are collected in a sample bag.
Geosearch has immense experience in this field, with proven depth records.

Ultra deep Holes

Buenti Drilling has drilling rigs equipped to drill between 2500-4000m.

Large Diameter Code

Core sample quality is critical, and by drilling large diameter core holes, Buenti Drilling can provide a core recovery of 100%.
We provide 3m UWF core barrels to double the production rate. Core size 140mm; larger core sizes on request.

Mud Rotary Drilling

Mud rotary drilling can be described as a form of drilling most commonly used to create a stable hole in bad ground condition areas.
Buenti Drilling is fully equipped to perform these services at large diameters.

Percussion Drilling

Percussion drilling uses compressed air to drive a piston-driven hammer.
It delivers a series of impacts to the shank end of a drill rod or attached steel bit.

Water Well Drilling

Buenti Drilling has immense experience in water-well drilling and offers quality water-well construction services.
Sizes range from 6 to 20 inches. Larger sizes are available on request.

Aircore Drilling

The drill cuttings are removed by injecting compressed air into the hole via the annular area between the inner tube and the drill rod. The cuttings are then blown back to the surface up the inner tube, where they pass through the sample separating system and are collected as needed.

Auger Drilling

Auger drilling is done with a helical screw, which is driven into the ground with rotation.
The earth is lifted up the borehole by the blade of the screw.
We can offer 4 to 25 inches in size. Larger sizes are available on request.

Blast Hole

Buenti Drilling offers services for blast hole drilling using wheel-mounted and track-mounted drill rigs.
