HORIZONTAL DRILLING FOR DEPRESSURIZING/SUPPLY
Our dedicated horizontal drill rigs effectively relieve high-wall pressure with holes drilled at a +/- 5-degree angle, creating an outlet for water to drain. Our horizontal drilling rigs are highly engineered and certified FOB rated.

DUAL TUBE FLOODED REVERSE
This unique drilling process uses dual wall drill pipe and drilling fluid along with the injection of air in order to drill large diameter holes. In the drill string, perforations allow the air to return up the center, following the path of least resistance. The air traveling back up the inner tube creates a vacuum, which in turn sucks up the cuttings from the bottom of the hole at the face of the bit. Using Dual Tube Flooded Reverse (DTFR), fluids always circulate inside the dual tube pipe and cannot escape into the formation. Instead of maintaining fluids at the surface and circulating throughout the wellbore, DTFR generally drills with the borehole fluids at their naturally occurring level.

DEWATERING
Our diverse fleet of dewatering rigs includes various sizes with capabilities to drill wells up to 152.4 centimeters (60 inches) in diameter and depths over 2,438 meters (8,000 feet).

POTABLE WELLS
Boart Longyear capabilities include potable wells which are larger drilled wells to completion between 30.5-45.7 centimeters (12-18 inches) and depths over 914 meters (3,000 feet).

INJECTION/ARTIFICIAL STORAGE AND RECHARGE WELLS
Our capabilities for injection wells include large or small diameter, with depths of up to 2,438 meters (8,000 feet).

ANGLE WELLS
Using a unique bottom hole assembly to drill angle water wells in order to achieve the desired target, Boart Longyear is also capable of drilling through multiple vertical water-bearing fractures.

GEOTHERMAL WELLS
Boart Longyear provides experienced crews in geothermal well systems. We provide geothermal well installations includ­ing drilling, set up, casing installation, and blowout preventer equipment installation. Additional services include the remov­al of geothermal wells systems for replacement or repair. Boart Longyear has performed work in places such as Fallon, Nevada; Lightning Dock, New Mexico; Raft River, Idaho; and Neal Hot Springs, Oregon. Let us help you with your next geothermal well installation or repair/replacement project.
