OUR DRILLING METHODS
Hollow Stem Auger Drilling
Hollow Stem Augers are used for unconsolidated soils, wet conditions and monitoring well installations. These are used when formations are prone to collapse. Hollow stem augers are a larger diameter, making for a slower process and greater amount of cuttings.
Solid Stem Auger Drilling
Solid Stem Augers are used primarily for drilling in consolidated soils. They are effective in soft to medium formations and are a great tool for creating small diameter boreholes without introducing any fluids. Solid stem augering is not effective in formations prone to collapse.
Rotary Mud Drilling
As its name suggests, mud rotary drilling uses a sharp, rotating drill bit to create boreholes in conjunction with mud to stabilize, remove cuttings, suppress downhole water, and lubricate the drilling string. Landcore Drilling carries a wide variety of drilling muds including a polymer and additive free mud for environmentally sensitive tasks. Mud rotary drilling rigs are designed to drill a hole with a high penetration rate, making them extremely useful for deep exploration applications.
Wireline Coring (NQ, HQ, PQ)
In wireline core drilling, a piece of equipment called an overshot is sent down the hole to release and retrieve the inner tube. The overshot and inner tube are then brought up to the surface using a wireline hoist, allowing the rods and core bit to remain in the hole. A new inner tube is then lowered down and locked into place to continue drilling.
Limited Access (Portable) Drilling
Our limited access drilling division is at the forefront of the drilling industry. From areas where a typical soils drill cannot access to inside of a building, we have a solution for you. In these tight situations we can still perform all types and methods of sampling, testing and well installations.
