Why do we provide dewatering services?

We provide dewatering services to efficiently treat water to be recycled at the rig site as drill water or wash water, thus reducing waste volumes and minimizing environmental impact. Water usage is an increasingly important metric in today’s drilling projects.

What is dewatering & how does it work?

Water usage is an increasingly important metric in today’s drilling projects. Our dewatering technology uses flocculation and coagulation methods to provide up to 90 percent water recovery and can be applied to practically any water-based drilling fluid. We can adapt the system to any required rig specifications to extend these benefits.

Can Malcolm install a dewatering system?

In the most challenging subsurface conditions, Malcolm has the expertise and equipment to install dewatering systems. Malcolm’s fleet of modern drill rigs and drilling tools allow us to install wells through sands, gravels, cobbles, boulders, and rock, as well as under artesian conditions (groundwater under hydrostatic pressure).

What is dual rotary drilling?

Dual Rotary drilling is a method proven to be effective in challenging conditions such as drilling in unconsolidated and loose overburden material including glacial deposits, blasted rock, and industrial debris. Our Dual Rotary drilling rig, DR24, can set casing up to 24 inches (610 mm) in diameter and 500 feet deep. LARGE DIAMETER PRODUCTION WELLS: The Dual Rotary drilling method is used where conventional drilling techniques find challenges.

Which type of dewatering solution is best?

subsurface conditions, deep wells are often the most efficient and cost-effective dewatering solution. n the case of coarse-grained sands, gravels and cobbles, deep wells are often the only possible answer. Malcolm ha

How deep is a water well?

erally 15 to 25 feet deep and are constrained by the limits of vacuum to lift water out of the ground. They typically have a 3-foot-long slotted well
