Drilling

BHM has extensive expertise in drainage drilling, deep cooling and injection well construction.

Our recirculation drilling method, which is particularly advantageous in controlling the flow of water in urban areas, has proven to be most effective.

Drilling Teams and Equipment

Our drilling teams are experienced in constructing wells in many types of strata, ranging from cohesive to igneous formations, while at all times keeping in mind the importance of safety and using responsible working methods to respect the local environment and communities.

Our fleet of Atlas-Copco TW2 & TW4 model drill rigs are capable of being used for direct drilling using the re-circulation method to depths in excess of 1560 feet, with the additional capability to obtain core specimens using rotary drilling. A typical drainage well construction is 10 inch in diameter and 215 feet deep, with PVC liners installed and grouted into place at specified depths, according to site conditions and client requirements.

Drilling Experience

BHM also has a wealth of experience in deep wells exceeding 660 feet deep and 4 feet in diameter. These deep wells have strict requirements on plumb and alignment, along with other requirements. Such requirements include keeping contractual relevant drilling records, obtaining and storing samples of strata encountered, obtaining and storing ground-water samples, obtaining core samples by rotary drilling, developing wells to acceptable levels of turbidity, conducting water quality analysis, and commissioning and assisting with the geophysical and flow capacity testing and video surveys.
