In order to meet the Canadian military’s potable water needs, ALTECH Drilling and Investigative Services in Cambridge, Ontario, Canada, performed hydrogeological investigations at the 5 Wing Practice Training Area in Newfoundland and Labrador in northern Canada.
The project was not short on challenges. “We knew there were no access roads to the facility, and with so many geologic unknowns, we knew we needed a drill capable of tackling a variety of drilling applications,” said Tyler Yensen, Managing Partner for ALTECH Drilling. “It needed to be a lightweight drilling machine, capable of flying on a C-130, and versatile enough to perform any drilling applications the Canadian north would require.” The scope of work included the ability to drill 35 feet of overburden and 50 feet into bedrock. They were also required to drill numerous sand points to 35 feet. “We figured our 7822DT was the right machine for the job,” Tyler said.
“We assembled a team based on previous Geoprobe® drilling experience and most important, the ability to solve problems. A trip to the drilling supplier was not an option here. Brandon Stranz and his team accomplished the goals of the Canadian military and then some. Great work, team!”

A CC-130 J Hercules was used to transport the ALTECH field team, supplies and the rig to the training facility about 100 km southwest of Goose Bay. While at the site, the field team performed hydrogeological investigations including deep bedrock drilling using mud rotary techniques to install observation wells. Tyler stated the first 40 feet was a wet sand and silt formation, then they hit bedrock at 40 feet. “We used DT45 tooling (dual tube 4.5 in. diameter) to accomplish the overburden,” he said, “then mud rotary to tackle the rock.” ALTECH was onsite for two campaigns, approximately six days each. Various pumping tests were also completed.
