Location: Aiken and Kahta Pipeline Sections (Properties of the North Montney Mainline)
Drill Rigs Committed: 3
Geotech participated on a pipeline investigation in Northeastern, British Columbia in 2013 and 2014. A total of 17 boreholes were completed on the Aiken portion of the program with an additional 22 boreholes drilled on the Kahta portion of the proposed pipeline route. Boreholes were completed with ODEX, mud rotary and HQ3 drilling techniques, while completing standard penetration testing and shelby tubes in overburden. On completion of the boreholes, Geotech installed various monitoring wells, slope inclinometers and vibrating wire piezometers. Further to the drilling program, Geotech was responsible for coordinating certain site services, such as, pad building (39+ pads), fuel storage and delivery and office space.
Challenging drilling conditions consisted of drilling during the winter season in subzero temperatures ranging from -30 to -50° Celsius, with helicopter portable drills. Due to the remoteness and weather conditions of the drill site(s), all water was flown into site and recaptured to reduce environmental impact, and to increase efficiency and utilization.
This program was successfully completed utilizing up to three drills, including two helicopter portable Hydracore 2000 drills and one track mounted Fraste MDXL drill.
