The numerous oil and gas leases west of Valleyview, Alberta are maintained by various companies and are continually being expanded and connected to the local pipeline network. As part of this expansion, additional pipeline segments were planned with some watercourse crossings requiring horizontal directional drilling (HDD) to complete. After a number of “frac outs” and the abandonment of a nearly completed HDD crossing due to groundwater issues, Matrix was retained to perform site-specific hydrogeological assessments. Our team used these assessments to conduct a risk ranking and provide mitigative measures for the subsequent planned pipeline crossings.
