In 2015, a major Canadian natural gas distribution company had to perform construction operations to upgrade its existing distribution system. To mitigate the disturbance of the surface level roads and natural habitats, the proponent utilized horizontal directional drilling (HDD) technology. Twenty large bores (36" and 42") were planned for this project.
The Georgian Bay Pipeline Project was necessary to meet growing need for natural gas in that region. The new pipeline was 20 kilometers and 12” diameter. The route for the pipe included 30 road, rail and river crossings which would require horizontal directional drilling (HDD) to complete. Spent HDD fluids and cuttings are a regulated waste in Ontario and very costly to transport and dispose of. An estimated 250,000 gallons (940,000 litres) of spent drill mud would be in need of disposal.
Drilling waste in BC in need of solidification at remote mountain top site. Drilling mud produced near slopes estimated at greater than 28⁰ restricting mobility and truck access. Project deadline was constrained by heavy rain prior to mobilization and wildlife migration and fisheries preservation. Thin layers of gravel-like natural soil provided inadequate soil properties for mix-bury-cover site processing.
Large volume of oil and gas exploration drilling fluid stored in drill mud sump to be solidified in severe cold in Fort McMurray, AB in January. Long distance to liquids disposal site made liquid transport and disposal costs extremely high. After treatment, the solidified waste drill fluids were transported to a solids disposal site saving approximately 8 hours per load.
MetaFLO's licensee was contracted to provide service on a large Ontario gas distribution upgrade project. Nearly 50 bores were drilled using horizontal directional drilling technology to complete this upgrade. MetaFLO's licensee was required to process the resulting liquid waste which totaled more than 500,000 gallons of directional drill mud.
