Driller for major gas distributor requires cost effective solution for disposing of drilling waste in Quebec near Pierre Elliott Trudeau International Airport. The drill site was in an urban setting with high traffic volume. Drill spoils waste was too liquid and would not be accepted by local disposal site. The Ministry of Sustainable Development, Environment and the Fight against Climate Change requires treatment of liquid drilling waste in Quebec as liquid industrial waste. With only small sumps on site and nearly 1,000m3 of waste, a quick and cost effective disposal option was needed.


After assessing several solutions, solidification on site using MetaFLO’s MF006 mechanical solidification reagent was chosen. The plan was to solidify the drilling fluids on site to achieve the required solids criteria. After solidification, our client would be able to ship the waste using dump trucks for disposal at the nearby solids disposal facility. Shipping and disposal of the liquid drill waste would have been more costly, meant greater risk and had a greater environmental footprint.


The solidification process was a success. All of the mud was solidified quickly and accepted by the solids waste receiver. Cost was reduced due to the lower cost of dump trucks and solids disposal. Additionally, solids allow for larger volume per truck reducing the project’s carbon footprint and safety risks.
