Challenge:

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.

Solution:

MetaFLO Technologies provided on site solidification of what became 300,000 gallons of mud. At an average 12 pounds per gallon, total waste was approximately 1,800 tonne. The solidified mud was piled in holding berms and turned twice a day to achieve greater volume reduction through evaporation.

Result:

We initially estimated a savings to Enbridge of 30% versus transportation to liquid disposal sites. Additional volume reduction got the solidified waste volume down to 1,386 tonnes for additional 23% cost savings. MetaFLO’s technology eliminates liquid waste bulking which would otherwise take up additional space in our increasingly scarce landfills.
