Pipeline Drilling Waste Disposal Options
The location of the pipeline construction typically will dictate what type of drilling waste disposal will be the best option. In agriculture areas where cultivated lands are available, offsite disposal methods such as LWD may be the most time and cost efficient. In forested areas, where transportation is timely and exspensive, disposing of the drilling waste via Landspread on Pipeline Right of Way may be the best method of disposal. If a sump is used for storage prior to commencement of drilling operations it is crucial that the disposal methods that will be used are investigated and confirmed to ensure that there is no confusion which may cause delay or non-compliance.
Landspread On Lease/Pipeline Right Of Way: A drilling waste disposal method that involves applying the drilling waste at a calculated application rate and incorporating into the shallow subsoil.
Mix Bury Cover: A drilling waste disposal method that involves mixing the drilling waste with the subsoil at a predetermined mix ratio and capping the resulting soil/waste mix with a minimum or 1m of clean parent material.
Landspray: A drilling waste disposal method that involves storing non-toxic, water based drilling waste fluids or total waste before dispersing onto a field by spraying at a specified, constant rate from a vacuum truck or similar equipment. Testing and supervision will be completed by a Wellsite Environmental Inc. field consultant.
Landspray While Drilling (LWD): A drilling waste disposal method that involves the dispersion of non-toxic, water based drilling waste fluids or total waste onto a field by spraying at a specified, constant rate from a vacuum truck. Management and supervision of all LWD activities will be completed by the Wellsite Environmental Inc. field consultant which also includes arranging and sampling for application on applicable lands.
Sump Sampling and Disposal Management: Involves collecting samples from any sumps acting as storage systems for drilling waste to determine a disposal management plan that meets criteria set out by applicable governmental regulations.
Pump Off Operations: A disposal method that involves pumping the non-toxic, clear liquid portion of drilling waste from sumps onto a land surface that meets applicable provincial regulations and criteria.
Cuttings Management-Alternative Disposal: Involves sampling the drill cuttings to be sent for laboratory analysis before coordinating equipment to haul the waste to landfill under applicable governmental criteria. Landfill applications will be completed by Wellsite Environmental Inc. .
Facility Disposal: Utilizing waste management facilities for disposal of drilling waste. At times it will be more time efficient and/or economical to utilize such facilities as opposed to more traditional methods such as Landspread on Pipeline Right of Way or Landspray. The client is responsible to track the wastes that go to these facilities and Wellsite Environmental Inc. can supervise the disposal as well as track the wastes and to summarize in drilling waste summary reports.
Reporting and Governmental Submission: At completion of the drilling operations Wellsite Environmental Inc. will report on all works performed as well as summarize all drilling waste and disposal. Depending on the client’s specific request Wellsite Environmental Inc. can perform relevant governmental submissions.
