DRILLING WASTE MANAGEMENT

Complete Solutions

Drilling waste management is ever evolving as new drilling fluid systems get developed, and regulatory guidelines change over time.

By working closely with your environmental services company during the planning stages of your drilling fluids program, we can help you identify potential disposal issues that could result in increased costs, and we can offer you suggestions that can help you meet your fluid performance objectives while helping your company develop the most cost efficient disposal program.

The drilling fluids system that you select will directly affect the options that you have for disposing of the drilling waste generated from all sections of your well.

Drilling Waste Disposal Planning

 

Having a thorough drilling waste management plan is essential for communicating drilling waste disposal options to all parties involved in drilling operations. When properly developed and executed, a drilling waste management plan will save you time and money.

Our comprehensive drilling waste management plans include:

  • Determination of disposal options for the selected drilling fluid system to comply with regulatory guidelines for the province of operation.
  • Conduct sump suitability assessments and above ground earthen bermed storage areas assessments when required.
  • Preparation of a detailed step by step plan for managing each unique drilling waste component (fluids, solids, and cement).
  • Preparation and submission of written notifications to appropriate regulatory bodies before disposal of drilling waste.
  • Preparation and submission of drilling waste management facility waste disposal applications.
  • Contingency planning if weather conditions or drilling conditions dictate a deviation from the original drilling waste management plan.
  • If requested, arrange services including vacuum trucks, storage tanks, mixing and storage bins, sawdust delivery, and trucking services for waste transport to an approved waste management facility.

 

Disposal Options

 

Currently, the most common disposal options for drilling waste are:

  • Landspray While Drilling (LWD) – A cost effective solution for the disposal of water-based drilling waste that eliminates the associated costs of selecting and constructing drilling sumps. Disposal of drilling waste typically occurs on agricultural lands. In May of 2012, the Alberta Energy Regulator released the Directive 50: Drilling Waste Management (2012) disposal guide. New criteria for drilling sump construction were included that could result in much higher costs for the acquisition of suitable land and construction of sumps.
  • Disposal Onto Forested Public Lands (DFPL) – Disposal of drilling wastes similarly to LWD, however, the disposal usually occurs in winter on specific types of dispositions issued under the Alberta Public Lands Act.
  • Mix Bury and Cover (MBC)/Residual Solids Disposal (RSD) – A method of disposal where by drilling waste is mixed with receiving soil to create a consistent mass of material that is then covered by clean fill to complete the disposal. Most often used to manage segregated drill cuttings or in conjunction with a pump off disposal option.
  • Landspread On Lease (LOL) – Method used to dispose of water based drilling waste by spreading out on the surface of a wellsite, pipeline right of way or a remote site and then incorporating the waste into the shallow subsoil on location.
  • Pump Off – Disposal of the clear fluid portion of drilling waste onto typically vegetated land. Often used in conjunction with another option for the disposal of drilling waste solids such as mix, bury, and cover. Pump Off Disposal is a cost effective way to reduce the volume of waste before mixing off the remaining sump liquids and solids.
  • Approved Waste Management Facility – There are times when the only feasible solution to dealing with drilling waste is to use a drilling waste management facility. We provide comprehensive waste characterization, analytical data review, acquisition of waste management facility approvals and tracking of wastes on your behalf to ensure fast turnaround times and cost effective disposal solutions.

Drilling Waste Tracking & Manifesting

 

Combined with an appropriate drilling waste management plan, tracking of drilling wastes generated from drilling projects is key in ensuring that waste streams are segregated, and the location of wastes is known at all times. Improper tracking or integration of incompatible drilling wastes can result in thousands of dollars in additional disposal and clean-up costs.

Keneco Environmental Offers:

Field supervision of drilling waste disposal activities and ongoing inspection of drilling waste containment areas to ensure no cross contamination of drilling wastes has occurred.
