Real Results

ELM Inc. will leverage performance metrics and clear accountability to drive “real results” that create value for our employees, customers, and stakeholders that will result in ELM setting the industry standard for Environmental Liability Management.

ELM has abandoned more than 2,700 wells and approximately 1,360 pipelines.

  • Re-Entry for repairs on over 50 wells
  • Over 300 , vent flows and gas migration repairs

ELM has decommissioned more than 700 well sites, and more than 60 facilities.

ELM has completed over 27 line splits and reactivations.

ELM has performed over 12 pipeline repairs and optimizations.

ELM has completed over 84 projects in various reclamation and remediation capacity driving sound land management practices, driving conservation solutions and returning to equivalent land capability.

ELM has completed a numerous of various assessments for various industries. More than 8,000 wellbores were assessed to support clients decisions around budgets and corporate planning for acquisition and divestiture.
Over 415 reports and assessments were carried out delivering liability management and impact solutions in support of client corporate planning and environmental stewardship.

  • Reduction in the H2S in produced water
  • Re-usage of drilling water at frac/drill sites or at treatment facilities
  • Reduction water handling cost
  • Reduction in well work-over cost
  • Increased environmental stewardship
  • Increased in operational efficiencies
  • Enhanced oil recovery
  • Enhancing safety by reducing trucks on the road; no free fluid transported and/or high-risk chemicals
  • Allowing client to control water from source to reuse/disposal (self-reliant)

Actual Case Studies

The following is a summary of the highlights taken from client engagements:

The following is a summary of the highlights taken from a client engagement:

Client Environment

Customer had an internal budget of $1.5M for Inactive Well Compliance Program ("WCP") wells. The customer was having to communicate across 4 internal reporting departments and was dealing with multiple service providers costing him time and money. There was the need for a well file review but the customer was being challenged with constant scope changes and a lack of innovation not to mention the absence of a firm “game plan” for moving forward.

ELM’s Solution

A complete well file review was performed, and wells were prioritized. ELM then developed a preliminary cost estimate based on designing a program which in turn was based on an analysis of ARO and LLR. Operational efficiencies were reviewed and a risk and cost mitigation plan were developed. A set of performance metrics were identified prior to the start of the program to ensure successful execution.

Program Deliverables

The client was given cost assurance through ELM’s exclusive "Cost Cap" overrun protection solution. ELM became the single source service provider for all aspects of the abandonment and decommissioning programs resulting in resource optimization, better communication, innovative solutions, as well as a both program were delivered on time, on budget, and within scope. The client also came away with a full understanding of measurable impacts of financial, environmental, and regulatory liabilities.

“BOTTOMLINE” = direct program savings in excess of 25%.

Case #1 (Brownfield Site Reclamation)

Client Environment

The client wanted to reclaim roughly 1000+ metres of shoreline along the St Lawrence River in Ontario. The site was associated with a closed dairy and was previously used to stock pile coal.


ELM Solution

A focal soil excavation strategy focusing on coal, ash and hydrocarbon-stained soil was developed using field information collected through field samples of soil, groundwater, and evaluation of plant life.

Program Deliverables

Contaminated soil was excavated and replaced with clean fill. Non-native plants were removed and a park was created on the site using placement of rocks along the shoreline along with native plants. Results permitted the focal excavation of contaminted soils and buried debris. We were also able to improve drainage to the river where Species at Risk were evident, but not part of the original study.

Bottom Line

The project was completed 6 months earlier than expected due to the strategy used by ELM saving the client $100,000.



Case #2 (Remote Oil Well Abandonment along Lake Huron)

Client Environment

ELM was contracted to help the client locate ‘lost’ oil wells from the 1800s era within the shoreline of Lake Huron in Ontario. The work had to be performed in close proximity to the sensitive lake shoreline where woodlands were known to be used by Species at Risk.


ELM Solution

Once the oil wells were located, abandonment involved separating the soil into stock piles based on colour, odour, as well as proximity to the oil wells. Focal soil sample analyses were used to determine extent of excavation and remediation.

Program Deliverables

ELM as able to return 70% of the soil back to the excavation site with the remainder sent to a secure landfill. Imported top soil was brought in and mixed with local soils to improve reclamation efforts. ELM was also able to improve drainage to Lake Huron.

Bottom Line

The client was able to save well over $100,000 in landfill fees because of ELM’s soil stock piling strategy. In addition, the client was able to save more than $50,000 in fees for the delivery of clean fill to the remote site as a result of reusing clean soil secured at site.



Case #3 (Government Facility)

Client Environment

The client engaged the services of ELM to come in and clean up a creek and pond habitat that was marked as no longer capable of supporting fish or other aquatic life.


ELM Solution

ELM established an innovative new protocol to separate asbestos that was in the soil and reduced the total amount of soil being sent to the landfill. We conducted a study that revealed new Species at Risk on the site and determined habitat improvement and measures to benefit these Species at Risk.

Program Deliverables

ELM carefully completed soil removals to achieve retention of a large number of mature trees across the site. We also planted species of trees that were native to the area but hadn’t been seen in the area since the 1800s.

Bottom Line

ELM was able to save the client more than $250,000 in project costs as a result of the innovative protocol we established.
