An oil or natural gas well can stop producing long before the equipment surrounding it disappears from the landscape.
When production ends, the operator must determine whether the well will remain suspended for possible future use or be permanently abandoned.
Permanent abandonment requires specialized work deep underground. Producing formations must be isolated, potential leakage pathways addressed and suitable barriers installed to protect groundwater and surrounding geological formations.
Only after the necessary downhole work and testing have been completed can the remaining wellhead be removed and the surface abandonment finished.
This work creates demand for a specialized group of Alberta oilfield service companies.
Some businesses manage entire abandonment programs involving hundreds of wells. Others operate coiled tubing units, service rigs, cement pumping equipment, wireline tools and specialized wellhead cutting systems.
Environmental consulting companies also play an important role by evaluating well integrity, investigating gas migration and coordinating site remediation and reclamation.
Alberta’s well abandonment industry includes companies such as ELM, Terminis Downhole Services, CG Engineering, ProFoxx Asset Retirement Management, Stingray Well Solutions and Performance Energy Services.
Other businesses, including Clear Choice Energy Services, ProJet Energy Services and ACE Energy Services, specialize in the final wellhead cutting and capping operations.
This guide profiles 18 companies involved in well abandonment in Alberta, explains their different services and examines the equipment and regulatory requirements involved in permanently closing oil and natural gas wells.
The companies are grouped by what they actually do rather than ranked by size.
Some manage complete abandonment projects, while others provide one specialized part of the operation. These distinctions matter when selecting contractors.
What Is Oil and Gas Well Abandonment?
Well abandonment is the process of permanently taking an oil or natural gas well out of service.
In Alberta, abandonment is regulated by the Alberta Energy Regulator, commonly called the AER.
The principal technical requirements are established in Directive 020: Well Abandonment.
The directive sets out requirements for isolating producing formations, protecting groundwater, testing well integrity and completing surface abandonment.
The AER issued an updated version of Directive 020 on July 27, 2026.
This edition includes changes relating to notifications, certain routine abandonment applications and procedures for reentering previously abandoned wells.
An abandonment program must be designed according to the well’s actual construction and operating history.
A shallow conventional gas well may require a relatively straightforward abandonment.
A deep horizontal well with damaged casing, unwanted gas migration or complicated completion equipment may require substantial intervention work.
The objective is to establish appropriate barriers that prevent unwanted fluid movement between underground formations and toward the surface.
An abandoned well is not necessarily a reclaimed site.
Abandonment addresses the well itself. Remediation addresses contamination where it exists, while reclamation involves restoring the disturbed land to an appropriate condition.
These are different stages of the oilfield closure process.
Companies Managing Complete Well Abandonment Programs in Alberta
A complete well abandonment program can involve engineering, regulatory submissions, field supervision, equipment coordination, cementing and final reporting.
Some Alberta companies specialize in managing these activities for oil and natural gas producers.
They may hire separate cementing, service rig and cutting contractors to perform the physical work.
1. ELM Inc.
ELM Inc. is a Calgary headquartered company specializing in environmental liability management and oilfield closure.
The business provides well abandonment, facility decommissioning, remediation and reclamation services.
Well abandonment is one of ELM’s principal areas of expertise.
The company manages projects involving the permanent closure of oil and natural gas wells, including technically challenging operations.
Complete Well Abandonment Management
ELM provides abandonment planning, well assessments, cost estimating and project execution.
Its services include evaluating existing wellbore conditions and determining what work is required before permanent closure.
Older wells may have incomplete records, damaged casing or previous cementing problems.
These conditions must be considered when developing an abandonment program.
ELM also coordinates downhole abandonment operations.
This can involve removing tubing, preparing the wellbore, installing isolation barriers and performing required testing.
The company provides wellhead cutting and capping as part of broader closure programs.
It also manages regulatory reporting and communication with landowners and other stakeholders.

This makes it suitable for producers seeking one organization to coordinate several stages of their closure responsibilities.
ELM is primarily a project management and environmental liability specialist rather than a conventional service rig contractor.
It coordinates the necessary technical contractors according to the requirements of each site.
2. Terminis Downhole Services
Terminis Downhole Services is a Calgary based company specializing in oil and natural gas well abandonment.
The company was founded in 2015 and operates throughout Western Canada.
Terminis differs from some abandonment consulting businesses because it owns and operates specialized field equipment.
Its fleet includes coiled tubing units, pressure trucks, hot oil equipment and section milling tools.
Coiled Tubing Well Abandonments
Coiled tubing can be used during selected abandonment operations to access the wellbore and perform downhole work.
The equipment runs continuous steel tubing from a reel.
Fluids can be circulated through the tubing, and specialized tools can be deployed at the end of the string.
Terminis uses coiled tubing for operations associated with wellbore isolation and abandonment.
The company also provides pressure pumping equipment to support these activities.
Owning both equipment types allows Terminis to coordinate certain operations without relying on separate contractors for every component.
Section Milling
Section milling involves removing a selected interval of casing using specialized downhole tools.
The operation may be considered where existing casing and cement conditions make conventional isolation difficult.
After the necessary wellbore preparation, an appropriate barrier can be installed according to the abandonment program.
Section milling is technically demanding because the tools must operate inside the well while removing steel and managing debris.
Terminis owns section milling equipment as part of its abandonment business.
Surface Casing Vent Flow Repairs
Terminis also specializes in repairing surface casing vent flow problems.
These repairs can involve identifying leakage pathways and performing downhole isolation work.
The company provides engineering, field execution and project management.
Its services are particularly relevant to producers seeking specialized abandonment methods for wells that may not require a conventional service rig throughout the entire operation.
However, whether coiled tubing is appropriate must be determined from the well design and abandonment requirements.

Well Integrity Testing
Aurora performs surface casing vent flow and gas migration testing.
These tests help identify unwanted gas movement associated with an oil or natural gas well.
The results can influence the abandonment program.
A well with a significant integrity problem may require corrective work before final closure.
Aurora also provides packer isolation testing and other technical assessments.
Site Assessment and Abandonment Preparation
Aurora performs preliminary site inspections.
These assessments can document wellhead conditions, equipment inventories, site access and possible environmental concerns.
Collecting this information before mobilizing a service rig or cementing contractor can help identify potential problems.
The company also develops reclamation cost estimates and environmental assessments.
Reclamation and Environmental Closure
Aurora manages remediation and reclamation projects after abandonment.
This may involve evaluating soil and groundwater conditions, directing cleanup work and preparing documentation for reclamation certification.
Aurora does not primarily operate conventional cement pumping or service rig fleets.
Its role is environmental consulting, well integrity evaluation and closure program support.
Wellhead Cut and Cap Companies in Alberta
Once the appropriate downhole barriers have been installed and the necessary testing completed, the surface abandonment can proceed.
This commonly involves removing the upper portion of the well casing below ground level and installing the required cap.
Cut and cap work is a specialized service.
It requires equipment capable of cutting casing and removing the remaining wellhead components.
The following companies focus on this stage of the abandonment process.
10. Clear Choice Energy Services

Clear Choice uses several methods for cutting well casing.
Internal Hydraulic Cutting
The company’s internal hydraulic cutting system operates inside the casing.
The cutting equipment is lowered into the casing to the required depth.
A hydraulic cutting mechanism then separates the casing.
This approach can reduce the need for extensive excavation in suitable applications.
It can be particularly useful where access is restricted or surface disturbance needs to be minimized.
Abrasive Water Jet Cutting
Clear Choice also provides abrasive water jet cutting.
The process uses high pressure water and abrasive material to cut steel.
This method can be used for larger casing configurations and selected thermal well applications.
The suitability of the method depends on the well construction and site conditions.
Conventional Excavation and Cutting
Not every well is suitable for internal cutting.
Some sites require excavation to expose the casing.
Clear Choice also performs conventional wellhead cutting and capping.
Its crews work throughout Alberta, including Central Alberta, Grande Prairie, the Peace region and southeastern Alberta.
The company is a specialized cut and cap contractor rather than a provider of complete downhole cementing operations.
11. ProJet Energy Services

Its abandonment offering is marketed as Turbo Cut and Cap.
Turbo Cut and Cap
ACE uses high pressure water cutting technology to separate casing during well abandonment operations.
The system is designed for controlled casing cutting without relying on conventional thermal cutting methods.
This can be useful where the operator wants to minimize heat generation during cutting.
The equipment is used after the necessary downhole work and testing have been completed.
Casing and Tubular Services
ACE also provides casing running equipment, power tongs and related tubular handling services.
These are normally associated with well construction and other operations involving casing or tubing.
The company’s experience with tubular equipment complements its cutting and capping business.
ACE provides equipment rentals and associated field support.
Its role in abandonment is primarily specialized casing cutting and surface equipment work.
It should not automatically be treated as an engineering company responsible for designing and executing every downhole barrier required for permanent well abandonment.
Cementing Companies Supporting Well Abandonment in Alberta
Cement is one of the most important materials used to establish permanent wellbore barriers.
During abandonment, cement may be placed inside the casing, across selected formations or into intervals where existing isolation needs to be repaired.
This work requires specialized pumping equipment and cement slurry formulations.
Alberta has several contractors specializing in remedial and abandonment cementing.
13. Stingray Well Solutions
Stingray Well Solutions is an Alberta oilfield company specializing in remedial and abandonment cementing.

Its services include specialized cement blends for remedial applications.
Some wells may require microfine cement, alternative slurry systems or other products designed for difficult placement conditions.
Magnum uses laboratory testing to help develop appropriate formulations.
Downhole Isolation Tools
One of Magnum’s distinguishing capabilities is its combination of cementing with downhole isolation tools.
The company supplies tools used during plugging and abandonment operations.
These can include equipment that helps establish mechanical barriers or control cement placement.
Combining cementing and downhole tools can simplify coordination during selected jobs.
For example, a remedial operation may require a mechanical retainer to be installed before cement can be placed into the intended interval.
Magnum can provide technical support and equipment associated with both parts of the operation.
More Than Cementing
Magnum also operates fluid services and industrial support divisions.
Its expanded corporate branding reflects this broader business.
However, its relevance to well abandonment comes primarily from remedial cementing and downhole isolation technology.
Service Rig Companies Performing Well Abandonment
Some abandonment programs require tubing, rods or other downhole equipment to be removed before the permanent barriers can be installed.
A conventional service rig may be used for this work.
Service rig contractors generally provide lifting and tubular handling equipment rather than designing the entire abandonment program.
18. Precision Well Servicing
Precision Well Servicing is the Canadian well servicing business of Calgary headquartered Precision Drilling Corporation.
The company operates a substantial fleet of service rigs throughout Western Canada.
Its services include completions, workovers, well maintenance, abandonment and reentry preparation.
Removing Downhole Equipment
Before a well can be permanently abandoned, the existing completion may need to be removed.
This can include production tubing, sucker rods, packers and other equipment.
Precision’s service rigs provide the lifting and tubular handling equipment needed for these operations.
Different rig configurations are available according to the well depth and equipment requirements.
Abandonment and Reentry Preparation
Precision also provides service rigs for selected reentry operations.
Some previously abandoned wells may require reentry because an integrity problem has been identified.
Other projects involve preparing existing wells for corrective work.
The appropriate operations depend on regulatory requirements and the condition of the well.
Current Ownership of Former Service Rig Fleets
Precision expanded its well servicing business through major acquisitions.
It acquired High Arctic’s Canadian well servicing operations in 2022.
Precision also completed its acquisition of CWC Energy Services in 2023.
These acquired service rig assets became part of Precision’s broader operations.
Older listings identifying the former High Arctic or CWC well servicing fleets as separate independent contractors may not reflect current ownership.
Precision remains an important provider of the service rig equipment used during Alberta abandonment programs.
What About the Orphan Well Association?
The Orphan Well Association is an important part of Alberta’s oil and gas closure system.
However, it is not a conventional oilfield service company competing for private well abandonment contracts.
The association manages wells and other petroleum infrastructure that have been designated as orphaned because no legally or financially responsible party remains available to carry out the required work.
The Orphan Well Association coordinates abandonment, decommissioning, remediation and reclamation.
It hires qualified contractors to perform the required services.
Those contractors can include engineering firms, cementing companies, service rig operators, environmental consultants and specialized cutting businesses.
The association is funded principally through an industry levy administered under Alberta’s regulatory framework.
An orphan well is different from a well that is simply inactive.
A producing company can have inactive wells that remain its responsibility.
Those wells do not automatically become orphaned.
The Orphan Well Association becomes involved according to the applicable designation and regulatory processes.
For contractors, Orphan Well Association procurement opportunities represent one part of Alberta’s broader site closure market.
How Is an Oil or Gas Well Abandoned in Alberta?
The specific abandonment procedure depends on the well.
However, most projects involve several stages of preparation and field work.
Well File Review and Planning
The operator begins by reviewing the well’s history.
Important information includes casing sizes, cement records, producing intervals, well depth, pressure conditions and previous workovers.
The purpose is to determine whether the existing well barriers are adequate and what additional work is required.
A well abandoned under an incorrect assumption about its construction can create serious problems.
That is why engineering review is important.
Well Integrity Testing
The well may require testing before abandonment.
This can involve pressure tests, surface casing vent flow testing, gas migration surveys and other evaluations.
The results help determine whether repairs are required.
Companies such as ELM, CG Engineering, Subterra and Aurora provide related technical assessment and management services.
Removing Completion Equipment
The existing production equipment may need to be retrieved.
This can include tubing, rods, pumps and other downhole components.
A service rig or specialized intervention unit may be required.
Some jobs also involve fishing tools to recover damaged or stuck equipment.
Preparing the Wellbore
The wellbore must be prepared for proper isolation.
This may involve circulating fluids, cleaning the wellbore or performing remedial work.
The objective is to create suitable conditions for installing the required barriers.
Not every well requires identical preparation.
Installing Isolation Barriers
Cement and, where permitted and appropriate, mechanical equipment are used to isolate selected intervals.
The abandonment program must account for producing formations and protected groundwater.
Cement placement can involve different methods depending on the well conditions.
Sanjel, Magnum, Stingray, Performance and Charger are examples of Alberta companies providing remedial cementing services.
Repairing Integrity Problems
Some wells have problems that must be addressed before final abandonment.
These can include casing leaks, gas migration and inadequate cement isolation.
Corrective work may involve squeeze cementing, special downhole tools or more complicated intervention methods.
Terminis and other specialized contractors can provide equipment for selected difficult wellbore operations.
Surface Abandonment
Once the required subsurface work has been completed, the wellhead can be removed and the casing cut and capped according to the applicable requirements.
The AER generally requires casing to be cut at least one metre below ground level, subject to specified exceptions and requirements.
The casing is then capped using an appropriate vented arrangement.
Companies such as Clear Choice, ProJet and ACE specialize in this type of work.
Site Remediation and Reclamation
After abandonment, remaining surface equipment is removed and the site must be addressed according to applicable environmental and reclamation requirements.
If contamination exists, remediation may be necessary.
Reclamation involves restoring the land to an appropriate condition.
The operator remains responsible for these obligations even after the well has been permanently abandoned.
Well Abandonment Versus Well Suspension
These terms are sometimes used interchangeably, but they describe different stages.
A suspended well has been taken out of production while maintaining the possibility of future use.
The operator must meet the applicable suspension requirements and continue managing the well.
An abandoned well has been permanently taken out of service.
Appropriate barriers are installed to isolate underground formations and protect groundwater.
Suspension does not eliminate the future abandonment obligation.
A well may remain suspended for an extended period before the operator determines that it should be abandoned.
The Alberta Energy Regulator has separate technical requirements for suspension and abandonment.
For producers managing numerous inactive wells, understanding these differences is essential when planning closure expenditures.
What Is Surface Casing Vent Flow?
Surface casing vent flow, often abbreviated SCVF, occurs when gas or fluid moves through the surface casing vent system.
The condition can arise for different reasons.
In some cases, unwanted fluid movement may be associated with problems involving cement isolation or other aspects of well integrity.
A vent flow does not automatically mean that a well is leaking directly into groundwater.
However, the condition must be evaluated and managed according to the applicable requirements.
Testing may involve measuring pressure, flow and gas composition.
If corrective work is necessary, the operator must develop a suitable repair program.
This can involve remedial cementing or other specialized intervention methods.
Several Alberta abandonment companies specialize in these investigations because unresolved vent flow can complicate permanent well closure.
How Gas Migration Affects Well Abandonment
Gas migration refers to unwanted movement of gas through subsurface pathways.
These pathways can sometimes be associated with the area surrounding a wellbore.
Gas migration testing is an important part of assessing potential leakage concerns.
Specialized contractors may use soil gas measurements, pressure testing and other methods to investigate the condition.
If gas migration is identified, the operator must determine whether corrective work is required before the well can be permanently closed.
A successful abandonment depends on establishing appropriate isolation rather than simply removing the surface wellhead.
This is why well integrity engineering and remedial cementing are important parts of Alberta’s closure industry.
Alberta’s Well Abandonment Requirements in 2026
The Alberta Energy Regulator establishes the requirements for oil and gas well abandonment.
Directive 020 is the principal technical directive.
Its July 2026 update introduced several procedural changes.
The regulator clarified notification requirements for different abandonment operations, including zonal abandonment, surface abandonment and certain reentry work.
It also modified requirements associated with some routine operations and specified geological conditions.
However, the technical objective remains the same.
The operator must establish appropriate isolation of the relevant formations and protected groundwater.
The required program depends on the well.
Some routine operations can proceed under established requirements.
Others may need additional regulatory approval.
Companies planning abandonment work should use the current directive rather than relying on older versions.
Why Well Abandonment Work Continues Across Alberta
Well closure is an ongoing part of the petroleum industry.
Some wells are abandoned because they are no longer economically productive.
Others are abandoned because of mechanical problems or changes in development plans.
Still others are part of larger site decommissioning programs.
Alberta’s regulatory framework also requires companies to address inactive infrastructure.
Alberta’s Annual Closure Quota
The Alberta Energy Regulator has established an industry closure spending quota for 2027 of $750 million.
The quota is allocated among applicable operators according to the regulator’s liability management framework.
It covers eligible closure work, which can include decommissioning, remediation and reclamation.
The amount should not be interpreted as money reserved exclusively for downhole well abandonment contractors.
Different companies will spend their required amounts on different types of closure work depending on their assets and obligations.
For service companies, this framework supports continuing demand for specialized closure services.
However, the level of work received by individual contractors depends on customer budgets, procurement decisions and the specific projects being completed.
Well Abandonment Companies by Alberta Region
Abandonment projects occur throughout Alberta.
Contractors frequently mobilize across the province rather than operating only near their head office.

How to Choose a Well Abandonment Company in Alberta
The appropriate contractor depends on the well and the services required.
A producer planning a large closure program may need an engineering and project management company.
A well requiring only remedial cementing may need a specialized pumping contractor.
A well that has already completed downhole abandonment may only require final cut and cap work.
Determine the Scope of Work
The first step is identifying which stage of closure must be completed.
Possible requirements include well integrity testing, tubing removal, cementing, mechanical isolation, surface abandonment or environmental reclamation.
The contractor should have experience with the specific work.
Review the Well’s History
Older wells can contain complicated completion equipment or previous repairs.
The abandonment company should review available records before selecting the equipment and procedures.
Wells with uncertain casing or cement conditions may require additional evaluation.
Confirm Technical Capabilities
A company specializing in cut and cap is not necessarily equipped to perform downhole cementing.
A cementing contractor may not provide service rigs.
An engineering consultant may coordinate the operation without owning the necessary field equipment.
The operator should understand which services will be performed directly and which will be subcontracted.
Evaluate Gas Migration and Vent Flow
If a well has known integrity problems, the selected contractor should have suitable experience investigating and addressing them.
These conditions can materially change the abandonment program.
They should be evaluated before final surface abandonment is scheduled.
Consider Equipment Availability
A project may require a service rig, cementing unit, wireline contractor and cutting crew.
Scheduling all these services can be complicated.
For multiple well programs, coordinating equipment across nearby locations can improve efficiency.
Review Regulatory Experience
The contractor should understand current Alberta Energy Regulator requirements.
This includes appropriate notifications, technical procedures and reporting.
Some nonroutine operations require additional regulatory approval.
Consider Surface Access
Remote wells can be difficult to access.
Some may require winter roads or specialized transportation.
Other wells are located on agricultural land where the timing of operations can affect the landowner.
Access should be considered early in planning.
Understand Total Closure Costs
A well abandonment quotation may cover only part of the work.
The total cost can include engineering, testing, well servicing, cementing, wireline, surface cutting and final reporting.
Environmental remediation and reclamation may create additional costs.
A producer should compare quotations based on the complete scope rather than a single equipment rate.

Yes.
Coiled tubing can be used for certain abandonment operations.
Terminis is an example of a company specializing in coiled tubing based abandonment methods.
However, not every well is suitable for the same equipment.
What Is the Difference Between Well Abandonment and Reclamation?
Well abandonment involves permanently isolating and closing the wellbore.
Reclamation involves restoring the surface land to an appropriate condition.
Remediation may also be necessary if contamination is present.
The activities have different technical and regulatory requirements.
Who Is Responsible for Abandoning an Oil or Gas Well?
The responsible licensee must meet the applicable abandonment and closure obligations.
Hiring a contractor does not automatically transfer those regulatory responsibilities.
Does the Orphan Well Association Hire Abandonment Contractors?
Yes.
The Orphan Well Association uses qualified contractors to perform abandonment, decommissioning and other closure work.
It manages orphaned infrastructure through a separate process from the normal closure obligations of operating producers.
What Is Surface Casing Vent Flow?
Surface casing vent flow involves gas or fluid movement through the surface casing vent system.
The condition may require investigation and corrective work.
It is not automatically equivalent to gas migration through surrounding soil.
What Is Squeeze Cementing?
Squeeze cementing involves placing cement into a selected well interval under controlled pumping conditions.
It is used for certain well repairs and isolation operations.
The appropriate treatment depends on the wellbore and the intended barrier.
How Long Does Well Abandonment Take?
The time required depends on the well.
Some relatively straightforward operations can be completed quickly.
Other wells require multiple visits, testing, equipment recovery or complex remedial work.
Regulatory requirements and site access can also affect the schedule.
Can an Abandoned Well Ever Leak?
Yes.
Although well abandonment is designed to establish permanent isolation, integrity problems can sometimes occur later.
The responsible company must address problems according to the applicable regulatory requirements.
Are There Well Abandonment Jobs in Alberta?
Yes.
Abandonment projects require wellsite supervisors, engineers, cementing operators, service rig crews, wireline personnel, equipment operators, environmental technicians and reclamation specialists.
Work locations vary throughout the province.
Hiring depends on current projects and contractor schedules.
Well Abandonment Is a Specialized Part of Alberta’s Oilfield Industry
The end of oil or natural gas production does not mean the end of work at a wellsite.
In many cases, permanently closing a well requires careful engineering, specialized equipment and several different contractors.
The abandonment program must account for the well’s construction, existing barriers, pressure conditions and geological formations.
Some wells can be closed using relatively conventional equipment.
Others require significant investigation and repair before permanent isolation can be achieved.
Alberta’s service industry has developed a broad range of expertise to perform this work.
ELM, CG Engineering, ProFoxx, Subterra and Tristar provide technical planning and project management.
Terminis combines abandonment engineering with its own coiled tubing and pressure pumping equipment.
Veracity and Sabelli provide field supervision and broader closure project support.
Aurora specializes in environmental assessments, well integrity testing and subsequent site closure activities.
Clear Choice, ProJet and ACE perform specialized wellhead cutting and capping.
Stingray, Performance Energy, Charger, Sanjel and Magnum supply cementing and downhole isolation services.
Precision provides service rigs for tubing removal, workovers and abandonment preparation.
These businesses perform different roles, but all contribute to the process of permanently closing petroleum wells.
Abandonment also supports a separate market for equipment rentals, transportation, environmental testing, excavation, site construction and specialized downhole tools.
The work takes place across nearly every producing region in Alberta.
Grande Prairie and the Peace Country have deep natural gas wells and mature conventional production.
Central Alberta contains extensive conventional oil and natural gas infrastructure.
Whitecourt and Drayton Valley support long established petroleum fields.
Lloydminster and Cold Lake contain conventional and thermal heavy oil operations.
Southern Alberta has numerous mature natural gas wells.
Each region presents different operating conditions.
As Alberta continues addressing inactive petroleum infrastructure, companies specializing in well abandonment will remain important to the province’s oilfield service industry.
For producers choosing contractors, the essential consideration is matching the company to the actual scope of work.
An engineer may be needed to design the abandonment.
A service rig may be required to remove equipment.
A cementing contractor may be needed to establish barriers.
A cut and cap crew may complete the surface abandonment.
Environmental specialists may then manage remediation and reclamation.
Successfully coordinating those activities is essential to closing wells responsibly and meeting Alberta’s regulatory requirements.
