Why Choose Terminis?
Terminis delivers a complete suite of abandonment, coiled tubing, and vent flow repair services designed for precision, safety, and cost efficiency. Our engineering-driven approach ensures every project meets regulatory standards while reducing downtime and overall spend.
Our clients span the energy ecosystem across Alberta, Saskatchewan, and British Columbia.
We provide abandonment and SCVF services for:
Founded in 2015, Terminis was built on the belief that well abandonments should be approached with engineering discipline, operational control, and execution excellence. We saw the inefficiencies caused by third-party equipment rentals and inconsistent contractors — so we invested in owning our fleet and building a team of specialists.
Terminis specializes in downhole abandonments and Surface Casing Vent Flow (SCVF) repairs for the oil and gas industry. With engineering expertise, skilled field teams, and an owned fleet of equipment, we deliver reliable, end-to-end abandonment solutions.
Our coil-based methods reduce costs by up to 30%, minimize downtime, and ensure full compliance with AER and regulatory standards—helping operators eliminate unnecessary costs, delays, and risks.
A downhole abandonment is the process of permanently sealing an inactive or end-of-life oil or gas well. This work prevents leaks, protects groundwater sources, and ensures compliance with regulatory requirements such as those from the Alberta Energy Regulator (AER).
At Terminis, we engineer and execute abandonments using methods like cement plugs, casing cuts, and section milling to fully isolate the wellbore. Proper abandonment reduces long-term liability for operators and landowners while meeting strict environmental standards.
Coiled tubing technology is a safer, faster, and more cost-efficient way to complete well abandonments. Compared to traditional rig-based methods, coiled tubing allows for:
Precise plug placement at targeted depths
Reduced rig time and surface footprint
Lower costs by up to 30% due to efficiency gains
Less disruption for landowners and surface sites
At Terminis, our fleet of coiled tubing units is owned and operated in-house, giving clients greater reliability and cost control.
A Surface Casing Vent Flow (SCVF) happens when gas migrates between well casings and escapes at the surface through the vent. This can lead to:
Environmental risks, including methane emissions and groundwater contamination
Regulatory non-compliance, which can result in fines or operational delays
Increased liability for operators and asset owners
Terminis Downhole Services specializes in SCVF diagnosis and repair, using engineered solutions that eliminate leaks and restore compliance quickly.
Many service providers rent or subcontract equipment, which can create higher costs, delays, and less control. Terminis owns and operates our own:
Coiled tubing units
Pressure trucks
Section milling tools
Support equipment
This ownership ensures better scheduling, lower downtime, cost efficiency, and consistent quality control — giving our clients confidence that projects will be completed on time and on budget.
We serve oil and gas operators across Alberta, Saskatchewan, and Western Canada, with a strong presence in Calgary and surrounding regions. Whether you’re managing a single well or a large-scale abandonment program, Terminis provides the engineering, equipment, and execution needed to complete the work safely, efficiently, and in full regulatory compliance.
From E&P companies to portfolio owners, our clients choose Terminis for precise well abandonments,
SCVF repair, and program management—on time, in budget, and in full regulatory compliance.
