The Orphan Well Association (OWA) is seeking a buyer for a large volume of elemental Sulphur located at the Mazeppa gas plant (Site) near High River, AB. The OWA is interested in receiving expressions of interest from potential buyers, and in exploring proposals to remove the Sulphur off-site.

Site visits can be scheduled & directions can be provided upon request by contacting supplychain@orphanwell.ca.

Please Note: The Site is under full-time security and no access will be granted without prior approval.

AMOUNT OF SULPHUR: Estimated volume of 2,600 m3, with an approximate weight of 5,000 metric tons.

RE: Mazeppa Facility – Cogeneration Power Plant

The OWA and the vested landowner are exploring different options for the Mazeppa Lands as shown below and are currently looking to identify potentially interested parties.

  1. Buyer(s) purchases the unit(s) separately or all of them and relocates the units off the Mazeppa facility. There are 5 (five) x 3.3 Megawatts cogeneration units (16.5MW Total) at the Mazeppa Power Plant Facility located near High River, Alberta.

  2. Buyer purchases entire cogeneration power plant, leaves the units on site and resumes operations.
    Note: The cogeneration power plant is currently not turnkey ready for operations and there are no regulatory approvals in place. Discussions with the vested landowner are also required as part of the process to resume operations. An option for sale of the land by the vested landowner will also be incorporated in the detailed request for proposals that is shared at a later date.

  3. Other –alternate suggestions or solutions for the units may also be reviewed.

For interested parties or for general inquiries about the power generation units, please contact supplychain@orphanwell.ca. The OWA and the vested landowner plan to release a detailed request for proposals in the future with full guidance on requirements and is only looking to identify interested parties at this time.

Please note that the OWA and the vested landowner will not be accepting phone calls for any inquiries relating to this potential sale at this time.

Kind regards,
OWA Team


As part of its investment in the energy industry, the Government of Canada’s plans include a $200 million repayable loan to the OWA. The Government of Alberta has also announced a $100 million repayable loan to the OWA, in addition to a loan announced by the province in 2017 and provided over three years. Service companies interested in working for the OWA can find information in the Work With Us tab.

In addition to loans provided to the OWA, the Government of Alberta also announced the Site Rehabilitation Program, primarily funded by the federal government’s COVID-19 Economic Response Plan, which will provide up to $1 billion in funding to Alberta’s oilfield service contractors to perform well, pipeline, and oil and gas site reclamation work. The Site Rehabilitation Program is a separate program not administered by the OWA. The OWA is ineligible to apply for grant funding. Please go to alberta.ca/siterehab for further information.

The Orphan Well Association is an industry-funded collaboration among the Alberta Government, provincial regulators and oil and gas producers to work toward a common goal: protecting public safety and managing the environmental risks of oil and gas properties that do not have a legally or financially responsible party that can be held accountable. These properties are known as “orphans.” The mandate of the OWA is to safely and efficiently decommission orphan oil and gas wells, pipelines, production facilities and restore the land as close to its original state as possible.
