Steam Injection Well Control Incident Update #2

May 8, 2024 | Announcement

Stakeholder Update from Harvest Operations Corp.
May 8, 2024

Dear Community Members,

As we enter our second weekly update on the emergency response efforts, Harvest is pleased to report that progress continues to be made, thanks to the collaborative efforts of our dedicated teams and the invaluable support from our local communities. Over the past week, we have had the privilege of hosting stakeholders on site tours, providing a firsthand look at the impacted lands and our ongoing operations. The feedback we’ve received has been overwhelmingly positive, affirming our shared commitment to addressing the challenges at hand.

It has been heartening to witness the engagement and interest from members of the community, and we are deeply grateful for your continued involvement. Notably, we have observed the significant contribution of contractors from within the communities, underscoring the importance of local expertise and collaboration in our cleanup endeavors. As we move forward, we remain steadfast in our dedication to working closely with all stakeholders to ensure a thorough and effective response to this emergency.

The stakeholder meeting did provide details on the estimated volume of the release. Based on the area of impact, duration of the release, projected composite of the emulsions, the volume of the release is estimated to be 650m3 of emulsion (75% water 25% oil), and 405m of steam. We will continue to revisit this estimate as we remedy the impacted soil and vegetation.

Site Clean-up Activities
  • Clearing/mulching of heavily impacted vegetation areas around the lease is continuing.
  • Further to the original temporary workspace granted last week, Harvest will need to expand this request to accommodate further clearing of heavily impacted trees.
  • Surface cleaning of lease and surrounding areas is continuing in prioritized work areas. The free product is being collected on lease in a burned area and will be stabilized with tree mulch and hauled to disposal starting Friday.
  • Cleaning of third-party equipment and on-site infrastructure continues in prioritized order.
  • Free-standing water and fluids on the lease and surrounding areas have been removed and will be maintained as required.
Wildlife Management
  • Woodland Caribou is of particular concern at this time of year, the presence of oil-covered trees poses imminent threat to the calving habitat of Woodland Caribou.
  • 24 hour hazing of the spill area and additional hazing is provided during day shift along the outer extents of the release area by two crews with argos. This has so far been successful for deterring the Caribou.
  • Additionally, four bird species with provincial and federal sensitivity listings, including Sora, American Kestrel, Black Tern, and Olivesided Flycatcher have been identified in the release area.
  • Retention ponds have been drained to prevent any birds from accessing contaminated water.
  • Wildlife sweeps are ongoing, yesterday we had identified one Canadian Toad.
Vegetation Impact
  • Harvest is working closely with the AER to assess the footprint of the impacted vegetation. We are sampling and assessing based on three grades of impact; lightly misted, moderately misted, and severely misted areas.
    • Lightly misted area is affecting approximately 1,363,893 m2.
    • Moderately misted area is affecting approximately 296,396 m2.
    • Severely misted area is affecting approximately 351,197 m2.
  • A severely misted area was identified near the well pad. The misting lessened the further away from the lease however open cut lines where canopy cover is not present has resulted in oiled ground cover. The severely misted oil-covered trees are being removed promptly to prevent nesting by birds and calving by Woodland Caribou in the affected area. Heavily impacted trees must be removed with tree felling crews, while preserving as much unimpacted forest floor vegetation as possible.
  • Light misting was identified on vegetation up to the extents of the identified release area. In some of the lightly misted areas, canopy cover is not present resulting in oiled ground cover. Lichens, willows, mosses, grasses and sedges provide a food source for ungulates, particularly Caribou. Any vegetation removal will be conducted using hand tools to mitigate further disturbance.
Watercourse Impact
  • Due to current conditions the wetland complex is very dry, the areas sampled are the only locations where water or ice was present for sampling activities along the unnamed ephemeral watercourse.

We are committed to addressing this incident responsibly and minimizing its impact on the environment and wildlife. Your safety and well-being of the ecosystem are our top priorities.

If you have any questions or concerns, please don’t hesitate to reach out. I can be contacted at 403-268-6597 or carmen.brown@harvestenergy.ca
