Defining Best Management Practices for Conservation of Reclamation Materials in the Mineable Oil Sands Region of Alberta
Resource
Task-group formed to define Best Management Practices (BMPs) for conservation of reclamation materials in the mineable oil sands region of Alberta; easier to define BMPs for salvage than replacement
Factors that Result in Sustainable Forest Ecosystem Development on Padded Sites in Peatlands: Pilot Study
Resource
The pilot study validated the research questions, sampling design, measurement and data analysis methods developed for a large‐scale study, with some minor amendments.
Field-scale Assessment of Phytoremediation of a Flare-Pit Soil in Carlyle, SK: Year 4 Overview
Resource
A cooperative trial to test the use of vegetation to enhance treatment of soils contaminated with weathered petroleum hydrocarbons (PHCs) was initiated in 2002. Experimental protocols were adapted...
Guide to Variance Justifications for Reclamation Certification of Wellsites and Associated Facilities: Stakeholder Review and Field Verification
Resource
Practitioners tested the Guide to Variance Justifications on four of those sites; three had been previously approved and one had been submitted and was pending a decision.
Identification and Characterization of Abandoned Padded Wellsites Using Remote Sensing
Resource
In 2018, the Petroleum Technology Alliance of Canada (PTAC) initiated a multi-stage project on the reclamation certification process for sites that were constructed using imported mineral soil pads in...
Motorized Activity on Legacy Seismic Lines: A Predictive Modeling Approach to Prioritize Restoration Efforts
Resource
Natural regeneration of seismic lines, cleared for hydrocarbon exploration, is slow and often hindered by vegetation damage, soil compaction, and motorized human activity. There is an extensive...
Northern Biochar for Northern Remediation and Restoration
Resource
Biochar is a soil amendment that results from heating various biological ingredients, such as wood, fish or animal bone under oxygen limited conditions and has proven to promote plant growth, as well...
