Title: Calgary Environmental Network Lunch and Learn: "Learnings from Review of Drilling Waste Compliance Option Checklists"

When: April 16, 2019 from 12:00-1:15 pm

Where: 2nd Floor, 105 12 Ave SE, Kahanoff Centre, Calgary, AB or Webinar

Speaker: Jim Purves, Technical Advisor, North Shore Environmental Consultants

Mr. Purves is a Professional Agrologist with over 20 years of experience in the environmental and agricultural industries. As a Technical Advisor, Mr. Purves provides technical support, senior report review as well as mentorship and staff training to his team members.


The Compliance Option Checklist and Calculation Tables are used to evaluate whether the drilling waste disposal area (DWDA) may pose a risk to the environment. Industry has accumulated years of Phase 1 and 2 data since the inception of this guideline in 2012. Mr. Purves reviewed hundreds of Phase 1 Compliance Option triggers to determine if they resulted in false positives or negatives, compared to the actual Phase 2 outcomes. The review raised questions whether relevant triggers, such as those related to unknown additives, drill-stem test (DST) assumptions, salinity and hydrocarbon thresholds, or scope of professional judgement require adjustment? A formal review of the Compliance Options could potentially provide improved confidence for the number of Phase 2’s that should be completed and enable new discussions with AER as to whether the Compliance Options should be modified based on our current understanding and relevant Phase 2 results.
