Executive Summary
PTAC has engaged InnoTech to test three alternate products which are believed to have superior properties compared to oilwell cement for the purposes of certain well remediation applications and casing plugging. This report is for Phase 1 testing of a resin provided by Challenger Technical Services Ltd. (Challenger). The resin is in development and has not undergone field trials. Challenger intends to use this resin for well remediation in applications behind well casing.
The objective of using a resin in well remediation and abandonment procedures is to reduce costs and to safely improve outcomes while providing permanent barriers for hydraulic isolation in wellbores. With specific applications of this resin, the inventory of leaking wells and inactive wells is expected to be reduced.
