Aquistore Saskatchewan s Deep Saline CO 2 Storage Research Project Presented by Kyle Worth, P.Eng., PMP to INRS, Quebec City April 19, 2012
Petroleum Technology Research Centre Mission: To develop world-leading enhanced oil recovery and CO 2 storage technologies that ensure sustainable and environmentally-sensitive development of Canada s energy resources. Non-Profit Research & Development Collaborative partnership with Industry, Government and Research Organizations Founded in 1998 by: Natural Resources Canada Ministry of Energy and Resources Saskatchewan Research Council University of Regina PTRC is the 10+ years managers of the IEA GHG Weyburn-Midale CO 2 Monitoring and Storage Project.
Aquistore Project Project Objectives: Demonstrate CO 2 storage in deep saline formation is a safe, workable solution to reduce greenhouse gas (GHG) emissions Develop best methods & technologies to monitor GHG Involve research institutions, policy makers, industry, and public 3
Project Overview CO 2 storage research monitoring project Designed to inject 2000 tonnes CO 2 /day $22.3M in sponsorship secured to date Buffer protection and long-term storage option for SaskPower s Boundary Dam Carbon Capture Project
Phase 1: Demonstration & Evaluation site selection, permits, agreements, community engagement risk assessment, seismic surveys, monitoring programs evaluation/injection well observation/monitoring well test injection trucked in CO 2 5
Phase 2: Commercial & Monitoring On going monitoring and observation On going community engagement Pipeline tie-in CO 2 from Boundary Dam Power Station World s first commercial carbon capture technology applied to a coal plant and the sale of CO 2 for EOR/storage 6
