1 Aquistore Saskatchewan s Deep Saline CO 2 Storage Research Project Presented by Kyle Worth, P.Eng., PMP to INRS, Quebec City April 19, 2012

2 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.

3 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

4 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

5 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

6 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

11 Hydrogeology - TDS Total Dissolved Solids (TDS) Injection site: 300,000 mg/l in Deadwood Compared to: 35,000 mg/l in Seawater 7.1 mg/l in Rainwater Approximate Project Location

12 Injection Well Design Well depth 3300m to reach Deadwood in Estevan area Surface 13-3/8 casing to ~500m Production 7-5/8 casing to ~3300m 7-5/8 production casing for operability with 4.5 tubing Achieves evaluation and potential injection objectives Coring, DST, Logging program

13 Well Evaluation Program Coring Multiple intervals of reservoir, caprock and seals Drill Stem Tests -2 Logging TD section Gamma Ray / SP / Resistivity / Density / Neutron Sonic Compressional and Dipole Shear Nuclear Magnetic Resonance Formation Elemental Analysis MDT formation pressure & samples 4 MDT minifrac 3 MDT vertical interference test 2 Logging Cased hole Ultra sonic cement imager

14 Observation Well Observation Well Schematic Geology over Instrumented Section Aquitard 1 Aquifer 1 Fluid Sampling Port allows downhole fluids to be collected for comparison to wellhead fluid samples Geophone Strings (2-9 phone lines - 18 phones in total) phones spaced at approximately 25 m with a minimum 5 phones below injection horizon Sensitivity of geophones sufficient for VSP, passive seismic and crosshole tomography measurements All instrumentation is run casing conveyed to allow time-lapse logging to occur unimpeded Caprock Aquitard Injection Horizon Pressure/Temp Gauges Pressure gauges will be placed across up hole aquifer horizons Time-Lapse Logging Underburden Fiber Optic based Distributed Temperature Sensing System

15 Measurement Monitoring & Verification Program Designed for: (1) project/plume monitoring; (2) public assurance; (3) research objectives Key Elements: Baseline 3D seismic survey Time-lapse seismic surveys Permanent seismic array Real-time pressure & temperature monitoring Passive seismic Downhole fluid sampling Time-lapse logging & VSP s Groundwater & Soil gas monitoring Downhole cross-well electrical monitoring Surface-to-downhole electrical monitoring Surface controlled-source electromagnetic monitoring Surface gravity Permanent tiltmetres Cross-well seismic 15
