Objectives

CSEMP - CO2 Sequestration and Enhanced Coalbed Methane Production Pilot

§Scientific / Technical§Extended pilot to test coal seam response to

CO2 injection, determination of CO2 storage parameters, evaluate ECBM production potential and establish storage, monitoring and verification parameters

5


Objectives cont ...

§Specific§Evaluate geotechnical, physical and chemical

interaction of CO2 and Ardley coal (incl.desorption and miscibility properties)

§Volume/rate of CO2 injection and dispersion§Volume/rate incremental methane production§Advance research on how CO2 sequestration

could effectively help reduce WCSB gas plant CO2 emissions from 8.8 Mtonnes

§Determine the effect of CO2 injection and storage on CBM production from adjacent wells

6


Objectives cont ...

§Determining response of coals to injection of CO2 over an extended time period (6-18 months)

§Evaluate the impact on ground water and ground water production, if applicable

§Consider the effects of mixed gas (CO2 and N2) on storage and CBM production

§Establishing design basis, cost, and operating parameters for CO2 injection and storage, reservoir and surrounding aquifer fluid dynamics and enhanced CBM production

7


Benefits

§CO2 capture and storage underground has the potential to contribute substantially to Canada’s Kyoto targets

§Understanding coal as a reservoir (production/storage)

§ Leveraging participant expertise

8


Benefits cont ...

§Opportunity for advancing research in 3 primary areas of sustainable and responsible development:§ CO2 capture, CO2 transport, underground engineering

and CO2 storage

§ Enhanced CBM recovery and production§ Technology related to monitoring and verification

§Assist with establishment of regulatory framework (CBM, GHG, reporting)

§Possible application at other pilot sites for future large-scale CO2 injection project and commercial ventures

9


Background

§Initiated in late 2001§Suncor, EnCana, MGV and TCPL§ARC, AERI, ASRA, EnvCda, SDTC, UofC

§Initial Site Red Deer (38-28W4)§ Low permeability

§New location Pembina (46-7W5)§ Two producing CBM wells 7-28 and 12-28§Additional participants joined and additional

funding sought

Injection & P3 Well Design

22


Micro-Pilot Objectives

§Determine the reservoir pressure, permeability, and near wellbore damage

§Accurately measure data while injecting into and producing from a single well

§Match the measured data with a comprehensive coal gas reservoir simulation model to obtain estimates of reservoir properties and sorption behavior

§Use the calibrated simulation model to predict the location of the P3 well

23


Surface Facilities

§Production facilities§SCADA gas and water rate measurement§ 2 phase separator§Continuous gas composition monitoring§Bottom-hole pressure monitoring§Pumping equipment

§Injection facilities§ Liquid CO2 storage tank§CO2 injection pump skid§ 200 KW Vaporizer
