EOR & WEYBURN CASE STUDY
Global CCS Institute
WORKSHOP FOR CIVIL, CHEMICAL, ELECTRICAL, ENVIRONMENTAL AND MECHANICAL ENGINEERS:
INTRODUCTION TO CAPTURE, USE AND GEOLOGICAL STORAGE OF CO2
October 13-14, 2014
DF CFE Technology Museum
SUPPORTED BY:
3. IEAGHG Weyburn-Midale CO2 Monitoring
& Storage Project (WMP) 2000 to 2012
Commercial EOR operations in
Weyburn and Midale oilfields
utilise anthropogenic CO2
Over 25Mt of CO2 injected and
stored since 2000
WMP has used these sites to
study technical aspects of CO2
geological storage
4. CO2 Source: Great Plains Synfuel Plant
• 250 mmscfd CO2 by-product of
coal (lignite) gasification
• approx. 8000 tonnes/day
suitable for EOR
• CO2 purity 95% (less than 2%
H2S)
• 180 mi pipeline (14 in & 12 in)
built & operated by Great Plains
9. Passive Seismic Monitoring
• Documentation of time,
magnitude and location of
seismicity:
• Public assurance
• Integrity of the sealing units
• Injection control
10. False Claims of Weyburn CO2 Leakage
• source of problems according to local consultant…
• ‘clearly anthropogenic CO2 injected into Weyburn reservoir’
- CO2 concentrations
d13C isotopes
- Methane concentrations
- Ethane+ concentrations
- ‘oil’ sheen on dugout
- bubbles, foam, noises…
- dead animals
