Encana has injected carbon dioxide into the Weyburn oil reservoir since September 2000 as part of an Enhanced Oil Recovery (EOR) operation. CO2 storage in the reservoir is being evaluated during injection.

Abstract
Encana has injected carbon dioxide into the Weyburn oil reservoir since September 2000 as part of an Enhanced Oil Recovery (EOR) operation. CO2 storage in the reservoir is being evaluated during injection. Systematic soil gas measurements (including CO2, CO2 flux, O2, CH4, radon, thoron, helium, sulphur species and light hydrocarbons) form part of this evaluation. Data from July-September 2001 provided baseline values. Results from September 2002 give an insight into changes in near surface data. In situ radon probes are monitoring diurnal and seasonal variations. Future datasets will be essential for assessing the CO2 storage integrity of the reservoir rocks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
