For those who are interested, Denbury did a webcast on the 6 September 2011. The presentation is 45mins long but Grieve is mentioned briefly (around the 19.20 minute mark). The presentation will be available for the next 28 days.
Interesting points I noted: - Grieve could potentially be the first to commence production (early 2013) out of all of Denbury's EOR projects in the Rockies; - On slide 19, Grieve is noted as having an estimated 6MMBbls of probable and possible reserves; - Denbury appear to have control of the majority of Co2 sources in the Rockies now with their recent acquisition of Riley Ridge so i'm not sure how Elk is planning expand through the increase in the number of EOR projects it has in the Rockies unless they plan on only going down the Chemical Flood route which doesn't appear to be as efficient as Co2 flooding.
