This conversation with Dave Hills is about the geology of the first large-scale CO2 enhanced oil recovery project kicking off in the Leduc Clive Field in Central Alberta, based on Dave Hill's  technical article titled “CO2 Enhanced Oil Recovery in Alberta”.  Why is the Leduc formation an ideal reservoir for carbon dioxide injection?   What kind of geologic features impact the geomodelling and simulation of the fluid flow?  How much oil can be recovered from the historic reservoir with tertiary recovery?  Has this been done before?  What is the ATCL?May this exchange serve to expand your geological knowledge on the go.For more information go to www.stoneconsulting.infoCitation: Hills, D.
