Abstract
In November 1997 the CREWES Project at the University of Calgary, with assistance from Boyd Petro‐Search Consultants and PanCanadian Petroleum, recorded a unique, high‐resolution 3-C, 2-D seismic survey at the PanCanadian‐owned Blackfoot Field some 50–55 km east of Calgary, Alberta, Canada. The producing formation is a Lower Cretaceous, cemented, glauconitic sand deposited as incised channel‐fill sediment above the Mississippian carbonates. The sandstone is about 1500 m below surface. Its thickness ranges up to 45 m. Average porosity is near 18%. Cumulative production throughout southern Alberta exceeds 200 million bls oil and 400 billion ft3 gas.
