Midale, Weyburn, Canada

A fractured carbonate reservoir with a preferential fracture orientation. Production performance predictions were developed for a waterflood which commenced in 1962 and a CO2 flood demonstration project which commenced in 1992. Commercial CO2 flood expansion development plans and economics were developed. Performance of multilateral horizontal well drilled both parallel and perpendicular to the preferential fracture orientation were matched analytically in order to estimate ultimate recovery efficiency for the CO2 flood and waterflood.
