... communicating offset wells ( Figure 1 ). Using an Alberta Innovates–Technology Futures (AITF) CSI model, a history match was obtained for CSI Cycle 1. Eleven different potential injection/production strategies were then evaluated for Cycle 2 and the simulation results were used in the design of this cycle. One...

The efficiency of the pre-heat can be affected by several factors, with completion type being one of the most important...

... Abstract In oil sands in situ operations using steam-assisted gravity drainage (SAGD), achieving effective communication between the injector and producer with a reasonable conformance is crucial for the success of SAGD conversion and the following ramp-up phase. The start-up operation normally...
