..., a multiphase flow phenomenon arises. When there is multiphase flow, flow patterns should be considered. It is known that, there is a difficulty to predict hydraulic behavior of gas-liquid mixtures due to this flow pattern dependence. During a drilling operation, one of the parameters that should be well...

This is a pre print and subject to correction. Abstract With SAGD operations, it is often inevitable to have shut-in time and turnaround periods because...

.... Three pairs of SAGD operation began in April of 1997 after three months of circulation. Many interesting characteristics were identified in the injection and production history. During the first year of operation, pressure and oil production rates decreased when steam injection rates were reduced. After...
