A theoretical model of foam as a consolidating continuum is proposed. The general model is applied to foam in a gravity settler. It is predicted that liquid drainage from foam in a gravity settler begins with a slow drainage stage. Next, a stage with faster drainage occurs where the drainage rate doubles compared to the initial stage. The experiments conducted within the framework of this work ...

Steam assisted gravity drainage is a thermal method for enhanced bitumen recovery. In this method, steam injected to and heavy oil reduce the viscosity make mobile. However, early breakthrough of in some parts well results loss required amount contact with cold bitumen, poor distribution chamber. This limits production increases SAGD operation cost. Autonomous inflow control valve (AICV) able p...

The high recovery performance of steam-assisted gravity drainage (SAGD) makes it a popular option for heavy oil resources. Currently, most the reservoirs developed by SAGD in China are late development phase, with energy consumption due to reduced thermal ef?ciency. use wind-down processes involving CO2 combination steam is considered as viable alternative limit consumption, and also reduce amo...
