Foam Stability in Presence of Oil: A Simulation and Experimental Study

This thesis investigates bulk foam stability in absence of oil, and in presence of oil (hexadecane). Foam in absence of oil was produced by sparging nitrogen at a fixed flow rate through the surfactant solution. Foam in presence of oil was produced by stirring a mixture of surfactant and oil with an immersion mixer. The behavior of foam in...

Injectivity errors in foam EOR

Simulators play a crucial role in EOR reservoir modeling. One of the big problems with the simulation of gas injection in SAG foam processes, is that foam collapse near the injection well is poorly represented in the simulator well model. This paper focusses on the question whether a simulator using the Peaceman equation for a homogeneous...
