Developing and evaluating a model for Surfactant-Foam Flooding

Many reservoirs are considered unsuitable candidates for Enhanced Oil Recovery. Surfactant-Foam flooding, also referred to as Low-Tension-Gas flooding, could be a solution to enhance the oil recovery in tight, saline or high temperature reservoirs. SF-flooding combines reduction of the oil-water interfacial tension by surfactant, with mobility...

Modelling the effect of oil on foam with the wave curve method

Enhanced oil recovery by gas injection can show excellent displacement efficiency but may suffer from poor sweep efficiency. A promising method to overcome poor sweep efficiency in gas-injection enhanced oil recovery processes is foam injection. The effect of oil saturation on foam stability is complicated and not fully understood. Complexity in...
