Two Dimensional Displacement of Oil by Foam
Abstract/Contents
- Abstract
- This research program extends previous research performed by Mahmood (1986) in which he developed a conceptual model to match flow recovery and pressure drop of foam containing systems. The objective of the original study was to develop a conceptual model from the visual observations of the flow patterns and arrive at a mathematical model which could be used to forecast flow recovery and pressure drop using foam. This previous study was performed using a single geometrical shape and one surfactant at one concentration. Further research was suggested. This present report expands upon the previous study by describing laboratory research with data on the recovery and pressure drop of three surfactants at three different concentrations. The model used in this study had a rectangular shape and a scale approximately one-half the length, one-half the width and a slightly greater depth in comparison to the model used by Mahmood. The experimental procedure consisted of injecting surfactant solution and gas as a foam into the apparatus which contained oil and was at irreducible water saturation. The foam was injected into the model which then displaced the oil, and the liquid and gas produced were collected along with data on the pressure drop across the model. The conceptual model of Mahmood's performed well in forecasting oil recovery but did not fit the pressure data very well in his dissertation. The research reported here confirms these results.
