Abstract

An interface of fluid phases is created by unbalanced molecular attracting and repulsive force. Evaluating the gas-liquid interfacial tension is very important and major interest in injection processes. The interfacial tension between gas and liquid phases can be measured by different methods in the reservoir and surface condition. VIT (vanishing interfacial tension technique) is a laboratory method that calculates interfacial tension for mixture of oil-gas in the series of pressure. Estimating the amount of the minimum miscibility pressure (MMP) is taken to be the pressure at which the interfacial tension tends to zero when plotted against pressure. The surface tension calculation is done by image processing of sessile and pendant drops of crude oil enclosed in a surrounding medium of the injection gas. In this paper use a computer program for processing and digestion the shape of a pendant drop has been brought.
