Foam has been used in petroleum industry as a fracturing fluid and a drilling circulation fluid for many years. Proper determination of volumetric requirements for gas and liquid phase of foam during drilling and fracturing applications is directly related with an accurate foam characterization. It has been observed that, bubble size and texture of foam has an influence on foam rheology, however, no mathematical description has been introduced for their effect. The idea behind conducting this study is to get a more comprehensive method of foam rheology definition in which the bubble size and texture effects of the foam are considered. Three different analysis methodologies are introduced; i) Generalized Volume Equalized approach, ii) Generalized Volume Equalized Approach + Image Processing data, and iii) Image Processing data only. The necessary information including the rheological information and image data is acquired from the developed set-up for this study. It has been observed that, the pressure losses could be predicted as a function of bubble size, circularity, and general rheological parameters, in ±20% certainty limit. It is also observed that using only the image information could also be used for characterizing the foam in an accurate and fast manner.
