Abstract

Light transmitted through a thin section of reservoir rock whose pores are filled with blue-dyed epoxy is passed sequentially through red, blue and green filters and the density levels in the filtered images thereafter converted into pixels. The intensity, hue and saturation are then calculated from the red, blue and green components in each scene pixel. From the calculated values of intensity, hue and saturation, the pixels representative of pores and pores underlain by mineral are separated from the non-pore representative pixels.
