Abstract | Analog signals corresponding to color images or pixels of a thin section of a rock reservoir are digitized and then filtered to isolate the pixels representative of pores in the thin section. The pores so isolated are then counted, measured for their total pore perimeter and labelled. The pixels representative of pores are then progressively eroded and dilated, pursuant to which one layer of pixels on the surface is eroded and, if a seed pixel remains, one layer of pixels is added. Thereafter, the original object undergoes two successive erosions followed by two dilations if a seed pixel remains. Successive iterations of the erosion and dilation cycle continue until the last erosion eliminates the seed pixel. The number of pixels lost with each degree of erosion constitutes a pore spectrum consisting of information relating to the total amount of pore image lost each erosion-dilation cycle, the pore size lost each erosion-dilation cycle and the pore roughness lost each cycle. The spectra developed from the erosion-dilation cycle and corresponding to each pore complex are then analyzed into end members and the end member proportions for each field of view are calculated. |
