This paper will present all results and discussion of Burgan 3rd sandstone reservoir, part of its pore level micro-analyses and characterizations. One rock fragment, situated at a depth of 4785 feet, is selected for the analysis. After sample preparation, several images are captured with a Scanning Electron Microscope (SEM) at different depths of magnification. According to Al-Bazzaz and Al-Mehanna (2007), a process, where measuring petrographic images into petrophysical parameters such as porosity, permeability, MHR and measuring sand-grain sizes at their native selected spaces, is documented. For the purpose of this study, the pore networks as well as the sand-grain particles are studied in space-domains between a lower bound of 50 µm and an upper bound of 2 mm. The ultimate goal for this study, where consistent data is measured and delineated from different field-of-view (FOV), is to investigate up-scaling porosity, matrix permeability, MHR and grain-size at micro-levels. Another objective of this study is to develop a simple statistical model of these measured petrophysical parameters obtained from up-scaling different field-of-view (FOV) scale sizes. The proposed sample size scale starts with 600X-(FOV) (adequate for recognizing features at 50 µm-scale size), then gradually escalate to 450X-(FOV) (recognizing features at 100 µm-scale size), 300X-(FOV) (recognizing features at 200 µm-scale size), 100X-(FOV) (recognizing features at 500 µm-scale size), and finally, 40X-(FOV) (recognizing features at 2 mm-scale size).
