Abstract Porosity and permeability analyses were performed on a tight sand core sample from the Big Lake field, Cooper Basin, South Australia. This process involved the design and construction of an experimental system capable of measuring these characteristics. Permeability analysis involved a comparison of the data obtained from this system with the data modelled by a pre-existing theoretical anisotropic stress-dependant permeability model, engineered specifically for the Big Lake field region. Whilst the results were greater in magnitude than expected for a tight stand reservoir, the trend in data did fit the trend expected by data modelled for this region. Porosity analysis involved comparing two methods of photomicrography; optical microscope and SEM imaging. These analyses focused on pore structure, including porosity and pore size distribution. It was concluded that the sample is on the more porous side of the ‘tight’ reservoir rock, with an average porosity of 10.22% and a pore size distribution comprised primarily of typically more permeable micro-fractures, explaining why the sample is more permeable than expected. Overall it was determined that SEM photomicrography is more useful as a pore analysis tool than it’s optical microscope counterpart, primarily due to the higher magnification capabilities. These findings contribute to improving the relatively new and developing field of tight rock characteristics analysis within Australia.
