Description
Dynamic investigation of fluid flow in rock samples is essential to meet the goals of oil and gas projects such as underground enhanced oil recovery and gas storage. In order to develop an efficient fluid model, the X-ray computed microtomography technique (XCT) was employed to scan limestone and sandstone samples from an indigenous Iranian reservoir. Six representative real samples were scanned on the ID19 microtomography beamline at the ESRF، with appropriate resolution and X-ray energy. The reconstructed volumes were analysed using the 3D data analysis software packages. The following crucial quantities could be identified: the amounts and spatial distributions of open and closed porosity; the pore diameter distribution; the tortuosity values and tortuosity maps in the samples, and the specific interface area between pores and solid matter, from which the medium characteristic length can be derived.
