摘要:
A method for estimating a petrophysical parameter from a rock sample includes making a three dimensional tomographic image of the sample of the material. The image is segmented into pixels each representing pore space or rock grain. Porosity of the sample is determined from the segmented image. An image of at least one fracture is introduced into the segmented image to generate a fractured image. The porosity of the fractured image is determined. At least one petrophysical parameter related to the pore-space geometry is estimated from the fractured image.
摘要:
A method for estimating effective atomic number and bulk density of objects, such as rock samples or well cores, using X-ray computed tomographic imaging techniques is provided. The method effectively compensates for errors in the interpretation of CT scan data and produces bulk densities which have lower residual error compared to actual bulk densities and produces bulk density—effective atomic number trends which are consistent with physical observations.
