Abstract
A mineralogical record of whole core is produced by translating whole core relative to a X-ray diffraction source and detector and summing the resulting X-ray diffraction spectra from various surface portions of the core over an interval of the core.
Claims15
A nondestructive method using X-ray diffractometry for generating a mineralogical record of whole core taken from a wellbore comprising:
- providing a core taken from a wellbore;
- successively X-ray irradiating various surface portions of the core producing from the irradiated various surface portions diffracted X-radiation;
- measuring intensity of diffracted X-radiation from irradiated various surface portions as a function of diffraction angles;
- and
- summing the resulting measures of intensity as a function of diffraction angle from irradiated various surface portions;
- wherein
- the steps of successively irradiating various surface portions, measuring, and summing are continued over sufficient various surface portions for providing an X-ray diffraction spectrum of the core representative of mineralogy of the core.
