Abstract
A system can include a white light source; an ultraviolet light source; a digital machine vision camera for capture of imagery of rock cutting samples illuminated by the white light source and the ultraviolet light source; and circuitry operable to generate calibrated imagery of rock cuttings samples with contrast between rock cuttings samples with hydrocarbons and rock cuttings samples without hydrocarbons.
Claims20
A system comprising:
- a white light source;
- an ultraviolet light source;
- a digital machine vision camera for capture of imagery of rock cutting samples illuminated by the white light source and the ultraviolet light source;
- and
- circuitry operable to generate calibrated imagery of rock cuttings samples with contrast between rock cuttings samples with hydrocarbons and rock cuttings samples without hydrocarbons.
A method comprising:
- illuminating a rock cuttings sample with white light and ultraviolet light;
- capturing imagery of the rock cuttings sample;
- and
- characterizing the rock cuttings sample based at least in part on physical characteristics derived from the imagery and based at least in part on fluorescent emissions derived from the imagery.
Non-transitory one or more computer-readable storage media comprising computer-executable instructions executable to instruct a computing system to:
- illuminate a rock cuttings sample with white light and ultraviolet light;
- capture imagery of the rock cuttings sample;
- and characterize the rock cuttings sample based at least in part on physical characteristics derived from the imagery and based at least in part on fluorescent emissions derived from the imagery.
