Zusammenfassung:An imaging device (124), laser(s) (190, 192), lag calculation, and/or volume calculations are used to determine cuttings volume per unit depth. A projected or theoretical volume can be calculated based on parameters of the borehole being drilled. At the surface of the borehole, cuttings can be captured in a shaker screen (108). The volume of the cuttings can then be directly measured on the shaker screen. Deviations from a projected volume can be logged and notifications can be communicated on and/or offsite of the borehole. Additionally, size and shape of cuttings can be logged. Deviations from projected size and shape can also be logged. Various hydrocarbon recover}' operations can be altered based on results of the cuttings analysis and other indicators of improper hole cleaning. For instance, the drilling can be stopped, or a direction of the borehole can be altered.
