  • In-situ downhole cuttings analysis
    Patent number: 9617851
    Abstract: Systems, devices, and methods for evaluating cuttings entrained in a downhole fluid in a borehole intersecting an earth formation. Methods may include using at least one sensor to produce information responsive to a reflection of an emitted wave from downhole cuttings in the borehole, wherein the information is indicative of a parameter of interest relating to the downhole cuttings; and processing the information using at least one processor to estimate the parameter of interest. Methods may include using the at least one acoustic sensor to produce corresponding information from each of a plurality of azimuthally distributed orientations about a bottom hole assembly (BHA); and using the at least one processor to estimate from the information from each of the orientations an azimuthal variation of the parameter of interest. The at least one sensor may include acoustic sensors, electromagnetic sensors, and/or optical sensors.
