International Classification:

E21B 49/00
G01V 3/14

US Classification:

7315202, 342303, 702 8

Abstract:

Data from a string of multiple formation evaluation data sensor are evaluated by an expert system. Based on the analysis, the logging speed is increased if all the sensors justify it, and is reduced if any of the sensors require a reduced logging speed. Alternatively, the sensitive volume of a NMR sensor is altered based on a determination of a fraction of the sensitive volume that includes a borehole fluid. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

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.
