摘要
A method for depth determination of drilled rock cuttings is disclosed. The taggant is injected and transported downhole along the mud stream (204, 205) and attaches to the rock cuttings. Taggant impregnated cuttings are detected at the surface (108) based on molecular weight, emission wavelengths or radio frequency characteristics for encoding the taggant. The identification code identifies the depth of the drill bit when the particular batch of the taggant is released into the mud. The detection data, in addition to mud properties, flow rates, drill volume and penetration rates, formation characteristics, and well specifications are transferred to and analyzed by a taggant analysis and control engine (202). The taggant analysis and control engine (202) controls an IoT controller (203) that adapts the parameters of the taggant injection pump (206) to achieve an intelligent controlled release to optimize the depth characterization process.
