摘要
Disclosed is an apparatus, method, and program product for steering a drill bit within a pay zone in a lateral well. The method includes receiving acoustic signature data from a downhole processor assembly. The acoustic signature data includes an amplitude spectrum and one or more acoustic characteristics evaluated from an acoustic signal provided by a sensor arranged adjacent to a drill bit and generated in real-time as a result of rotational contact of the drill bit with encountered rock in the lateral well during drilling. The method further includes comparing the received real-time acoustic signature data to predetermined acoustic signatures determined for a plurality of rock samples, and identifying a lithology type of the rock being encountered by the drill bit based on the comparison. Further, the method includes steering the drill bit in a predefined direction, in real-time, based on the identified lithology type of the rock, for maintaining the drill bit within the pay zone of the lateral well.
