摘要:
An apparatus and method for estimating a parameter of interest of an earth formation involving alignment information between receivers and their corresponding oriented transmitters. The method may include generating signals indicative responses to energy transmitted into an earth formation; estimating differences in alignment between transmitters and receivers; using the estimated differences in alignment to compensate for misalignment; and estimating a parameter of interest using the misalignment compensated signals. The apparatus may include a bottom hole assembly with one or more oriented transmitters, one or more oriented receivers, one or more alignment sensors, and at least one processor configured to compensate for misalignment using information about difference in alignment between the at least one oriented transmitter and at least one oriented receiver.
