Abstract
Methods and systems for decoupling a component signal. A method may include disposing a logging tool in a wellbore, capturing a signal response with the logging tool from a formation, wherein the logging tool includes a first receiver, a second receiver, and a third receiver, averaging the first receiver and the third receiver to generate a first pseudo antenna, generating a second pseudo antenna which includes an azimuth offset, employing an attenuation factor and expansion factor to generate a pseudo collocated antenna. Furthermore combining responses from a transmitter, the first pseudo antenna, the second pseudo antenna, and the pseudo collocated antenna to decouple a component, which may determine the boundaries of a formation from the component. A well measurement system for decoupling a component may include a logging tool, conveyance, and information handling system. The logging tool may include a first downhole tool, a receiver, and a transmitter.
