A hybrid telemetry system includes a plurality of telemetry networks configured to communicate a modulated signal representing digital data along adjoining sections of a pipe string. The plurality of telemetry networks may each be optimized or particularly suitable for the configuration of the pipe string, the well, and/or the environment of the well occurring in each of the adjoining sections. Some of the plurality of telemetry networks may overlap to provide redundancy of the communication of the digital data.

Serial hybrid downhole telemetry networks

A method of steering a drilling operation of a well using rock stress measurements. The method includes obtaining well data from at least one logging while drilling tool in the well, where the well data includes stress direction information, generating, using a central processing unit (CPU), a well trajectory using survey data from the well, where the well trajectory includes a borehole direction, determining, using the CPU, a direction of minimum horizontal stress using the well data, and comparing, using the CPU, the direction of minimum horizontal stress to the borehole direction to determine that a directional criteria is not satisfied. The method further includes in response to determining that the directional criteria is not satisfied, generating an updated well trajectory that satisfies the directional criteria and adjusting the drilling operation using the updated well trajectory.
