DOWNHOLE COMMUNICATIONS USING SELECTABLE MODULATION TECHNIQUES

摘要

A system that is positionable in a wellbore in a subterranean formation can include a first transceiver that is positionable external to a casing string in the wellbore. The first transceiver can wirelessly transmit data using a modulation technique that is selected from among multiple modulation techniques based on a fluid property of a fluid in the wellbore and a property of the subterranean formation. The system can also include a second transceiver that is positionable in the wellbore and operable to receive the data.
