Downhole gauge telemetry system and method for a multilateral well

Abstract

A downhole gauge telemetry system for a multilateral well includes a first wireless transceiver located in a primary borehole of the multilateral well, a second wireless transceiver located in a lateral borehole of the multilateral well, a wireless connection between the first wireless transceiver and the second wireless transceiver through which the first and second wireless transceivers exchange data, and a surface transceiver communicatively coupled to the first wireless transceiver.
