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.

Claims

1. A downhole gauge telemetry system for a multilateral well, comprising:

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.

2. The downhole gauge telemetry system of claim 1, wherein the first and second wireless transceivers are acoustic wireless transceivers.

3. The downhole gauge telemetry system of claim 1, further comprising a data acquisition module communicatively coupled to the second wireless transceiver.

4. The downhole gauge telemetry system of claim 3, further comprising at least one sensor located in the lateral borehole and communicatively coupled to the data acquisition module.

5.
