Abstract
Example systems and methods are described for performing multilateral well sensing in a downhole environment. In an example system, a cased parent wellbore and a cased lateral wellbore intersect at a lateral junction. A sensor is deployed within the cased lateral wellbore that communicably couples to a transmitter module, wherein the transmitter module is deployed within the cased lateral wellbore downhole of the lateral junction and configured to generate acoustic signals. An optical fiber cable is deployed within the cased parent wellbore and configured to receive acoustic signals transmitted by the transmitter module in the cased lateral wellbore.
Claims17
A system for use in a cased parent wellbore and a cased lateral wellbore intersecting at a lateral junction, comprising:
- a sensor deployed within the cased lateral wellbore that is communicably coupled to a transmitter module, wherein the transmitter module is deployed within the cased lateral wellbore downhole of the lateral junction and configured to generate acoustic signals;
- and
- an optical fiber cable deployed within the cased parent wellbore and configured to receive acoustic signals transmitted by the transmitter module in the cased lateral wellbore.
A method, comprising:
- detecting a measurement data at a sensor deployed in a cased lateral wellbore;
- transferring the measurement data to a transmitter module that is communicably coupled to the sensor;
- converting the measurement data into an acoustic signal correlated with the measurement data;
- and
- transmitting the acoustic signal to apply acoustic pressure on an optical fiber deployed within a cased parent wellbore that intersects the cased lateral wellbore.
