Abstract
One aspect relates to a method of installing a transmission system in a hydrocarbon production well. The transmission system is operable for transmitting power and/or control signals down the well or for transmitting data signals back up the well. The well comprises a main well bore, a production tubing inside the main well bore and a branch off the production tubing. The branch comprises a side track tubing. The method includes: providing a sensor and/or load assembly in the branch; installing a first inductive coupler of an induced current transmission arrangement around the production tubing in the main well bore, and connecting the sensor/load assembly to the first inductive coupler via a communication link. Another aspect relates to a hydrocarbon production well installation.
