Abstract:
1. A system for reducing disturbance during in-well fiber optic sensing, the system comprising: a device insulated to be disturbance-resistant, the device in a fiber optic communication path between a source and a target configured to be received in a well, the device configured to receive a parameter sensing signal transmitted from the source to the target, the device configured to produce a reference signal, wherein the device includes a first fiber optic cable to receive the parameter sensing signal from the source, the first fiber optic cable disposed in disturbance dampening gel; a second fiber optic cable connected in-line with the first fiber optic cable, the second fiber optic cable to transmit the parameter sensing signal to the target; and a signal interrogation system connected to the device in the fiber optic communication path, the signal interrogation system configured to:
