Abstract
A distributed acoustic system (DAS) may include at least one laser that transmits a continuous wave (CW) light, a pulser optically connected to the at least one laser to receive the CW light from the at least one laser and form a light pulse, and a splitter optically connected to the pulser to optically split the light pulse into a plurality of light pulses. The DAS may further comprise a circulator optically connected to an output of the splitter, a sensor fiber attached to the circulator, and a reference coil disposed on the sensor fiber between the circulator and a first section. A method for using the DAS may include transmitting one or more light pulses from a laser into the DAS, generating an interrogator specific noise profile for the reference wellbore, and generating an application specific noise profile for a first sensor fiber disposed in the reference wellbore.
