Leak Detection in Wells on the Use of Distributed Temperature Gradient Sensing with DAS FEBUS A1

The aim of well integrity interventions using DFOS (Distributed Fiber Optic Sensing) is to significantly reduce the duration of these operations as well as their cost and to provide additional information….We perform all measurements using a wireline deployment and monitor the well integrity in real-time….The main advantage of using DTGS with DAS is its sensitivity to small leaks….To conclude, we obtain consistent DTGS data using the DAS FEBUS A1 technology at low frequencies….The combination of DTGS with the DAS FEBUS A1 and high frequency DAS (flow, tube vibrations) allows simultaneous and real-time qualification and quantification of leaks in wells.
