Silixa Ltd will be showcasing its new pioneering intelligent distributed acoustic sensing system (iDASTM) at the SPE Intelligent Energy 2012 conference in Utrecht, March 27-29.
iDAS enables high quality digital recording of acoustic waves at every point along many kilometres of optical fibre cable up to frequency >100kHz with a wide dynamic range (>90dB). The distributed sensing system is used in a great variety of well surveillance applications including distributed flow metering, distributed seismic imaging, fracture mapping and well integrity monitoring.
iDAS technology can be combined with Silixa’s world-leading distributed temperature sensor, UltimaTM DTS, to provide a continuum of benefits throughout the life of a well from exploration to drilling and completion, production and reservoir management. Applications include: seismic appraisal at the borehole, cement evaluation, monitoring fracturing and fracture analysis, flow profiling, monitoring casing leaks, gas lift and electric submersible pump optimisation. Silixa has developed a range of advanced embedded data handling and visualisation tools to process the high volume of data generated by iDAS.
