Join the Fiber-Optic Distributed Acoustic Sensor (DAS) for Geophysical and Industrial Applications session to learn about the use of DAS for novel geophysical or industrial applications at AGU in New Orleans, Louisiana on 13 December 2017.
Distributed acoustic sensing provides a flexible and large sensing aperture for acquiring high resolution acoustic data in time and space. The use of DAS in the industry for flow profiling, high resolution borehole/surface seismic imaging, micro-seismic monitoring for fractures has been accelerated with the improvements in the sensitivity, the advances in real-time big data processing and flexible deployment of fibre optic sensing cables.
There is a growing interest in the use of DAS for critical geophysical infrastructure applications such as earthquake and near-surface passive seismic analysis including the development of tailored or new numerical techniques.
Silixa’s oral presentation is titled High Definition Seismic and Microseismic Data Acquisition Using Distributed and Engineered Fiber Optic Acoustic Sensors, and will be presented on 13 December 2017 at 15:12 pm.
Over the past few years Silixa has successfully used DAS to record microseismic events during hydraulic fracturing and re-fracking operations. Detection has been successful in a number of configurations, where the fibre has been in a horizontal treatment well, horizontal well adjacent to the treatment, or vertical observation well. We will discuss the sensitivity of the measurement, range of measurement, ability to localise the events and characteristics of the microseismic event. In addition to discussing the theory we will also present case studies showing the detection and localisation and how these compare to conventional microseismic detection techniques.
