Hunter's comment

Silixa’s intelligent Distributed Acoustic Sensor (iDAS) is an optoelectronic system which records the true acoustic signal continuously along the path of sensing fibre tens of kilometres long.

This is an emerging technology in the field of borehole geophysics and serves long pending demand to E&P industry for on demand cost efficient borehole seismic measurements. Although it solves the problem at receiver end for broadband borehole seismic acquisition but it still remain limited due to sources being band limited. However, other advantages like on demand seismic remains major advantage of the technology for real time and permanent monitoring.

iDAS collects the true acoustic signal – amplitude, frequency and phase – at all points along an optical fibre. This breakthrough capability uniquely allows the iDAS to determine the speed of sound in the material surrounding the sensing cable; hence opening the door to a wide range of applications, such as flow quantification.
