The Basics of Distributed Acoustic Sensing

Posted on Jun 26 2019 - 7:58am by Editor

There are many ways of sensing information and one of the most effective continues to be through detecting and analyzing sound waves. With distributed acoustic sensing, a fiber optic cord is sheathed in an acoustic sensing housing that can pick up sounds along the length of the cord. This allows for a more detailed scan of dangerous, hazardous or hard-to-reach places. It can also detect the strain that the cord itself is under to help prevent breaks.

Distributed Acoustic Sensing

How It Is Used

One of the ways that distributed acoustic sensing (DAS) is used is to sense disturbances around fracking operations underground. This can be before, during and after fracking operations to ensure the safety of the process, the personnel and the equipment. It can also be used to help guide the fracking operation to the right underground deposits.

Where It Is Used

DAS is usually used underground to create less disturbance to sites used for oil drilling and fracking. It can also be used to measure seismic events and monitor fault lines with less of an equipment footprint and impact on the surrounding area.

Distributed acoustic sensing is a good way to see what is going on in difficult to reach or dangerous places. This is widely used in oil drilling and fracking operations before, during and after the process. It can be used to find the right deposits to extract, to monitor the health of your equipment during the operations and even to see the seismic effect after the process.
