Distributed Acoustic Sensing (DAS)

High-resolution reservoir and flow analysis

DAS technology measures vibrations, enabling detection of seismic events and small flow changes that are difficult to capture with conventional distributed temperature sensing (DTS) technology. The DAS data helps to calibrate inflow profiling and can distinguish, for example, gas or solids (sand) from liquid flow.

Borehole Seismic

Wireline-conveyed tools and systems for high-resolution seismic images in and beyond the borehole.

3D VSP Processing

Perform 3D surveys in the borehole with 3D vertical seismic profile (VSP) technology.

Distributed Acoustic Sensing Technology

Make every logging run and fiber installation an opportunity for borehole seismic acquisition in minutes.

Microseismic Services

Record microseismic activity in real time during the fracturing process.

Borehole Seismic Surveys in Minutes, not Hours

VSP data collected using single- and multimode optical fibers.
By using any optical-fiber cable deployed or installed in a well, distributed acoustic sensing (DAS) uses only minimal equipment at surface and doesn't require running tools. Visit Distributed Acoustic Sensing page
