Frequently Asked Questions

Hydrophone sensitivity measures its ability to detect weak underwater sounds, expressed in volts per microPascal (V/µPa). It is crucial for applications such as marine biology, sonar systems, and seismic research.

Learn how MEMS piezoelectric hydrophones are revolutionizing underwater sensing with their high sensitivity, compact size, and versatile applications in marine biology, seismic monitoring, and underwater communication.

Compare MASW and downhole seismic testing for subsurface investigations, focusing on methods, applications, and advantages.

Seismic reflection and seismic refraction are two primary seismic methods used to explore the Earth’s subsurface, especially in the petroleum industry.

Seismic Tomography provides high-resolution 2D or 3D images of seismic velocities between boreholes. The method is used to delineate geological structures, to map cavities and weak zones and to specify mechanical soil and rock properties.

Spurious frequency is usually specified by manufacturers, but users often know little about it. So, what is spurious frequency, and how does it affect seismic data?

The geophones can be deployed on the surface or near geothermal reservoirs in wells to gather detailed data.

In the realm of seismic monitoring and exploration, two indispensable instruments take center stage: accelerometers and geophones.

At the heart of this technique lies apparent resistivity, a pivotal parameter offering essential insights into the makeup and configuration of subsurface layers.
