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.

The oil and gas industry has extensively relied on seismic exploration technology, demonstrating nearly a century of global usage that attests to its reliability.

During an earthquake, released energy manifests as seismic shock waves, inducing Earth vibrations—aptly named seismic waves.

What are the relations between seismometer and geophone?   Microtremor is a kind of weak vibration generated by nature or human activities, with an amplitude of only a few microns to dozens of microns, which can be observed on seismometers.   What is Microtremor Survey?   Microtremor survey is a detection method that collects micromotion […]

What is a MASW?   MASW is a shortcut of Multichannel Analysis of Surface Waves. The MASW method deals with surface waves in the lower frequencies(e.g.,1-30Hz) and uses a much shallower depth range of investigation ranges from a few meters to a few tens of meters. MASW deals with relatively lower frequencies and shallower investigation […]

How to use seismic methods?   When you have a need for non-destructive investigation technique for subsurface conditions, seismic methods can be a good alternative to provide a more comprehensive image compared to traditional intrusive methods such as digging and drilling. Seismic methods record the movement of vibrations through the round with their speed and […]

Geophones are used in seismic investigations to transform the vibration in the ground into a voltage. The geophones are analogue sensors, with a spring-mounted wire coil moving past a magnet. This creates the electrical signal with is recorded by a seismograph such as the ABEM Terraloc, PASI GEA 24, Geode 24 or DAQ Link 3 […]

  What is electrical resistivity?   Electrical resistivity sends an electrical current into the ground and maps the resistance against that flow of the current. The resistance can be converted to resistivity, a property used to predict the composition, structure or strength of the underlying materials. As we all know, different geological materials present different […]
