What is a Seismic Geophone?

What is a Seismic Geophone?

Seismic geophone is a device used in surface seismic acquisition, both onshore and on the seabed offshore, which detects ground velocity produced by seismic waves and transforms the movement into electrical impulses. Geophones detect motion in only one direction. Conventional seismic surveys on land use one geophone per receiver location to detect motion in the vertical […]

What is a Seismic Land Streamer?

What is a Seismic Land Streamer?

A seismic land streamer is an array of geophones designed to be towed along with the ground. It is a receiver array specially designed for land seismic surveys. A land streamer is suitable for MASW, refraction, reflection and surface-wave surveys which make the field survey easier and higher productivity without compromising data quality. Why it […]

What’s the difference on OBC and OBN Seismic Exploration?

What’s the difference on OBC and OBN Seismic Exploration?

At present all countries have shifted the focus of oil and gas exploration to Ocean. As the main means of oil exploration in shallow sea areas, OBC (Ocean Bottom Cable) seismic exploration and OBN(Ocean Bottom Node) seismic exploration have been rapidly promoted and applied in seismic exploration for shallow sea by relying their flexible layout […]

Is there any necessity to add some parameters of seismic geophone?

Is there any necessity to add some parameters of seismic geophone?

With the development of geophysical prospecting, especially to meet the needs of high-precision prospecting, high-density acquisition, broadband acquisition, single-point acquisition and low-cost acquisition. The parameters of seismic geophone data should be added to the parameters of the geophone, including but not limited to. Develop displacement geophones, add new performance indicators, perform some physical inspections on […]

What is Shallow Seismic Exploration?

What is Shallow Seismic Exploration?

Shallow seismic exploration is an engineering geological and geophysical exploration that uses the characteristics of seismic wave propagation in different rocks and soils to detect shallow geological structures (usually tens to hundreds of meters) and determine the physical and mechanical parameters of rock and soil. As per different tasks, purposes and different geological conditions, different […]

What is Schlumberger Array?

What is Schlumberger Array?

The Schlumberger array is an array where four electrodes are placed in a line around a common midpoint. The two outer electrodes, A and B, are current electrodes, and the two inner electrodes, M and N, are potential electrodes placed close together.   Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity […]
