An introduction to seismic reflection data: acquisition
The Society of Exploration Geophysicists (SEG) (Thigpen et al., 1975) defines the two types of polarity convention used for displaying seismic data using minimum-phase or zero-phase wavelets as either 'positive standard polarity' (American polarity) or 'negative standard polarity' (European Polarity) (Fig. 22.3).
A Handbook for Seismic Data Acquisition in Exploration
Thus, the seismic exploration industry was born, and the seismologists working in that industry came to be called exploration geo-physicists. Today seismic exploration encompasses more than just the search for resources. Seismic technology is used in the search for waste-disposal sites, in determining the stability of the ground …

1. Seismic Exploration | A Handbook for Seismic Data …
The underlying concept of seismic exploration is simple. Man-made seismic waves are just sound waves (also called acoustic waves) with frequencies typically ranging from about 5 Hz to just over 100 Hz. (The lowest sound frequency audible to the human ear is about 30 Hz.) As these sound waves leave the seismic source and travel downward into the ...
Seismic methods in mineral exploration and mine planning
Seismic methods provide high-resolution images of geologic structures hosting mineral deposits and, in a few cases, can be used for direct targeting of mineral deposits. Applications are not limited to only surface seismic surveys, but also include borehole seismic methods such as VSP and crosshole imaging. To date, tens of 2D and 3D …
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.

Seismic Survey
Seismic surveys are conducted by deploying an array of energy sources and an array of sensors or receivers in an area of interest. Figure 3.9 shows a seismic survey on land. The source of seismic waves is either an explosive which directly generates the seismic wavelet or a mechanical source which is commonly a vibrator, which uses a steel base plate in …
Cost-Effective Seismic Exploration: 2D Reflection Imaging at …
We show that by using an advanced pre-stack depth imaging algorithm it is possible to retrieve meaningful and robust seismic images with sparse shot points, using only 3–4 source points per kilometer along a seismic profile. Our results encourage the use of 2D seismic reflection profiling as a reconnaissance tool for mineral exploration in …
