1. Applied Geophysics: Seismic Prospecting Methods INTRODUCTION Method Geophysical Parameter Geological Information Seismic travel time from layer boundaries, source to geophone; density, porosity compute wave velocity Seismology makes use of the travel times and velocities of seismic waves (also earthquake waves) to study the nature of the interior of …
Seismic techniques have had relatively limited utilization, due to their relatively high cost and the difficulty of acquiring and interpreting seismic data in strongly faulted and altered igneous terranes, in mineral assessments and exploration at the deposit scale. However, shallow seismic surveys employ less expensive sources and smaller

Abstract. BOTH from an academic and a commercial point of view, the exploration of the crust of the earth by explosion waves has assumed considerable importance in recent years. Of great ...
An account of the mathematical properties of velocity functions used in the seismic method of geophysical prospecting is presented. Basic equations are given for deriving various quantities of interest associated with a particular velocity function, such as average velocity as a function of depth, average velocity as a function of vertical travel time, parametric equations for …
(PDF) Overview of high resolution seismic . To calibrate the seismic results, some boreholes were cored within the seismic lines.The aims of this paper are twofold:-firstly, to discuss the different tests made in the framework of the experiments in order to minimize the environmental impact and the costs and to optimize the acquisition techniques for shallow …
Publication date: January 01, 1967. The seismic method is divided into reflection and refraction techniques, based on whether or not a wave undergoes a reflection at the extent of its travel. Thus, while most refracted events have not been reflected, most reflected events have been refracted, because a refraction occurs across any velocity ...
6.2.1.3 Applications. An aeromagnetic survey is a kind of geophysical prospecting, which makes use of airborne geophysical surveying gauges installed in an aircraft at a certain flight height range to acquire magnetic field strength from the subsurface. In 50 years of airborne geophysical surveys in China, the aeromagnetic survey, one of the ...
Definition of seismic prospecting. A method of geophysical prospecting in which vibrations are set up by firing small explosive charges in the ground or by other artificial sources. Precise measurements of the resulting waves are taken, from which the nature and extent of underlying strata are revealed. Ref: Hammond.

Seismic prospecting is conducted either on land or at sea. Seismic waves are generated by chemical explosions or vibrating impacts of short duration. By recording the time history of the reflected seismic waves, information on the nature and geological significance of the Earth's interior can be obtained.
The topics that will be discussed cover a wide spectrum and are representative for what has become feasible nowadays. Who should attend: Geophysicists processing and interpretation- who are actively involved in advanced or special seismic processing, e.g. as a member of a multi-disciplinary team. Content of the program:

Abstract. We have seen from the previous discussion that a medium having anomalous structural features affects both velocity and direction of a propagating seismic wave. Observation of such effects is the essence of seismic prospecting. In fact all types of waves (reflected, refracted, and direct) have been employed in this type of investigation.
