the coupling of atmospheric compressions!, waves to various types of surface waves have been presented. Recently Benioff^ presented a paper describing a remarkable instance of sound waves received at Pasadena from the earthquake of 24 January 1951# 07-17-01, Magnitude 5.6, 33°07,N, 115°34,W, A=265 km. The microbarograph recorded a train of

1.1 Exploding Reflectors - Stanford University

The basic equipment for reflection seismic prospecting is a source for impulsive sound waves, a geophone (something like a microphone), and a mul- tichannel waveform display system. A survey line is defined along the earth's surface. It could be the path for a ship, in which case the receiver is …


Geophysical Prospecting - Florida Dep

Seismic Surveys – Reflection and refraction data of induced sound waves are the industry's primary tool for geologic modeling and drilling target selection. There are two basic types of seismic exploration: I. Explosive energy source: • Explosives (typically 1.1-5.5 lbs) are detonated at regular intervals in shallow boreholes (typically 100


Application Of Reflection Seismic Prospecting To Outlining ...

seismic prospecting we do not attempt to find oil directly but rather indirectly by outlining the structure and thereby deter­ ... the time required for a sound wave produced by an explosion to travel from a given point in the ground to another point, the sound waves in general taking a variety of paths in going from the first point to the ...


KGS--Petroleum: a primer for Kansas--Geophysical Exploration

Compressional waves, or P-waves, are the most common type of seismic wave used for reflection prospecting. P-waves propagating through the Earth behave similarly to sound waves propagating in air. P-waves generate echoes (reflections) when they come in contact with an acoustical contrast in the air or under the ground.


Offshore seismic prospecting method using a hydrophone ...

A method of seismic prospecting offshore by means of at least one pair of hydrophone-geophone sensors disposed at the water bottom, in which a sound source at the surface of the water emits a sound signal and the sensors at the water bottom take hydrophone and geophone recordings H and G, the method comprising the following various steps:


Reflecting method of seismic prospecting

Seismic prospecting can be done by two methods 1. Reflection method 2. Refraction method SEISMIC PROSPECTING 19/4/2013 4. 5. TYPES OF SEISMIC WAVES Seismic wave are classified in to the following 1. Compressional or Longitudinal or primary waves (P waves) 2. Shear or Transverse or secondary wave (S wave) 3.


Apparatus for seismic prospecting - Stotz, Charles C.

This invention relates to an apparatus for seismic prospecting, and particularly to an apparatus which visually records the sound wave reflected from various sub-surface strata and bodies. Since the amplitude of the recording needle or stylus is in proportion to the intensity, of the earth's...


Seismic Prospecting by the Method of Reflected Waves from ...

Relationship is established between some periods in the history of seismic prospecting and the changes in the understanding of its physical and geological foundations. Particular attention is given to the influence of the technological progress in seismic data processing on the change in the understanding of the structure and composition of a medium. Bibliography: 46 titles.


Method of exciting transverse waves in seismic prospecting ...

Nov 01, 1974· The method of transverse waves in seismic prospecting has a number of advantages in comparison with the method of longitudinal waves. Explosive methods of excitating transverse waves by which the directed effect of an explosion is created and used were tested. This wide testing of explosive sources became possible with the introduction of the method of selecting seismic waves according to …

Seismoelectrical Method | Environmental Geophysics | US EPA

As the seismic (P or compression) waves stress earth materials, four geophysical phenomenon occur: 1. The resistivity of the earth materials is modulated by the seismic wave; 2. Electrokinetic effects analogous to streaming potentials are created by the seismic wave; 3.


The Impact of Offshore Seismic Studies on the Marine ...

Seismic prospecting consists in the use of a specialized vessel, which will perform the following activities: - the emission of seismic waves by a seismic source, by producing an initial impulse (due to the violent expansion of a volume of compressed air), which will result in a series of pulsations of decreasing amplitude


Using seismic technologies in oil and gas exploration ...

Jun 12, 2013· These waves of energy move through the Earth, just as sound waves move through the air. In oil and gas exploration, seismic waves are sent deep into the Earth and allowed to bounce back.


Seismic Prospecting | SpringerLink

Abstract. Seismic prospecting has its basis in the classical physical principles of transmission, reflection, refraction, and scattering of elastic waves in a layered solid half-space. The great increase in application of the methods and the continual effort to improve them since 1925 have resulted in elaboration and refinement of instruments ...


Seismic Prospecting - an overview | ScienceDirect Topics

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.
