Open-ended seismic source

The Journal of the Acoustical Society of America, 1980
An open-ended seismic source for use in a liquid medium such as water is disclosed. The source includes a source of explosive gas, a firing chamber connected to the source, a capacitor discharge ignition system connected to the firing chamber for igniting the gas in the firing chamber, a barrel connected to the firing chamber, defining an explosion ...

GASBUGGY SEISMIC SOURCE MEASUREMENTS

GEOPHYSICS, 1972
Gasbuggy, a 29‐kt nuclear experiment, was detonated December 10, 1967, at a depth of 4240 ft in the San Juan Basin in New Mexico. Its purpose was to develop techniques for stimulation of natural gas production from tight gas‐bearing formations. Data from four subsurface instrument stations in a boring 1500 ft from Gasbuggy indicated formation of a ...

Seismic Source Regionalization

1987
Seismic source regionalization problem entails the full use of geologic, tectonic, historical, instrumental macro-seismic records, and micro-earthquake survey findings. The seismic sources are usually delineated on the basis of the uniformity of tectonic features, homogeneity of earthquake occurrences, and the consistency of focal mechanisms.

Downhole electromagnetic seismic source

The Journal of the Acoustical Society of America, 1988
A downhole seismic source (20) capable of generating seismic forces in excess of 1000 newtons. The source produces seismic waves for seismic applications, particularly cross borehole measurements and vertical seismic profiling. Coupled with motion sensing devices, the present invention also performs as a seismic logging tool. The source is comprised of

Dynamics of Seismic Sources

1981
The term dynamic source models usually refers to seismic source models based on fracture mechanics. We study in this paper the relation between the source rupture history and the far-field radiation on the basis of a few simple fracture models. A plane, two-dimensional crack model is used to show the main features of crack models and of the body waves ...
