Improvements in the Seismic Profiler
The Journal of the Acoustical Society of America, 1964Three improvements in the continuous seismic profiling system used by the Geophysics Department of the Woods Hole Oceanographic Institution are the use of (1) an electrical-spark sound source of 100 000 J maximum stored energy, which can produce a variety of acoustic pulses with peak pressures of up to 134 dB above 1 dyn/cm2, at a repetition period of ...

Borehole seismic profiles in the ekofisk field
SEG Technical Program Expanded Abstracts 1984, 1984Abstract In October 1983 a major borehole seismic survey was carried out in the Ekofisk oil field in the Norwegian sector of the North Sea on behalf of the Phillips Petroleum Licence 018 group of companies. A vertical seismic profile with the source vertically above the geophone in the highly deviated wellbore and three multilevel ...

The use of vertical seismic profiles in seismic investigations of the Earth
Geophysics, 1982Abstract During the past 8 years, the U.S. Geological Survey has conducted an extensive investigation on the use of vertical seismic profiles (VSP) in a variety of seismic exploration applications. Seismic sources used were surface air guns, vibrators, explosives, marine air guns, and downhole air guns. Source offsets have ranged from

The Journal of the Acoustical Society of America, 1987
In vertical seismic profiling (VSP), VSP seismic data is transformed into surface seismic data by mapping segments of the VSP seismic data into surface seismic data time. The transformation results in data which is more easily interpreted with respect to determining subsurface structure because the data is stacked and because the data is in a more ...

The Leading Edge, 1985
Vertical seismic profiling is one of the rapidly developing areas of geophysical technology for exploring in mature basins. The measurement basically involves recording the total upgoing and downgoing seismic wave fields propagating through a stratigraphic section by means of geophones clamped to the wall of a drilled well.

Improvements in the continuous seismic profiler
Geophysics, 1965Abstract The continuous seismic profiling system used at the Woods Hole Oceanographic Institution now has (1) an electrical spark sound source which has a maximum stored energy of 100,000 joules and can produce a variety of acoustic pulses with peak pressures of up to 134 db above 1 dyne/cm 2 , at a repetition period of 10 sec, and ...

Seismic profiling the continental lithosphere
Nature, 1985Deep seismic-reflection profiling is successfully being used worldwide to study the structure of the continental crust1–7. The MOIST8 profile recorded by BIRPS (British Institutions Reflection Profiling Syndicate) was the first to show that the structure of the upper mantle could also be imaged given a powerful source and long recording times.

Marine Vertical Seismic Profiling
Offshore Technology Conference, 1983ABSTRACT Limitations in sonic and density logs and marine COP data produce ambiguities in analysis and interpretation of this information for exploration prospect evaluation and production reservoir delineation. Marine vertical seismic profiling (VSP) provides an added tool to help unravel many of these ambiguities ...

A seismic profile in southern Norway
pure and applied geophysics, 1980Data from a reversed seismic crustal profile crossing the Caledonides of southern Norway suggest a continuously increasing P-wave velocity followed by a low-velocity zone extending from a depth of about 14 km downwards. Interpretation of observed travel time and amplitude characteristics leads to a thickness of 4 km and velocity of 6.0 km/s for this ...
