Abstract
Geophysics is adding technology which can pinpoint drill sites, quicken drilling schedules and enhance success ratios. The use of 3-D seismic surveys can help determine the exact extent and shape of an oil or gas field. Vertical seismic profiling (VSP) also is proving to be extremely useful among companies that recognize its potential. A land air gun has started to refine the seismic surveys since it can be refired on 6 to 8 second intervals. A combination of these geophysical techniques may become a cheaper and more effective way of correlating strata.
