Show geophysics helps in oil search of relatively recent intensive e use he the science of geophysics has become of age in the for petroleum um by the use of this new means s scientists c are able to map the underlying nd eulying structures that might lie ile thousands of feet below the sur surface I 1 ace of the earth through the use of electronic devices that record shock waves so new is this science and so profound that few schools of higher learning offer a degree degre in this study one of these is the colorado school of mines in golden colo basically the geophysical crew or seismic crew as they are often called go into an area and bivey stavey particular spots for their research A hole bole is drilled and a charge of explosives is lowered into the bole hole at a given signal the explosive is set off and the hock shock waves penetrate the underlying formation formations some at these formations offer resistance to the shock wave and are reflected upward toward the surface of the earth these waves are picked up by the sensitive receivers and are am relayed to the central truck of the crew here an all of the vibrations from all of the receivers are correlated into a single machine and these waves are recorded oa on long strips of paper this Is only the beginning once the data is gathered it ft remains for another versed in this technical study to further correlate this maze of seemingly un intangible waves into the reality of what exists under the surface of the earth once this is done the compiled data Is passed on to others in the company for consideration of its possibilities as a site for I 1 the drilling of oil |
