Show RADIO AND DYNAMITE USED LOCATING OIL radio to the average person means entertainment to the oil man it means the possibility of finding oil in the last 3 or 4 years geophysical instruments have played a prominent part in locating oil pools in the rocky mountain region right at the present time they are being made use of by major oil and gas producing companies in several states in the and especially in wyoming so successful has the radio been in locating oil pools that the federal radio commission has allocated to oil companies frequencies in the continental tin short wave band for geophysical purposes pur poss the transmitters are portable with a power range of 10 to 50 watts making it possible to meet all atmospheric conditions radio in locating oil pools is used in combination with dynamite explosions in the area being explored a radio signal is emitted simultaneously with the explosion of a charge of dynamite the radio signal setting in motion radio waves and the dynamite sound waves by measuring the elapsed time it takes the radio wave to travel from point to point and comparing it with the time taken tor the travel of the sound through the earth crust scientists are able to determine where there should be a deposit of oil oil is it poor electrical conductor and the presence of any great quantity naturally tends to retard progress of the radio wave particularly is this true in areas where salt domes exist the salt dome is said to be detected invariably through the use of me radio process and salt domes frequently although not invariably bespeak the presence of oil |
