ABSTRACT:
The electromagnetically accelerated impact oil well drill uses magnetic interaction of a ringing circuit formed in each of multiple accelerating coils with the electromagnetic field of charge rings around an expendable ice filled plastic drill head to accelerate the drillhead to hypervelocity with the drill head properly aligned to shoot down through an upper installed oil well casing. The oil well casing being fitted with a rapidly operating diverter valve to deflect effluent from the casing from blowing back into the electromagnetically accelerated impact drill.
