Abstract
Abstract A method of stimulation oil well production uses a gas generating chemical charge that is placed in the oil well bore at a depth of known oil productivity where it is ignited to generate a gas pressure-volume pulse of known pressure-time characteristics and time duration, the pressure time characteristics includes a pulsating pressure for greater penetration effect.

Claim 1
Independent Claim
109 words
The process for stimulating the flow of oil in an oil well comprising the steps of creating in the bore of said well at a strata of known oil production, a first gas pressure-volume pulse comprising a plurality of overlapping gas pressure-volume pulses of approximately equal magnitude, sequentially propagating up the longitudinal axis of said bore, creating simultaneously in the bore of said well and spaced apart from and above said first gas pressure-volume pulse, a second pressure-volume pulse comprising a plurality of overlapping pressure-volume pulses of approximately equal magnitude and approximately equal in characteristics to said first pressure-volume pulse, sequentially propagating down the longitudinal axis of said bore.
