ABSTRACT:
Method and apparatus for pressurizing a reservoir comprising directly introducing gas into the reservoir from a first supply source in an amount to instantly pressurize the reservoir and balancing the pressure between a second supply source for service gas and the reservoir via a regulating valve mechanism which controls admission of gas under pressure from the second source into the reservoir when a differential exists between the second pressure source and the pressure prevailing in the reservoir due to its connection with the first pressure source.
