A downhole pulsing-shock reach extender method for overcoming static friction resistance in coiled-tubing drilling-fluid-pressure driven downhole operations, by generating pulsed hydraulic shocks at the workstring by creating a fluid-hammer condition by repeated sudden opening and closing of a valve controlling a diverted portion of the flow of drilling fluid, while maintaining a constant flow of a portion of drilling fluid sufficient to operate and prevent damage to other components of the workstring, thereby extending the depth limit of downhole operations.
