Abstract
During a surge-pulsing operation in a borehole (e.g an oil-well undergoing remediation) liquid is stored under pressure upstream of a valve, and then released through the valve suddenly enough to create a seismic wave, which propagates into the formation around the borehole, and assists the surge-pulsing to improve the conductivity and liquid-injectability of the formation. The downhole valve achieves the rapid-opening requirement by virtue of its geometrical layout, as dictated by the strictures of the downhole environment.
