Abstract:
1. A method for recovering hydrocarbon fluids from a subterranean formation penetrated by a well bore, the method comprising: introducing fracturing fluid through the well bore and into the formation to stimulate the recovery of the hydrocarbon fluids; fabricating at least a portion of a sealing tool from a material that breaks up when exposed to a detonated explosive; mounting an explosive on the tool; providing a valve on the tool; inserting the tool into the well bore and above the formation; activating the tool to establish a seal in the well bore above the formation; the valve allowing the recovered fluids to pass from the formation, through the tool and to the ground surface and preventing any fracturing fluid from passing into the formation after the tool is activated; and detonating the explosive to break up the tool.
