Abstract: A capacitive cable, as well as a method for operating a downhole electro-hydraulic (EH) tool using the capacitive cable, are described herein. The capacitive cable includes at least one standard conductor and at least one capacitive conductor including integrated wire-shaped capacitors. The method includes inserting a tool string including the capacitive cable and an attached downhole EH tool into a wellbore and conducting power from the surface to the downhole EH tool via the standard conductor(s) of the capacitive cable. The method also includes storing electrical energy downhole within the capacitive conductor(s) of the capacitive cable, and activating the downhole EH tool to provide for the rapid release of the electrical energy from the capacitive conductor(s) into the downhole EH tool, initiating an electro-hydraulic event within the wellbore.

Abstract: Hydrocarbon wells and methods of probing a subsurface region of the hydrocarbon wells. The hydrocarbon wells include a wellbore, a downhole sensor storage structure, and a detection structure. The wellbore may extend within a subsurface region and between a surface region and a downhole end region. The downhole sensor storage structure is configured to release a flowable sensor into a wellbore fluid that extends within the wellbore, and the flowable sensor may be configured to collect sensor data indicative of at least one property of the subsurface region. The detection structure may be configured to query the flowable sensor to determine the at least one property of the subsurface region. The methods include releasing a flowable sensor, collecting sensor data with the flowable sensor, and querying the flowable sensor.
