Abstract
A remotely-operated selective fracing system and valve. The valve comprises a casing with at least one casing hole; an inner sleeve nested within the casing and having at least one sleeve hole alignable with the at least one casing hole; actuator means engagable with the inner sleeve for moving the inner sleeve relative to the casing to selectively align the at least one sleeve hole with the at least one casing hole; and receiver means electrically connected to the actuator means and having a sensor for detecting a seismic or electromagnetic signal generated by a remote source. The system further includes source means for generating an acoustical signal receivable by the receiver means.
