<p>A method for providing for stimulating a subterranean target material (620) comprises: transmitting an inspection signal (615) comprising a plurality of frequencies to a subterranean target material; receiving a stimulated signal (627) in response to transmitting of the inspection signal, the stimulated signal indicative of at least one excitable frequency of the target material; analysing the stimulated signal to identify at least one excitable frequency of the target material so as to provide for stimulating of the target material, and transmitting an excitation signal (645) to the target material for stimulation. The target material may be material ahead of a drill bit, or may be material at a contact location between tubing and a drill string.</p> |
