SUMMARY:The low-frequency acoustics of drilling a borehole - Ben Jeffryes\

DESCRIPTION:A borehole\, and the drillstring used to drill it\, are long a
 nd thin\, and so at low frequencies their acoustic behaviour is well descr
 ibed by one-dimensional equations.  Despite the apparent simplicity of the
  equations\, they exhibit a range of interesting behaviour\, such as acous
 tic localization\, radiation tunnelling and resonances with strong mean fl
 ow-rate dependence – all of which have practical implications.\n\nIn thi
 s talk I shall describe some of the practicalities of deep drilling\, befo
 re showing how these acoustic phenomena arise.
