Abstract
A Stoneley wave propagating in a borehole generates pore fluid flow within the permeable
zones intersected by the borehole. In turn, the fluid flow induces a streaming
electrical potential. This electrical potential induced by the Stoneley wave can
be -measured in the field at frequencies from 100Hz to 4000Hz. Measurements of this
Stoneley-wave-induced electrical potential can be used to detect fractures and permeable
zones. The amplitude-versus-frequency dependence of this electroseismic phenomenon
provides a new way to test theories of the acoustics and the electrokinetics of porous
media against field measurements in real :oeks.
