Seismoelectric monitoring of producing oilfields: A review.

摘要: Seismoelectric phenomena associated with seismic waves and activities have been observed in the laboratory field for several decades. Geophysical techniques using active sources such as reflection can be modified to adapt requirements seismoelectric surveys observations. Electrokinetic potential is a candidate mechanism explain artificial sources. Coupled electrokinetic signals are at surface or borehole grounded dipole antennas. Efficient power-line telluric noise (using remote-referencing) reduction essential improve weak amplitude of signals. Preamplifier analog notch filtering valuable tools this regard. Properties pore fluids solid matrix estimated linear relationship between its accompanying waveforms, which make technique possible tool characterization porous media. Simultaneous multi-component recording will key contribution estimate rock fluid properties interest. The delay traveltime concept generated by positive holes makes it plausible monitoring seismically environments undergoing natural induced microfracturing producing oilfields. A processed pilot study an array pairs dipoles over area should able evaluate ability process.
