    • Experimental Studies Of Seismoelectric Measurements In A Borehole 

      Zhu, Zhenya; Haartsen, Matthijs W.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)
      Experimental and theoretical studies show that there are two kinds of electromagnetic (EM) fields generated by seismic waves in a fluid-saturated porous medium. First, at an interface where the formation properties are ...

    • Experimental Studies Of Electroseismic Conversion In A Fluid-Saturated Porous Medium 

      Zhu, Zhenya; Haartsen, Matthijs W.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)
      The coupling between seismic and electromagnetic waves in a fluid-saturated porous medium is essentially controlled by the electrokinetic effect. The inverse effect of the seismoelectric conversion, the electroseismic ...

    • Using Borehole Electroseismic Measurements To Detect And Characterize Fractured (Permeable) Zones 

      Mikhailov, Oleg V.; Queen, John H.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)
      We present a new type of field measurement capable of detecting and characterizing fractured (permeable) zones intersecting a borehole. The method is based on measuring electrical fields generated by a borehole Stoneley ...
