    We investigate a new algorithm for computing regularized solutions of the two-dimensional magnetotelluric inverse problem. The algorithm employs a nonlinear conjugate gradients (NLCG) scheme to minimize an objective ...
  • Hu, Hengshan; Wang, Kexie; Wang, Jingnong (Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)
    When an acoustic point source located on the borehole axis emits an acoustic wave, an electric field, as well as an acoustic field, is generated in the porous formation around the borehole due to an electrokinetic effect. ...

    The objective of tills study is to discriminate between aeolian and fluvial deposits of the Permian Unayzah formation in Central Saudi Arabia by using wireline logs. The analysis is conducted on wire-line logs (field ...
  • Edie, Margaret S.; Olson, John F.; Burns, Daniel R.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)
    Realistic simulations of flow in porous media are dependent upon having a three-dimensional, high resolution image of pore structure which is difficult to obtain. So, we ask the question, "How fine a resolution is necessary ...

    We show both theoretically and experimentally how stress concentrations affect the velocity field around a borehole surrounded by a formation with intrinsic ortohombic anisotropy. When F[subscript x] = F[subscript y], ...
