متن کاملIn Situ Measurement of Electroosmotic Fluxes and Conductivity Using Single Well Bore Tracer Tests
Electroosmosis (EO), the movement of water through porous media in response to an electric field, offers a means for extracting contaminated groundwater from fine-grained sediments such as clays that are not easily amenable to conventional pump-and-treat approaches. The EO-induced water flux is proportional to the voltage gradient in a manner analogous to the flux dependence on the hydraulic gr...
متن کاملRescue Robotics in Bore well Environment
A technique for rescue task in bore well environment has been proposed. India is facing a distressed cruel situation where in the previous years a number of child deaths have been reported falling in the bore well. As the diameter of the bore well is quiet narrow for any adult person and the lights goes dark inside it, the rescue task in those situations is a challenging task. Here we are propo...
متن کاملWell bore boundary conditions for variably saturated ̄ow modeling
Well bore boundary conditions are incorporated in a three-dimensional ®nite element model that solves the variably saturated groundwater ̄ow equation. One-dimensional line elements, which are used to discretize the ̄ow equation along the well screen, are superimposed onto three-dimensional porous media elements. The use of line elements allows the inclusion of well bore storage eects, and also...
متن کاملThe Effect of Fault Plane on the Horizontal In Situ Stresses Orientation: a Case Study in one of Iranian Oilfield
Knowledge of the orientation of horizontal in situ stresses is important to some areas of oil and gas field development plans. Borehole breakouts observed in image logs and drilling-induced fractures are the main parameters for the determination of the stresses’ directions in situ. In this work, the orientations of borehole breakouts were investigated as a function of depth in oil wells A and ...
