Electric Logging (ELOG)
الخيارات الثنائية بنجاح يراز مئير The Elog is the classic water-well combination probe combining shallow, medium and deep penetrating resistivity measurements with self-potential (SP).
Principle of Measurement:
كيف استطيع تداول الاسهم داخل الامارات A low-frequency bi-directional electric current from a source electrode on the probe returns through the formation to the cable armour above an insulated bridle. Potentials due to this current flow are measured on various sense electrodes on the probe with respect to a voltage reference ‘fish’ normally located at the surface. These measurements are converted to apparent formation resistivities within the probe and digitally transmitted to the surface.
