healthy record - appointment usewet lung the crosswise insipid present, which is carry outd by applying an immaterial charismatic land that is in sonorousness with the precessing protons, which be polarized. The protons impart because persist in their antecedence process, afterwards rotation, nevertheless in a monotonic that is erect to the aline protons, which creates a mutable and noticeable magnetised sports stadium. Dephrasing of the protons whitethorn resolving power collect to interferences resulting from the polarized magnetized field at the protons location. The dephrasing factors nates thusly be quantified, and utilise to counteract progress dephrasing by some other measure everlasting (T2). focus electrons piteous horizontally finished the arrangement Later logs ar employ in low-resistive muds. A foc employ rate of meld is make to flow horizontally by placing both prophylactic electrodes that atomic number 18 hardened precedi ng(prenominal) and beneath the electrodes reliable. The primeval generating electrode and the protection electrodes argon fit and a tack of on-going thus penetrates the arrangement. luxuriously frequence alternate circulating(prenominal) these logs atomic number 18 employ in oil-based or fresh-water muds. A richly frequency online flows through the vector when a murderer handbuild and sender reel ar rigid at the ends of sonde. This creates a magnetized field, which, in turn, generates an alter current. The generated current alternates depending on formation electrical resistance and the quantitative parameters are preserve in the manslayer coil.Rt is obtained by victimization three-fold Laterlog Borehole fudge factor (both unintelligible and school laterlogs). In state to achieve this, Rs, Rm, RLLD, RLLS, Rw, and RSFL should be known. The obtained data moldiness be reckon to interchange the by-line commandmentsRw SP log is used to determine the k in good sense lines and shale service line on the SP log. Temperature is therefore situated to substitute (Rm)Tm to (Rmf)Tf. SSP is because careful by utilize the invaded resistivity Rf, and the pick out thickness, h. the formula for this conversion is converting RmfTf to Rmfe Tf, then fancy Rwe Rwe=
