Abstract

The principal aim here is show a transient thermal-resistivity log dependence. The induction devices (ILM and<br>6ff40), common used in log interpretation, may have some errors and new corrections will be needed. This<br>features are presented when multilayer transient temperature is evaluated and applied to resistivity model. A<br>simple eight meters deep formation is simulated with 2d-thermal and resistivity model, composed by shale and<br>sandstone reservoir, where multiphase radial fluid flow was performed. Due mud circulation, temperature<br>dependence of apparent resistivity formation are evaluated and compared with the resistivity when wellformation<br>temperatures are the same (150oC). Errors into 1% to 12% are expected to medium and deep induction<br>log information with this model.
