description | The presence of conductive minerals in sandstone reservoir will probably influence the reservoir resistivity
(Rt) response. Significant decrease of Rt, which is read by
log data will also cause misinterpretation. Such situation
is known as Low Resistivity Zone (LRZ) and need to be
solved using certain approach to determine the corrected
water saturation or Sw.
The research was conducted by laboratory
measurements of some sandstone pseudo cores, were
conditioned to have some hematite volume. Rt is
calculated from I (current in ampere) and V (voltage in volt) of the cores. Conductive mineral volumes (hematite)
and Rt values are graphically plotted for each Sw lines.
Result from laboratory measurements shows the
relationship between hematite and Rt for each Sw level were nonlinear (exponential) regression. Rt will decrease significantly at core samples with hematite contain of >2%. Each Sw levels provide different profiles, means that water saturation also influence the Rt response. Plot for hematite volume, Rt and Sw lines is a simple proposed method that can be used to estimate the corrected Sw. |
