Standard interpretation (view source)
Revision as of 14:34, 16 January 2014
, 14:34, 16 January 2014→Water saturation in shaly reservoirs
* ''R''<sub>t</sub> = true formation resistivity
* ''R''<sub>t</sub> = true formation resistivity
* ''n'' = saturation exponent
* ''n'' = saturation exponent

The selection of parameters is similar to that described for clean reservoirs. Note that the equation is quadratic, making it significantly more difficult to solve manually for saturation. Normally, saturations in shaly sands are determined using computers or programmable calculators.
