Abstract:

The dire need to account for the in-situ wettability and their effects on the Electrical Properties measurements (m & n), mandated to come up with this refined technique to account for wettability effects accurately and efficiently.  

Ideally, “fresh-state” testing is preferred so as not to alter the rock fabric or change its wetting affinity. A key component of this technique, is to account accurately for the formation brine resistivity (R
w) that is saturating the "fresh-state” sample, which is often unknown particularly in reservoirs that do not produce water.  

R
wCoreTM on “fresh-state” core samples can provide precise formation brine resistivity (Rw).  This patented technique is independent of lithology, water saturation, and/or hydrocarbon saturation.

Initially, native resistivity (R
t) along with the formation brine resistivity (Rw) are determined on the “fresh-state” sample.  Additional (Rt) values can be established by further draining of the fresh-state samples.

At the conclusion of the electrical properties measurements; samples go through Dean Stark Residual Fluid Saturation analysis to provide material balance required for water saturation refinement that correspond to each of the fresh-state (R
t) points, basic properties will be measured after cleaning is done.  

Fresh-state “m”, “n” and “a” parameters will be derived using this technique, and in which they are needed for accurate log calibration and water saturation modelling.
