Cementation Exponent m. Function and Calibration - Petrophysics Courses & Training
The goal of m It is to convert The log evaluation's o and a*Rw ? In the log evaluation's estimation of Ro (Water saturated formation resistanceivity), not core analysis version Ro Or the "true" Ro. This log analysis is used to determine the reservoir saturation. m It is an internal log analysis parameter. It fails to produce Ro It is not suitable for use and is incorrect in the real world. Because the laboratory scale is cm, the scale of the Rt logged, which it will be used with, is metre, or possibly dm, the laboratory is not a good analogy for in-situ conditions. Log analysis "equations” assume that inputs came from the same piece, but they may not have if the inputs are different. SCAL is a perfect example of this. m Logging Rt In heterolithic facies. Certain water zones (Sw100 from side-walls cuttings and the chromatograph) span a range O in rocks of similar rock types (similar O-k Crossplots). We have access to log data's actual Ro and...
