Abstract

The problem of solving for the fraction of sylvite, car- nallite, halite and insoluble material in the Prairie Eva- porite formation can be performed by a suitable inter- pretation program based on Gamma Ray, Sonic, Neutron and Caliper logs. Empirical relations were established between the log values and the formation parameters, the result being a set of four simultaneous equations which may be reduced to obtain the desired fractions. Tedious hand calculation can be eliminated by using computer techniques and automatic log digitizing machines. Correla- tion between core and log analysis is good, and the speed and efficiency of the method is valuable in initial forma- tion studies.
