Multimin solves interpretation problems in reservoirs of complex lithology containing variable amounts of clay. It uses CORIBAND type logic to solve porosity, Sw, Sxo, and mineralogy in an iterative residual hydrocarbon corrections solution.

Available model selections include:

Neutron-Density
Neutron-Sonic
Neutron-Density-Sonic
Neutron-Density-Pef
Neutron-Density-Sonic-Pef

Other characteristics of PowerLog® MultiMineral Analysis / Complex Lithology include:

Mineral types and parameters for the 3- and 4-mineral models are user-specified.
You can compute water saturation from straight Archie, Indonesian, Simandoux or modified Simandoux.
Sxo, Srh are available from Rxo, EPT, or empirical relationship to Sw.
Sonic limit logic is available for bad hole zones.
Logic for coal, salt and oil base mud is included.
