The purpose of this report is to investigate methods to correlate petrophysical properties of the Ferron Sandstone, Utah. Properties investigated are the single phase properties of porosity, permeability, and formation resistivity factor. The purpose of the correlation is to be able to find a value of one parameter if the other two are known.

Previous models that relate two properties such as permeability-porosity models, permeability-formation factor models, and formation factor-porosity models are used to develop this correlation. A model from Hazlett (1989) which relates all three parameters is also applied to make a comparison and give a suggestion for developing a more general correlation.

The non-linear model developed using Quasi-Newton minimization method satisfies the raw data from Ferron. However, further investigation using more exhaustive data sets from various reservoirs is suggested to examine its generality.
