Abstract

Summary

Accurate Estimation of shale volume is a necessary part of reservoir characterization. The proposed workflow demonstrates the usage of factor analysis and linear regression in estimating precise formation shaliness. Ground-water reserves trapped in shaly formations can also be accurately determined using this proposed workflow. Conventional techniques are selective in log data when evaluating formation shaliness but in our analysis all the well logs were considered and it was assumed that all the well log data contained a significantly weighted proportion of information pertaining to the volume of shale which makes our method more robust. Factor analysis using linear regression models gave an empirical relation in the estimation of formation shaliness which was unique for the given geological conditions. Inversion results were in good agreement with the proposed workflow within the experimental error limits.
