Exploring the link between the flow zone indicator and key open-hole log measurements: an application of dimensional analysis

摘要

Dimensional analysis has been used as a tool for developing a non-linear empirical model giving the flow zone indicator (FZI) as a function of open-hole log measurements. Dimensional analysis confirms that interval transit time (Delta(t)), true resistivity (R-t), bulk density (rho(b)), the apparent water resistivity (R-wa) and the photo-electric absorption (P-e) are essential well-log measurements for estimating the FZI in sandstone formations.
