Multiple Regression and Modified Faust Equation on Well Logging Data in Application to Seismic Procedures: Polish Outer Carpathians Case Study

An appropriate velocity model from well logs is a key issue in the processing and interpretation of seismic data. In deep borehole located central part Polish Outer Carpathians, sonic measurements were inadequate for purposes due to poor quality data gaps logging. Multiple regression (MR) modified Faust equation proposed log. MR estimated P-wave slowness as dependent variable on basis sets various independent variables. The solutions verified by interval Check Shots (CS) convergence synthetic seismograms real traces. proved be an effective method when set other was available. allowed computation based shallow resistivity logs, depth, compaction factor. coefficients determined according lithology stratigraphy divisions calibrated with use previously analysis. may applied nearby old wells limited logging data, particularly no where could not successfully applied.
