Correlation of Static and Dynamic Rock Mechanical Properties for Hydraulic Fracture Modeling

P. Rathi¹ and S. Sharma¹

Abstract

Log data such as density and sonic data from wells pertaining to single basin may be used to derive dynamic elastic constants such as compressive strength, Poisson’s ratio and elastic moduli for the formation rock. Additionally, static elastic constants may be determined through lab testing of core samples derived from the same set of wells; this predictably yields values differing typically by a factor of 1.5 - 2 from the dynamic constants.
