Abstract
P333 Static and Dynamic Young’s Modulus of Marly Chalk from the North Sea Introduction 1 Deformation properties of a rock are governing factors for production of oil from a reservoir. These properties can be either determined from geotechnical consolidation testing (also called static tests) or from acoustic data (dynamic tests). The main differences between the two tests lie in the frequency of the measurements and the strain amplitude used in the tests. When a sound wave propagates through a porous medium the deformation of the grains is elastic. In a geotechnical test the strain is larger and a non-elastic deformation
