A METHOD OF TRANSFORMING RESERVOIR PROPERTIES TO A SEISMIC ATTRIBUTE FOR HYDROCARBON AND LITHOLOGY IDENTIFICATION

摘要

Embodiments of a method for transforming petrophysical properties into seismic attributes are disclosed herein. Embodiments of the method utilize an AVO expression which maps lithology to P-wave reflectivity at a particular angle through their ?/µ values (or equivalent elastic properties ?/µ and ?). Rocks with different ?/µ will be projected to the different angle and reflectivity. The equation which transforms ?/µ to reflection angle may be referred to as a Generalized Angle Transform Equation (GATE). Further details and advantages of various embodiments of the method are described in more herein.
