B-8 OPTIMIZING PETROPHYSICAL MODELING AND SEISMIC AMPLITUDE ANALYSIS USING A CONSISTENT HIGHLY INTEGRATED WORKFLOW PROCESS BRIAN O’NEILL and ALAN FUQUA Texaco Upstream Technology 4800 Fournace Place Bellaire TX 77401 USA Abstract 1 Specialists involved in seismic amplitude analysis are confronted with a wide array of data types petrophysicalmodeling methods and display capabilities. A high degree of interdisciplinary integration and organization are required to fully exploit this technical diversity. Proper modeling of ultrasonic shear-wave and compressional velocities is required to understand the interrelationship of rock mineralogy lithology porosity pore-fluid properties & distribution and how these properties vary with temperature and pressure.
