HR-250 Pro4D (Time-Lapse Seismic Analysis) Workshop

Audience

Geophysicists, geologists, engineers and technical staff who want to understand the theoryand learn how to apply these increasingly critical techniques.

Content

This course covers the theory and practical use of Pro4D, an interactive program that is fullylinked within HampsonRussell software and performs time-lapse, or 4D, modeling and analysis.Topics include:

Time-Lapse Modeling: Log editing and synthetics, Biot-Gassmann fluid replacement modeling, Zoeppritz and elastic techniques, systematic methods and the wedge model Seismic Comparison, Calibration and Interpretation: Survey regridding, volume comparison using correlation, difference and cross-plotting, seismic calibration with time and phase shift, application of gain, shaping filters and simultaneous phase and time matching, crossnormalization, volumetrics and interpretation

Learning Objectives

This course covers the theory behind 4D analysis: modeling reservoir changes and comparing seismic volumes
Rock and fluid properties are discussed in detail. Practical application to modeling log data for a range of time-lapse scenarios, such as saturation or pressure changes
Volumetric analysis and matching mapped 4D response with known production information
50% of the course comprises practical exercises using the PRO4D software
