COURSE OVERVIEW:

Seismic Petrophysics is the fundamental discipline that integrates high-resolution borehole measurements with regional seismic data to characterize reservoir properties. This course explores the complex relationships between rock mineralogy, pore architecture, fluid content, and the resulting elastic properties measured by seismic waves. Participants will investigate the theoretical and empirical models required to bridge the gap between the "log scale" and the "seismic scale," ensuring that subsurface models are physically consistent across all domains.

The scope of this training encompasses the advanced application of rock physics templates (RPT) to interpret seismic inversion volumes and AVO signatures. Attendees will learn to perform rigorous fluid substitution using Gassmann’s equations and analyze the impact of clay content, porosity types, and pressure on seismic velocities. We will specifically focus on the "well-to-seismic" calibration process, identifying why discrepancies often exist between core-derived data and geophysical observations and how to reconcile them through advanced upscaling techniques.

Coverage includes the evaluation of unconventional reservoirs, where geomechanical properties and anisotropy play a crucial role in seismic response. By mastering the workflows of seismic petrophysics, geoscientists can more accurately predict reservoir "sweet spots" and quantify the probability of hydrocarbon success. This course provides the quantitative framework necessary for modern reservoir characterization and risk assessment in both clastic and carbonate environments.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the physical links between petrophysical properties and seismic elastic constants.
• Execute advanced fluid substitution workflows using Gassmann’s theory and its limits.
• Construct and utilize Rock Physics Templates (RPT) for lithology and fluid prediction.
• Analyze the impact of pore geometry and aspect ratios on seismic velocities.
• Apply various upscaling methods to bridge well log data to seismic frequencies.
• Evaluate the effect of clay mineralogy and distribution on rock stiffness and Vp/Vs.
• Integrate core laboratory measurements (ultrasonic) with log and seismic data.
• Perform multilinear regression and neural network analysis for shear wave prediction.
• Assess the impact of effective stress and temperature on seismic rock properties.
• Quantify seismic anisotropy and its petrophysical drivers in shales and fractured rocks.
• Utilize seismic petrophysics to calibrate AVO attributes and inversion results.
• Identify Direct Hydrocarbon Indicators (DHIs) based on rock physics principles.
• Communicate petrophysical uncertainties to the geophysical and engineering teams.

TARGET AUDIENCE:

Petrophysicists, Geophysicists, Reservoir Geologists, and Quantitative Interpreters who specialize in integrating borehole and seismic data.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
