COURSE OVERVIEW:

Quantitative Interpretation (QI) using Seismic Data is an advanced discipline that integrates geophysics, rock physics, and petrophysics to predict reservoir properties from seismic amplitudes. Unlike traditional qualitative interpretation, which focuses on structural mapping, QI seeks to extract physical parameters such as lithology, porosity, and fluid type. This course explains the rigorous technical workflows required to transform seismic reflections into meaningful "elastic" volumes that can be used for field development and prospect de-risking.

The coverage includes the rock physics link between geological facies and seismic response, utilizing Amplitude Versus Offset (AVO) and seismic inversion techniques. Participants will learn how to condition seismic gathers and perform "well-to-seismic" ties to ensure that seismic wavelets are properly understood. The scope addresses the use of elastic attributes, such as Acoustic Impedance (AI) and $Vp/Vs$ ratios, to discriminate between brine-saturated sands, hydrocarbon-bearing reservoirs, and non-reservoir lithologies.

Furthermore, the course addresses the practical application of QI in different geological settings, from young clastic basins to complex carbonate plays and unconventional shales. Attendees will explore the use of Bayesian classification and multi-attribute analysis to create "Probability of Lithology/Fluid" maps. By the end of the course, participants will be able to design a QI project, select appropriate inversion algorithms, and utilize quantitative outputs to optimize well placement and volumetric assessments.

COURSE OBJECTIVES:

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

• Define the core components of a Quantitative Interpretation (QI) workflow.

• Perform seismic data conditioning for amplitude-preserved interpretation.
• Execute high-fidelity Seismic-Well Ties for wavelet estimation.
• Utilize AVO (Amplitude Versus Offset) for Direct Hydrocarbon Identification.
• Distinguish between AVO Classes I, II, III, and IV.
• Execute Post-stack and Pre-stack (Simultaneous) Seismic Inversion.
• Utilize $Vp/Vs$ and Poisson’s Ratio for lithology discrimination.
• Map Porosity and Net-to-Gross using inverted seismic volumes.
• Apply Gassmann’s Fluid Substitution for sensitivity analysis.
• Perform Bayesian Lithofacies Classification from seismic attributes.
• Identify and mitigate seismic "Tuning Effects" and resolution limits.

• Quantify the uncertainty in seismic-derived reservoir property maps.

TARGET AUDIENCE:

Geophysicists, Petrophysicists, and Reservoir Geologists who want to apply quantitative techniques to seismic interpretation and reservoir modeling.

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.
