COURSE OVERVIEW:

Seismic inversion is a sophisticated mathematical process used to convert seismic reflection data into quantitative rock and fluid properties. This course provides an advanced investigation into the various inversion algorithms, ranging from deterministic post-stack methods to complex stochastic pre-stack workflows. Participants will learn how to remove the "seismic wavelet" effect to reveal the underlying acoustic and elastic impedance of the subsurface.

The scope of this training focuses on the integration of seismic, well-log, and petrophysical data to create a high-resolution reservoir model. Attendees will examine the physical principles of AVO (Amplitude Versus Offset) and how simultaneous inversion allows for the decoupling of lithology and fluid effects. We will discuss the crucial role of the low-frequency model and how it constrains the inversion process to provide absolute property values.

Coverage includes the evaluation of inversion results through blind-well tests and statistical validation. By mastering these advanced inversion techniques, geoscientists can significantly improve the accuracy of porosity, lithology, and saturation predictions. This course is essential for technical professionals who require quantitative, high-fidelity subsurface descriptions for volumetric estimation and reservoir simulation.

COURSE OBJECTIVES:

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

• Explain the fundamental physical and mathematical concepts of seismic inversion.
• Differentiate between post-stack, pre-stack, and simultaneous inversion.
• Master the workflow for wavelet estimation and well-to-seismic calibration.
• Construct robust low-frequency models using well logs and seismic velocities.
• Utilize pre-stack simultaneous inversion to derive elastic parameters.
• Apply rock physics templates to interpret inversion results in terms of facies.
• Distinguish between deterministic and stochastic (geostatistical) inversion.
• Use inversion volumes to delineate reservoir "sweet spots" and fluid contacts.
• Perform quality control (QC) on inversion outputs using residual analysis.
• Integrate inversion results into the 3D static geological model.
• Quantify the uncertainty and resolution limits of seismic inversion.
• Leverage inversion for both exploration and field development objectives.
• Communicate inversion-derived property maps to reservoir engineers.

TARGET AUDIENCE:

Geophysicists, Petrophysicists, Reservoir Geologists, and Quantitative Interpreters specializing in reservoir characterization.

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.
