COURSE OVERVIEW:

3D Geological Modeling Fundamentals provides a comprehensive introduction to the essential concepts and workflows used to create digital representations of the subsurface. This course focuses on the structural and petrophysical building blocks necessary to construct a robust 3D model that honors all available geological, geophysical, and petrophysical data. Participants will learn how to transform 1D well data and 2D/3D seismic interpretations into a consistent three-dimensional grid.

The scope of this training covers the entire modeling chain, from initial data quality control and structural framework construction to facies and property modeling. We explore the importance of stratigraphic correlation and fault network modeling in defining the internal architecture of the reservoir. Attendees will be introduced to the statistical and geostatistical methods used to populate 3D grids with properties such as porosity, permeability, and water saturation while maintaining geological realism.

Coverage includes the evaluation of model uncertainty and the validation techniques used to ensure that the final 3D geomodel is fit for purpose, whether for volumetric calculation or as an input for reservoir simulation. By the end of the course, participants will understand how a well-constructed 3D model serves as the central integration point for multidisciplinary subsurface teams. This course is a vital foundation for any geoscientist involved in modern exploration and production.

COURSE OBJECTIVES:

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

• Define the core components and purposes of a 3D geological model.
• Perform comprehensive data QC on wells, seismic, and core data for modeling.
• Build a robust 3D structural framework including faults and horizons.
• Define and implement stratigraphic sequences within a 3D grid.
• Create and manipulate 3D pillar grids and corner-point grids.
• Upscale well log data into 3D grid cells using appropriate statistical methods.
• Apply basic geostatistical techniques like Kriging and Stochastic simulation.
• Perform facies modeling using object-based and pixel-based methods.
• Populate models with petrophysical properties (porosity and permeability).
• Integrate seismic attributes as trends to guide property distribution.
• Calculate hydrocarbons in place (STOIIP/GIIP) directly from the 3D model.
• Assess and communicate the sources of uncertainty in a geological model.
• Validate the model through cross-sections and statistical comparisons.

TARGET AUDIENCE:

Geologists, Geophysicists, Reservoir Engineers, and Junior Modelers who need to understand the fundamental principles of 3D subsurface construction.

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.
