COURSE OVERVIEW:

Geomodelling is the process of creating a digital, three-dimensional representation of the subsurface that honors all available geological, geophysical, and petrophysical data. This course focuses on the "rules" and best practices that ensure geomodels are not just mathematically sound but geologically realistic. Participants will learn how to synthesize diverse and often conflicting datasets into a coherent static model that serves as the foundation for reservoir simulation. The scope covers the entire workflow from structural framework construction to the stochastic population of facies and petrophysical properties.

The coverage of this course emphasizes the importance of a "concept-driven" approach to modeling. Attendees will learn how to define the appropriate cell size and grid orientation to capture critical reservoir heterogeneities without over-complicating the model. The curriculum details the rules for stratigraphic correlation, fault modeling, and the selection of appropriate algorithms for property distribution (e.g., Kriging versus Sequential Indicator Simulation). By following these rules, geoscientists can create models that provide a reliable estimate of volumes and a realistic framework for fluid flow prediction.

Furthermore, the course addresses the synthesis of subsurface data to manage uncertainty. Participants will explore how to build multiple scenarios that capture the range of possible geological interpretations. The course also discusses the importance of model "Quality Assurance" and "Quality Control," providing a checklist for validating the model against original data and geological expectations. By the end of the course, participants will be able to lead the construction of high-quality geomodels that bridge the gap between exploration and production, ensuring that the subsurface synthesis truly reflects the underlying geological reality.

COURSE OBJECTIVES:

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

• Define the fundamental rules for building realistic 3D geomodels.
• Synthesize geological, seismic, and well data into a unified model.
• Select appropriate grid scales and architectures for specific reservoirs.
• Construct geologically valid structural frameworks and fault models.
• Apply stratigraphic rules for horizon and layer definition.
• Utilize facies-controlled modeling to capture reservoir heterogeneity.
• Compare deterministic and stochastic property modeling algorithms.
• Implement data preparation and QC standards for geomodelling.
• Build multi-scenario models to quantify geological uncertainty.
• Perform volume calculations and sensitivity analysis on models.
• Validate the geomodel against well logs and production data.
• Ensure seamless integration between static and dynamic models.
• Communicate the limitations and confidence of the subsurface synthesis.
• Apply best practices for model documentation and version control.

TARGET AUDIENCE:

Geologists, Reservoir Engineers, and Geomodellers responsible for building and maintaining 3D reservoir models.

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.
