Static 3D Modelling in Clastics Depositional Environment

The purpose of this 3D Modelling training is to acquaint petroleum geologists and engineers with techniques used to characterize hydrocarbon reservoirs, with specific focus on the construction of 3D static modeling especially in clastics deposition environment.

Participants will learn about the data required and the processes that should be followed when conducting a 3D static modelling especially in clastics depositional environment. Instructors will outline and describe the procedures for 3D static modeling and use case histories and exercises to illustrate the key points.

Day 1
Overview, Introduction for Geomodelling and Geostatistics:
  • Introduction to geomodeling (geological, geophysical, petrophysical and RE data integration)
  • Review on descriptive and inferential statistics, data analysis and data transformation.
  • Geostatistics, stationarity and concept of spatial heterogeneity; variogram calculation, setting and modeling; anisotropy, directional analysis and cross variogram.
  • Unsample locations and estimation methods (simple – ordinary – universal kriging, co-kriging, collocated co-Kriging) and simulation method (TGS, SIS, Object-based, SGS, etc.).
Overview of Structural Modelling and Geological Conceptual Model:
  • Fault network (complex structure, reverse fault, numerous fault; fault truncation, etc.).
  • Interpreted vs. calculated horizons; horizon modeling and data filtering.
  • Horizon truncation and onlapping.
  • Zonation and layering (isochore correction).
  • 3D grid concept (pillar, non pillar, zone, subgrid, staircase, etc.).
  • Review of carbonate conceptual geology, depositional environments and reservoir quality.
  • Facies interpretation (core interpretation, log – core calibration, facies interpretation in un-cored wells, etc.)
Day 2
Workshop: Structural Modeling, Data Loading, QC and Fault Modeling:
