Petrel Structural Modeling: Structural Framework Workflows

This course presents the Petrel* software workflows used to build structural frameworks and geocellular grids integrated with domain knowledge. It aims to improve your reservoir modeling skills and help you achieve a better understanding of the overall reservoir structure.

The training includes:

  • An introduction to subsurface modeling
  • An overview of the structural framework modeling workflow
  • Discussion about the different types of fault complexities you are likely to see in a hydrocarbon reservoir and how you can model them with fault framework modeling
  • The construction of the reservoir horizons at both the unrefined and refined stages, with the creation of the zone model
  • How to detect common input data issues, as well as different techniques and tools of quality control to avoid inconsistencies at different stages during the modeling cycle
  • The 2D reconstruction workflow
  • The computation of a depositional space as well as its differences with the 2D reconstruction workflow
  • Structured stair-stepped grids and unstructured depogrids, and advantages and disadvantages for each of the two

Learning activity mix

Development and exploration geologists, geophysicists, petroleum engineers, managers, reservoir engineers and technical personnel with prior experience in Petrel.

  • Create structural models in Petrel using the Volume-based modeling algorithm
  • Create the fault framework based on provided input data
  • Assess the fault framework and edit the result
  • Run the Model construction process
  • Create and use the Horizon filtering attribute in the Model construction workflow
  • Use important structural operation tools to quality check your model
  • Incorporate the 2D reconstruction tool with horizon modeling in the structural framework
  • Use advanced options of the Volume-based modeling algorithm for horizon modeling
  • Refine and construct zones for the structural framework model
  • Build a depositional space to create an unfolded and unfaulted representation of the structural framework model
  • Construct a stair-stepped corner point grid from a structural framework
  • Generate the stair-stepped grid using the Depospace transform
  • Use a stair-stepped grid in a dual-scale reservoir model (coarse-fine-coarse) workflow
  • Build a depogrid from a structural framework model
  • Create segmentations of your stair-stepped grids and depogrids
