    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
    Day 1
    • Introduction to subsurface modeling
    • Structural Framework and the concept of Volume-Based Modeling (VBM).
    • Fault modeling.
    Day 2
    • Boundary definition and model construction
    • Enhanced quality checks and modeling
    • Model refinement and depospace calculation
    Day 3
    • Structural gridding for stair-stepped grids
    • Structural gridding for depogrids

    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

    General knowledge of petroleum geology, structural geology and geophysics. Getting started with Petrel eLearning or equivalent Petrel experience is necessary.
