Identify discontinuities in the seismic reflections. Digitization of fault sticks on consecutive lines creates a 3D fault surface. Step 3.3: Structural Modeling (The Pillar Gridding)
However, official training from Schlumberger costs thousands of dollars. This is precisely why the demand for a search query has skyrocketed.
This is the most overlooked resource. If you are affiliated with a university that has a university software grant, or if your company has a maintenance contract, you have access to within the Schlumberger (now SLB) support center.
A complete Petrel 2020 project with pre-loaded data from Svalbard, used in the University Centre in Svalbard's AGx51 course:
Instead of just listing tools, provide a structured mini-project that takes a user from raw data to a basic 3D reservoir model.
Several seismic interpretation tutorials use public-domain data specifically released for educational purposes, allowing students to practice seismic interpretation methods without licensing restrictions.
Fault modeling, pillar gridding, and horizon modeling. Property Modeling: Facies and petrophysical modeling. Free Petrel Tutorial: Step-by-Step Workflow
While you can learn 70% of Petrel for free, you will hit a wall:
: A practical guide focusing on data entry, wellhead file input, and the initial steps of building a 3D model.
For learners who prefer reading to watching videos, several PDF resources are available for free download:
This series of covers seismic interpretation, modeling, and well design. It starts from the very basics and includes supporting data for practice. Each lesson is detailed and high-quality, designed so you can follow along step by step. The content builds from initial data import through advanced geological modeling modules.
Focuses heavily on subsurface workflows, structural geology in Petrel, and well correlation.
Direct interpretation of 2D/3D seismic data.
Track continuous seismic reflectors across your 3D volume. Use the "Auto-tracking" tool for clear, strong reflectors, and manually pick horizons where faults disrupt the signal.
