Petrel Tutorial [updated] 〈2K 2026〉

Petrel is a specialized software used primarily in the oil and gas industry for reservoir characterization and simulation. Since "prepare a text" is quite broad, I will interpret this as "Prepare a beginner's guide text explaining what Petrel is and how to start a typical workflow."

Data Organization: Use the Input Pane to manage your folders. Logical grouping of "Seismic," "Wells," and "Interpretations" is essential for complex projects. 2. Data Import and Management petrel tutorial

3.1 Fault Interpretation

Faults break the continuity of rock layers. Petrel is a specialized software used primarily in

1. Seismic Volume: Visualize seismic data in 2D and 3D.
2. Horizon Tracking: Pick and track horizons using automatic and manual methods.
3. Fault Interpretation: Interpret faults using various techniques, such as fault sticks and surfaces.

Finally, the model is ready for Volumetrics and Upscaling. Once the cells are populated, Petrel can instantly calculate the total volume of oil or gas in place by summing the values of the cells. This is often the primary deliverable for management and investment decisions. If the model is destined for reservoir simulation (dynamic modeling), it often must be "upscaled." A geological model might contain 50 million cells, which is too many for a fluid flow simulator to handle efficiently. Upscaling coarsens the model, reducing it to perhaps 100,000 cells while attempting to preserve the critical reservoir properties. Seismic Volume : Visualize seismic data in 2D and 3D

• Upscaling: Transfer 1D log data (like porosity and permeability) from wells into the 3D grid cells.
• Facies Modeling: Use algorithms (like Object modeling or Sequential Indicator Simulation) to distribute rock types (sand vs. shale) between the wells.
• Petrophysical Modeling: Populate the model with continuous properties like Porosity, Permeability, and Water Saturation, often constrained by the Facies model.

Property Modeling: Distribute petrophysical properties like porosity and permeability using algorithms such as Sequential Gaussian Simulation.

7. Quick QC checks

• Cross-plot well data vs. modeled grid values (Checks → Cross-plot).
• Inspect histogram and statistics of the modeled property (right-click property → Statistics).
• Visually check property continuity across faults and horizons.
