Petrel Tutorial [new] Access

Use the process to compute Pore Volume, STOIIP (Stock Tank Oil Initially In Place), and GIIP (Gas Initially In Place) based on the modeled porosity and saturation. Key Tips for Successful Petrel Workflows

With your data QC'ed and loaded, the next step is to extract geological information from it.

Execute the process to output the or Gas Initially In Place (GIIP) statistics directly into your Results window. 7. Model Upscaling for Dynamic Simulation Geological static models are frequently too dense ( 10710 to the seventh power 10810 to the eighth power

You cannot learn Petrel by reading only. You must click.

Use alignment markers to stretch or squeeze the synthetic trace to match the real seismic data. petrel tutorial

Divide zones into vertical micro-layers (e.g., proportional, parallel to top, or parallel to base) to match the vertical resolution of your reservoir well logs. 6. Property Modeling (Facies and Petrophysics)

The trick here is understanding Petrel’s Input pane —a tree structure that organizes everything you’ll build upon.

With your data safely loaded, the next phase is defining the structural framework by interpreting faults and horizons. Seismic-Well Tie Calibration

Now we bring well logs into the 3D grid. Use the process to compute Pore Volume, STOIIP

This is the construction of the 3D "cage" that defines the volume and shape of your reservoir.

Faults act as structural traps or fluid barriers. Mapping them is the first step in structural modeling. Go to the process tab. Select the Fault Interpretation tool.

This stage involves identifying geological features within the seismic data.

Set the desired I-and-J direction cell dimensions (e.g., cell size of 50m x 50m) based on computation limits and data resolution. Making Horizons, Layering, and Zones Use alignment markers to stretch or squeeze the

Use interpreted seismic horizons to guide surface generation, using algorithms like Convergent Modeling to ensure proper layer thickness.

Set the vertical and horizontal units (meters or feet) to ensure consistent depth parsing. Step 2: Importing Subsurface Assets

direction) of the model. Choose between proportional slicing, follow-top, or follow-base options. Set layer thicknesses (e.g., 1 meter layers) appropriate for captures of sand-shale variations. 6. Property Modeling (Facies and Petrophysics)
