Select the tool from the seismic interpretation toolbar.

Once the empty 3D grid cells are built, they must be populated with geological properties using geostatistical algorithms. Scale-Up Well Logs (Upscaling)

Insert your seismic surfaces and well tops into the 3D grid framework to define the main structural boundaries.

Run the simulation to obtain Gross Rock Volume (GRV), Net Rock Volume (NRV), Pore Volume (PV), and total Stock Tank Oil Initially In Place (STOIIP). Data Exportation petrel tutorial

Use the Check Data and Volume Calculation tools to estimate Original Oil in Place (OOIP) or Gas in Place (GIP).

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

Located at the bottom left, this lists workflow steps in chronological order, from data import to simulation. Select the tool from the seismic interpretation toolbar

The first step in any Petrel workflow is setting up the project environment correctly to ensure all spatial data aligns. Create a New Project : Navigate to the menu and select New Project Define the Coordinate Reference System (CRS) : This is critical for locating your data on the map. Go to Project Setup Project Settings Coordinates and Units to select the appropriate CRS for your field location. Set Unit Systems

Subdivide zones into thin vertical cell layers (e.g., 1-meter layers). This vertical resolution is crucial for capturing fluid flow behaviors during simulation. 5. Property Modeling

thickness each) using , Fractional , or Follow Top/Base settings. This ensures the cells capture vertical reservoir heterogeneity. 6. Petrophysical and Facies Property Modeling Run the simulation to obtain Gross Rock Volume

Generate a to tie your well logs (depth domain) to your seismic data (time domain) using a checkshot survey. Select the Horizon Interpretation tool.

Go to the or Corner Point Simulation toolsets and select Volume Calculation .

Right-click the interpreted horizon and select to convert the sparse points into a continuous structural surface using convergent interpolation algorithms. 3. Well Correlation and Stratigraphy
