Petrel Tutorial Access

: Use the Cache to Disk option on massive seismic volumes to free up active system RAM.

Fault modeling is a crucial phase. It defines the tectonic skeleton of your reservoir and establishes how fluid paths are segmented.

Right-click the Wells folder in the Input Pane, select Import Selection , and choose Well heads ( . ) . Map your columns to Well Name, X Coordinate, Y Coordinate, and Surface Elevation (KB) .

This comprehensive tutorial provides a step-by-step roadmap to mastering the core workflows of Petrel. It covers everything from project initialization to reservoir risk analysis. 1. Project Initialization and Coordinate Systems

as a guide for loading well headers first, followed by deviations and finally well logs (typically LAS files). petrel tutorial

: Frequently check cross-sections using a Intersection Window to verify that property models match up accurately with real well markers.

Use Sequential Gaussian Simulation (SGS) to populate continuous properties like porosity and permeability. Ensure you constrain the petrophysical properties to your facies model (e.g., populate porosity only within the sandstone facies). 6. Volumetric Calculations

Select a predefined geographic or projected coordinate system (e.g., WGS84 UTM Zone 31N).

Once properties are populated, the model becomes quantitative. Using the Volume Calculation tool, users compute: : Use the Cache to Disk option on

Distribute porosity and permeability within facies using Sequential Gaussian Simulation (SGS) .

Create a 3D or Interpretation Window . Horizon Interpretation: Activate the Interpretation tab.

Define the Net-to-Gross (NTG) cutoff values to filter out non-reservoir rocks.

: Prepare the model for dynamic simulation by defining fluid properties and initial conditions. Right-click the Wells folder in the Input Pane,

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

Pillar gridding is the process of building the skeleton of your reservoir model. It transforms your interpreted surfaces and faults into a cellular 3D framework. Fault Modeling Define how your interpreted fault pieces interact.

Create fault surfaces and define connections, creating a Fault Framework . Pillar Gridding: Define grid pillars based on faults.

Generate the horizontal bounding skeleton of your model. Define your cell sizes (typically ) based on computing limitations and structural complexity. 3. Make Horizons
