Seismic interpretation maps the structural framework of the subsurface by picking major faults and key geological horizons. Fault Interpretation

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

Watch this short video to learn how to create a new project and define the Coordinate Reference System (CRS) in Petrel:

The first step in any Petrel project is defining the framework to ensure data from different sources (seismic, wells, maps) aligns correctly. Coordinate Reference System (CRS): Found under File > Project Setup > Project Settings > Coordinates . You must define the projection and datum. Units System: Select between

Use the Template Folder to define log types (Gamma Ray, Resistivity, Porosity). petrel tutorial

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

Once properties are populated, the model becomes quantitative. Using the Volume Calculation tool, users compute:

Convolve the wavelet with the reflection coefficients to generate a synthetic trace.

Define by specifying where the production casing is perforated within your 3D grid layers. Seismic interpretation maps the structural framework of the

The first step is establishing a workspace with the correct spatial parameters. : Go to File > New Project .

Insert your seismic-interpreted surfaces into the 3D grid to define the vertical layers. 6. Property Modeling

cells) for engineering simulators to process efficiently. Upscaling condenses grid layouts into larger, coarser cells while retaining regional flow dynamics. Create a coarser grid via the process. Well Correlation and Stratigraphy Watch this short video

After modeling properties, calculating the Original Hydrocarbons in Place (OIIP/GIIP) is vital.

With the fault framework locked in, you can transform 2D horizons and sparse well data into precise, sealed 3D structural surfaces.

Petrel will generate vertical, inclined, or curved pillars along your fault planes to align the grid cells with your structural trends. Horizon Making and Layering

A robust subsurface model relies on four primary data types: well headers, well tops (markers), well logs, and seismic data. Well Headers
