The tutorial also includes a "Model Doctor's Diagnostic Checklist":
Use the Fault Modeling process to connect interpreted fault sticks into surfaces.
Populate porosity using , constrained by the facies model.
A structural grid is just an empty cage. Property modeling fills these empty 3D cells with geological and petrophysical data. Upscaling Well Logs petrel tutorial free
Identify discontinuities in the seismic reflections. Digitization of fault sticks on consecutive lines creates a 3D fault surface. Step 3.3: Structural Modeling (The Pillar Gridding)
Once the 3D framework is established, populate it with geological properties (Porosity, Permeability, Facies). 4.1 Facies Modeling Use well logs to define (e.g., Sandstone, Shale).
: Focusing on the Eclipse-to-Petrel workflow, PVT data, and fluid contacts [21]. Geological Modeling Guide The tutorial also includes a "Model Doctor's Diagnostic
Use to model permeability, using porosity as a secondary variable (if a relationship exists). Phase 5: Upscaling and Volume Calculation 5.1 Data Upscaling
Practice importing well heads, deviation surveys, well logs ( .LAS files), and 2D/3D seismic data ( .SEGY files). Phase 2: Seismic Interpretation Transform raw acoustic data into structural boundaries.
Use your density and sonic logs to generate a synthetic seismogram. Align this with your actual seismic data to confirm which seismic reflectors represent your geological horizons. Property modeling fills these empty 3D cells with
Static modeling is where the subsurface comes to life. Several free series, such as Petrel Tutorial 1: Simple Static Modeling , walk you through the structural workflow:
Once you have access to the software and a dataset (like Gullfaks), follow this standard industry workflow to build your first reservoir model. Step 3.1: Project Setup and Data Import
Go to File > Import File , select Well Files (LAS or ASCII), and ensure the well heads are correctly located. Seismic Data: Import SEG-Y files via File > Import File .
