Convolve the RC log with the Wavelet to generate a . Perform Time-to-Depth Conversion

Petrel is the industry-leading software designed to manage the entire E&P workflow, from seismic interpretation to simulation. Whether you are a petroleum geologist, geophysicist, or reservoir engineer, understanding the basic workflow is essential. Table of Contents Initial Project Setup & Data Import Seismic Interpretation Techniques Well Correlation and Log Data Structural Modeling (Faults & Horizons) Property Modeling and Upscaling Basic Reservoir Simulation Setup 1. Initial Project Setup & Data Import

This stage involves identifying geological features within the seismic data.

Use the tool to transfer the high-resolution geological cell values to the coarser simulation grid. petrel tutorial

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

Once logs are upscaled, distribute properties across the remaining undrilled cells using the and Petrophysical Modeling processes: Modeling Type Common Algorithms Used Facies Modeling Sequential Indicator Simulation (SIS), Object Modeling Populates discrete rock types (e.g., Sandstone vs. Shale). Petrophysical Modeling Sequential Gaussian Simulation (SGS), Kriging

: Import via Well Path/Deviation Format , specifying measured depth (MD), inclination, and azimuth. Ready to dive deeper

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

: Open a "3D Window" to visualize imported data and perform Quality Control (QC) to check for spatial inconsistencies. 3. Seismic Interpretation Workflow

: The step-by-step engine used to build the structural framework, populate properties, and initialize simulations. 2. Project Setup and Data Import

Best for distributing deterministic shapes like fluvial channels or sand lobes into a mud matrix. Initial Project Setup & Data Import This stage

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

Subdivide the primary geological zones into smaller horizontal increments. Select , Erosional , or Base-Conformable layering based on your depositional environment configuration. 5. Facies and Petrophysical Property Modeling

Good data management is the first practical step in any Petrel project. You will import various types of data, from well information to seismic horizons. The Input pane stores all raw data and is the source for all subsequent work.

: Calculate the Bulk Volume, Net-to-Gross, and Total Pore Volume of your 3D grid.
