Imported via LAS or ASCII files. These provide the "truth" at specific points in the ground.
A model is only as good as the data you feed it. Most tutorials focus on these three core imports:
Select wells and open a new Well Correlation Window . petrel tutorial
This step, known as a , creates a synthetic seismic trace from well log data (sonic and density). By matching this synthetic trace to the real seismic data at the well location, you establish a crucial link between the depth domain of your wells and the time domain of your seismic data. This process is a well tie and often involves loading checkshot data and extracting a wavelet.
If your Pillar Gridding fails or shows execution errors, look for intersecting fault sticks or self-crossing interpretations. Clean up the source interpretation line-by-line in a 3D window. Imported via LAS or ASCII files
Use the function to view the structural geometry of the basin relative to a specific depositional timeline. 5. 3D Structural Modeling (Corner-Point Gridding)
Before running a dynamic fluid simulation, calculate the original hydrocarbons in place and optimize the grid size to save computing time. Volumetric Calculations Most tutorials focus on these three core imports:
This blog post draft provides an introductory guide to , the industry-standard software for subsurface interpretation and modeling. It is designed for students or geoscientists new to the platform. Master the Subsurface: A Beginner’s Guide to Petrel
provides an integrated workspace from seismic interpretation to simulation, enabling geoscientists and engineers to build accurate, static, and dynamic subsurface models. This step-by-step tutorial covers the entire workflow required to build a robust, 3D structural and petrophysical reservoir model. 1. Project Setup and Data Import
Seismic interpretation maps the structural framework of the subsurface by picking major faults and key geological horizons. Fault Interpretation
