Once the wells are established, the next phase is . This involves creating the skeleton of the reservoir. In a traditional workflow, the user interprets seismic data to generate horizons (surfaces representing the top and base of the reservoir) and faults. The user then constructs a "pillar grid," a 3D lattice that defines the geometry of the reservoir. Imagine constructing a building: the horizons and faults are the floors and walls, and the pillar grid is the steel framework that holds everything together. This step is crucial because it respects the structural complexity of the field; if a fault is modeled incorrectly, the fluid flow simulation later on will be inaccurate.
. It bridges the gap between seismic data and reservoir simulation, allowing geoscientists to build comprehensive "Seismic-to-Simulation" workflows. petrel tutorial
Horizons follow seismic reflectors.
This stage involves identifying geological features within the seismic data. Once the wells are established, the next phase is
Seismic interpretation is a critical component of Petrel. The software provides various tools for seismic data analysis, including: The user then constructs a "pillar grid," a
