Overview of SLB Flaresim 2025.3
SLB Flaresim (formerly Schlumberger Flaresim) is the industry-standard software for flare system design and simulation, primarily used in the oil and gas sector. Developed by professional engineers, it enables accurate modeling of thermal radiation, noise footprints, and dispersion effects from flare systems in offshore platforms, refineries, gas plants, and chemical facilities. The software predicts surface temperatures exposed to radiation, supports 3D flame-shape analysis with multi-stack flexibility, and evaluates scenarios under varying wind conditions. It also integrates with SLB’s Symmetry process simulation software for end-to-end process modeling.
Key applications include:
- Assessing health, safety, and environmental (HSE) risks related to flare emissions.
- Simulating combustible liquid dispersion during flame-out and flue gas dispersion.
- Generating comparative case studies within a single model for rapid design iterations.
Flaresim is a 64-bit Windows application, with a user-friendly interface for unit customization and detailed reporting.
