Discover proven strategies for safeguarding critical assets. Read the blog to learn how OLI’s tools improve reliability in Oil & Gas operations.
Protect assets. Predict risk. Optimize performance.
Oil & Gas Chemistry. Engineered.
OLI applies electrolyte thermodynamics to model corrosion, scaling, phase equilibria, and contaminant chemistry across oil and gas assets. From high-pressure wells to refinery overhead systems, our simulations reflect real process conditions and provide the foundation for operational and design decisions.
Thermodynamic Modeling in Oil and Gas
Scale, corrosion, gas sweetening and produced water treatment are expressions of fluid chemistry. Many operational risks and performance limitations originate in how chemistry evolves across wells, topside facilities, produced water treatment facilities and refineries. OLI translates complex chemistry and multiphase behaviour into first-principles modeling frameworks that predicts chemical speciation and phase interactions, enabling operators to design and operate grounded in thermodynamics.
Relied upon for Critical Chemistry Decisions
Used by operators and engineering teams to evaluate corrosion mechanisms, assess scaling potential, and support compliance planning using rigorous, first-principles chemistry modeling.
Electrolyte Thermodynamics Across the Asset Lifecycle
From reservoir to refinery, predictive electrolyte modeling clarifies chemistry risk and supports design decisions while strengthening reliability across oil and gas assets.
Upstream
Evaluate scaling and corrosion risk, completion fluid chemistry, produced fluid changes and gas/oil/water treatment processes using thermodynamic electrolyte models that reflect reservoir and surface conditions.
Midstream
Model gas sweetening, MEG and methanol treatments, contaminant behavior, and fluid property changes as pressure, temperature, and composition evolve during transport and processing.
Downstream
Evaluate refinery chemistry and corrosion risk from tank farm through desalting, distillation, conversion units using electrolyte models. Predict contaminants fate, fouling, scaling, corrosion, and support materials selection and IoW definition.
