Reservoir Simulation & Modeling Consultants

Ridgeline Engineering is a reservoir simulation consultancy focused on building numerical reservoir models that simulate fluid flow in the subsurface. We develop dynamic simulation models that forecast primary, secondary, and tertiary production of hydrocarbons across conventional and unconventional plays. Our reservoir modeling consultants are also actively engaged in CCUS projects, modeling the injection of carbon dioxide in brine aquifers in support of Class VI permit applications.

Reservoir Simulation FAQ

What is reservoir simulation?

Reservoir simulation is the use of numerical models to predict fluid flow behavior in subsurface rock formations. Engineers build 3D computational models that represent the geology and fluid properties of a reservoir, then simulate production scenarios to forecast recovery, optimize well placement, and evaluate development strategies.

When should I hire a reservoir simulation consultant?

You should engage a reservoir simulation consultant when making capital-intensive decisions about field development, infill drilling, enhanced recovery, waterflood optimization, or carbon storage feasibility. Simulation provides quantitative forecasts that reduce risk and support investment decisions, regulatory applications, and reserves reporting.

What types of reservoir models does Ridgeline Engineering build?

Ridgeline builds full-field and sector simulation models for conventional reservoirs (waterfloods, gas injection, EOR), unconventional plays (integrated fracture and reservoir models), and CCUS projects (CO2 injection in brine aquifers). Our models are built on detailed geologic and geomodeling foundations and support history matching, production forecasting, completion optimization, and Class VI permit applications.
