Modeling and Simulation

Critical information for enhanced production

Sophisticated software is the basis for selecting the best recovery process and includes matching the right method to the unique properties of a specific heavy oil reservoir for optimum production.

Reservoir modeling

A reservoir model is a critical tool in optimizing recovery and financial performance providing state-of-the-art visualization, analysis of oil, gas, water, and solids behaviors, as well as uncertainty analysis and optimization, so that potential recovery and artificial lift methods can be evaluated.

Production planning

Pilot studies provide an insight into reservoir behavior enabling oil and gas companies to characterize a reservoir and manage it more effectively. Heavy oil reservoirs are often associated with soft, unconsolidated near-surface basins where wellbore stability can be an issue during drilling or production, and poorly-sorted heterogeneous sands can hinder steam chamber growth.

Simulation for producibility

Sand channels (or wormholes), the result of sand production in a geologic basin, mean that special reservoir simulation techniques must be incorporated to adequately model CHOPS and other production mechanisms. These must accurately describe the flow paths, pressure drawdowns, and stimulated productivity that occur because of those channels.

Economic modeling

Software enables economic modeling and evaluation of upstream heavy oil projects, providing the means to analyze risk, generate production forecasts, prepare customized reports, and perform sensitivity analysis including steam costs.
