Open the CIPO recordAbstract From the Canadian patent
A novel method for characterizing multilayer subterranean reservoirs comprising forming a single layer reservoir model representative of the flow parameters of the multilayer reservoir and developing a set of predicted flow rates from a numerical reservoir simulator. The predicted flow rates are scaled to form a set of dimensionless flow rates. Differences between actual reservoir flow rates and predicted flow rates obtained from the dimensionless flow rates, are minimized automatically to obtain estimates of flow parameters for each layer of the multilayer reservoir. Additionally, for a given set of flow parameters, the optimum injection and production well patterns as well as injection …

Why it's free to use
- Filed December 12, 1991 and granted May 5, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 12, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 12, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
