A variable predictor for predicting fluid flow rates from a reservoir to a wellbore.

摘要

A well control method comprising the steps of drilling a first wellbore and predicting a change in flow between a second wellbore and a reservoir prior to the change occurring. At least a first and second drilling operation variable is sensed while drilling the first wellbore and a predictive device is trained to predict at least one of the variables at a future time in a second wellbore, said predicted variable being a change in flow rate between a reservoir and the second wellbore. The future time may be when only one of the sensed variables is available. The at least one sensed variable may be a rate of fluid flow, pressure, pressure differential, surface temperature, down hole temperature, multiphase fluid flow rate and single phase flow rate. The predictive device may be a neural network, an artificial intelligence device (AI device), a genetic algorithm, a regression analysis, utilizing granular computing or an adaptive model.
