Mechanisms and control of water inflow to wells in gas reservoirs with bottom water drive
Water inflow may cease production of gas wells, leaving a significant amount of gas in the reservoir. Conventional technologies of gas well dewatering remove water from inside the wellbore without controlling water at its source. This study addresses mechanisms of water inflow to gas wells and a …

Automatic type curve matching for predicting gas wells production
The determination of gas wells production using type curve matching is one of the methods used in evaluating gas reservoirs. Matching curves manually is time consuming and exposed to human error. Aminian type curves unlike the other type curves accounts the pressure dependency of gas properties and …
