The validity of the power law exponential decline in forecasting production in tight gas wells is tested using synthetic data. Introduction The production of tight gas is becoming commercially significant in North America...

... Abstract Decline analysis using Arp's equations is the primary empirical method used in the petroleum industry for estimating future reserve recovery and generating production forecasts. The development of tight gas and in particular shale gas reservoirs as important new sources of gas...

.... Such models are useful, when large number of sensitivity studies are necessary to evaluate the uncertainty in reservoir parameters and only limited specific properties of a hydrate reservoir are available. In this work, a tank-type material balance equation is considered. This is combined with the solution...

Therefore, this deficiency contradicts to the universality of these models. In this work by performing experimental activities on different crude oils...

... flow in SAGD is crucial to predict its effect on the process performance. One mechanism involved in the flow of gas is the viscous drag due to the falling liquids in the SAGD chamber. In this work, the production of gas in SAGD was studied by deriving flow equations that describe the viscous drag...
