Fetkovich aquifer

WebJun 22, 2012 · Fetkovich’s Method • Fetkovich (1971) developed a method of describing the approximate water influx behaviour of a finite aquifer for radial and linear geometries. In many cases, the results of this model closely match those determined using the Van Everdingen-Hurst approach. WebJul 30, 2011 · The fact that the reservoir-aquifer boundary pressure is not constant with time gives rise to computational challenges. Most authors seek to eliminate this disadvantage …

WebOct 18, 2024 · The reason for E100's behavior is that NANAQU on the AQUDIMS keyword is for the maximum number of analytic aquifers, which includes both Carter-Tracy and Fetkovich aquifers (as well as others). So one can envisage the scenario that the engineers might use both types of aquifers and hence the "flexibility" of the AQUFETP … WebJan 28, 2024 · This is the simplest aquifer model and assumes that the rate of water influx is proportional to pressure drawdown. In this model, it is assumed that the aquifer volume is much larger than the gas reservoir and remains at the initial pressure. Using this model, the only parameter to solve for is the transfer coefficient (J). Fetkovich buoni postali a2 https://epsghomeoffers.com

WebThe aquifer flow model is radial and limited. The models discussed -- van Everdingen & Hurst, Fetkovich, Carter & Tracy, and Leung -- are all applicable to radial and limited aquifers. Some inaccuracy is observed when they are applied to extensive aquifers, and to a brief reservoir production time. WebFetkovich originally developed his type curves for gas and oil wells that are producing at constant pressures. Carter (1985) presented a new set of type curves developed … WebRaquifer. Raquifer estimates the cumulative water influx into hydrocarbon reservoirs using un-steady and pseudo-steady state modeling approaches. It generates a data frame of cumulative water influx over time for edge-drive and bottom-drive aquifers.

This paper demonstrates that decline curve analysis not only has a solid fundamental base but also provides a tool with more diagnostic power than has been suspected previously. The type curve approach provides unique solutions on which engineers can agree or shows when a unique solution is not possible with a type curve only. WebAug 4, 2024 · The Fetkovich analytic aquifer model is based on the principle of material balance; that is, the volume of water at the initial time under the current pressure should be equal to the sum of the pore volume under the current pressure and the volume of water invading the adjacent reservoir ( Fetkovich, 1971 ).
