... Abstract Sometimes decline curves for tight gas wells indicate that linear flow may last for over 10 or 20 years. These decline curves may show outer boundary effects but no pseudo-radial flow. This paper presents decline curve analysis methods for such wells. Values for k xf and drainage area...

... references 5 to 7 may be consulted. These papers are concerned with vertical (linear flow) and horizontal (radial flow) fractures. A more realistic visualization of naturally fractured systems has been that of Barenblatt et al. 8 , further discussed by Warren and Root 9 , which represents the reservoir...

... ] which exhibits early time linear flow and intermediate time bilinear flow. Here we show for the first time that all these behaviors may be combined into a single, easily derived, exact solution in the Laplace domain. In the low conductivity limit, it is convenient to think of the dimensionless...
