... Abstract The paper demonstrates that the transient flow regime in multi-fractured horizontal wells, often interpreted as linear flow, is more likely elliptical flow. Elliptical flow often cannot be distinguished from linear flow at earliest times, but the apparent transition between transient...

... Abstract This paper explores the application of two techniques to rate and pressure transient analysis of fractured wells in tight reservoirs. The first one is the Linear Flow Volume ( LFV ), defined as a region with size determined by a characteristic distance proportional to but smaller than...

And with known permeability, the ( x f √k ) coupled parameter can be resolved yielding effective fracture half length as well as the fracture...

Unfortunately, the inversion of the general Laplace solution was shown to be too complex. Therefore, the pressure and pressure derivative type...
