...Christine Ehlig-Economides; Michael J. Economides Prominent examples of linear flow behavior in the well test literature describe flow within or to a fracture penetrated by a producing well. The characteristic pressure transients generally are exhibited in the early portion of a well test...

...Robert D. Carter This paper presents gas-prpduction-rate results in type curve form for finite radial and linear flow systems produced at a constant terminal (bottomhole) pressure. These results can be used in the analysis of acfual gas and oil rate/time data to estimate reservoir size and to infer...

... into or out of the fracture by assuming elliptical flow and by using the pressures of the blocks surrounding those containing the fracture. The assumption that the flow into the fracture is everywhere perpendicular to the fracture plane (i.e., linear flow) and the effect of the skin factor are also...
