The useful application of radial flow models is obviously dependent on making a reasonable estimate (assumption) of the extent of the region around a given well over the which the flow is radially symmetric.

Well tests conducted at a series of different flow rates for the purpose of determining well deliverability, typically in gas wells where non-Darcy flow near the well results in a rate-dependent skin effect. Multiple-rate tests are sometimes required by regulatory bodies.
Used to measure the flowing bottom-hole pressure of a reservoir to determine its productivity index, the flowing gradient of the well fluids, possible communication between zones, and to investigate the efficiency of the gas-lift valves. The pressure survey is carried… Read More ›
