Quick Look Prestimulation Well Test
Samei, E. and Hsieh, J.
A technique is presented that allows one to perform a short term well test. The short duration of the test results in reasonably good estimates of formation permeability, skin factor, and reservoir pressure. The technique is appropriately referred to as 'Quicklook.' The technique requires pressure measurement at the surface and also downhole. Subsequent to perforating, the formation is subjected to an instantaneous rate drawdown or injection for a couple of minutes. The instantaneous rate period is followed by a shut-in period of sufficient duration to achieve the desired radius of investigation. Three interpretation plots are made to perform the analysis: (A) a derivative type plot for flow regime identification and type curve analysis, (B) a specialized plot (Rate Convolved Horner analysis) for certain flow parameter calculations, and (C) a system verification plot.
