Özet

This paper summarizes the analysis of wireline formation tester (WFT) data collected in tight gas sands. An interpretation algorithm based on typo-curve matching is used in the analysis. The type curves are constructed using an analytical model. The model assumes hemispherical flow geometry and incorporates early time decompression period and flowline storage effect. The permeability values calculated using this algorithm agree reasonably well with the permeability values available from core measurements.
