Modification of Pulse Decay Method for Determination of Permeability of Crystalline Rocks

An improvement of the pulse decay method rock permeability measurement is presented. The technique based on fitting experimental data to analytical and numerical solutions filtration equations derived with regard variation flowing gas properties temperature pressure. A special apparatus software for implementation this were developed. single experiment in which used as a medium enables determining both sample water Klinkenberg constant. measurements samples different types various reservoir carried out demonstrated satisfactory accuracy efficiency method. effective anisotropic proposed development technique.
