Methods of estimating parameters fu00ecsicos, permeability, and the resistance of the surface of the fractured porous rocks of training subterru00e1nea containing a fluid reservoir compressu00ecvel, and.System for estimating parameters of a fu00ecsicos of porous rocks underground formation containing a fluid reservoir compressu00ecvel an analysis of loss of transient pressure before closing for a test injection of fracture / decline is used to mitigate the effects detriment Isa properties are dependent on the fluid pressure in the evaluation of physical parameters of reservoir.A test of injection of fracture / decline consists of an injection of liquid, gas, or a combination (foam, emulsion, etc.) containing the desired additives for compatibility with the formation to an injection pressure which exceeds the pressure of fracture formation, followed by a period. Of interruption.The decline of pressure during the period of interruption is measured and analyzed to determine the permeability and resistance from the face of the fracture, preparing a graph Cartesian specialized from the data of closure using pseudodados adjusted, such as data of pseudo pressu00e0o hel States and time as variables in a first method.And the data of pseudo pressure adjusted and pseudo time adjusted as variables in a second method. This analysis allows the data in the chart fall along a straight line, with the properties of fluid constant as dependent on pressure. The slope and intercept of the straight line are respectively indicative of the evaluations of permeability K and the resistance against F. Ratura 1%.
