Effect of Effective Pressure on the Permeability of Rocks Based on Well Testing Results

During the development of oil and gas fields, permeability reservoirs decreases due to a decrease in reservoir pressure an increase effective pressure, as result which significant reserves remain reservoir. To predict rate production rates during field respond quickly, it is necessary know law with pressure. Existing methods for describing change rocks were analyzed paper. Numerical analysis results core studies from previously published papers well testing on examples north Perm region fields showed that both cases, regardless type rock reservoir, can be described by same equations (exponential power-law). Obtained used changes terrigenous fields. At time, according testing, intensive observed Analysis nature using Two-Part Hooke’s Model irreversible deformations are currently taking place formations under consideration. Predicting allow optimize deposits.
