Productivity of wells at oil and gas field while reducing the bottomhole and formation pressure

Authors: D.A. Martyushev, V.A. Mordvinov (Perm National Research Polytechnic University, RF, Perm)

Key words: productivity factor, seam pressure, formation pressure, deformations, gas content.

The article regards the features of the wells productivity coefficient changing with a decrease in formation and downhole pressures by the example of Magovskoye deposit (to T-fm). The authors made the calculations and created maps of changes of natural fractures openness in the reservoir areas drained by individual wells.
