1. A method of reducing the decline curve in production rate for an existing well in a formation, the method comprising:
a. pumping a restimulation fluid into the well at a predetermined flow rate and predetermined pressure, wherein a stasis is achieved that is at or below the closure pressure of the well;
b. wherein the restimulation fluid consists essentially of water;
c. wherein prior to step a) the well had a production rate, wherein the production rate was below an initial production rate for the well;
d. maintaining the stasis for about 15 minutes to about 3 hours;
e. whereby, the production rate of the well is increased.
