Abstract
There is provided system and methods for restimulating a hydrocarbon producing well using water and pressures below the closure pressure, which results in production rates approaching the initial production rate of the well. There is provided multiple restimulation techniques using water based fluids at or below the closure pressure of the well, which results in production rates approach that of the prior rate upon stimulation.
Claims3
A method of reducing the decline curve in production rate for an existing well in a formation, the method comprising:
- a. identifying a producing well that has a production rate, wherein the production rate is at least 20% below an initial production rate for the well;
- and wherein the well has a closure pressure;
- b. pumping a restimulation fluid into the well at a predetermined flow rate and predetermined pressure, wherein the closure pressure of the well is not exceeded;
- c. whereby, the production rate of the well is increased by not less than 50%.
