Gas diverter for well and reservoir stimulation

Abstract

The fracturing methods described in the present disclosure provide advantage over the current fracturing methods. The disclosed fracturing methods can change the fracture gradient of the downhole subterranean formation. For example, one or more of the fracture gradients of the low and high stress zones of the downhole subterranean formation can be changed. Furthermore, the methods of present disclosure, in relation to current practices, can decrease the extent and / or degree of fracturing within low stress downhole formations and increase the degree of fracturing within high stress formations.

AI Technical Summary

Benefits of technology

The present patent describes a process for changing the fracture gradient of a downhole formation in a wellbore. The process can decrease the extent and degree of fracturing in low stress formations and increase it in high stress formations. The process can be conducted without solid particles and can be used in any well bore orientation. The process can also involve introducing a foam mixture into the subterranean formation to increase the pore pressures and change the fracture gradients. The process can protect a target well from being fractured and can shield and protect the target formation from being fractured by adjacent interfering wellbores.

Problems solved by technology

More particularly, the process of the present disclosure in relation to current practices can decrease the extent and / or degree of fracturing within the low stress downhole formations and increase the degree of fracturing within the high stress formations.

It can be appreciated that solid particles can be detrimental to well health and productivity.
