Abstract
A method is for use with subterranean formations, such as oil and/or gas reservoirs. In some examples (e.g., production examples), the method improves the production from that formation. Some of the examples of the method describe selecting both an exertive force (e.g., a pressure) to apply at a wellbore, but together with a drawdown pressure at the wellbore to modify operations (e.g., improve production) at that subterranean formation. The selection of one or both of the exertive force and drawdown pressure may be based on the downhole environment at that wellbore, which can include the porosity and/or permeability of a near-wellbore formation radially surrounding a wellbore. The exertive force and drawdown pressure may be specifically selected to modify the porosity and/or permeability of the near-wellbore formation.
