Abstract
Methods and systems for detecting impact of induced micro-fractures in a subsurface formation are disclosed. The method includes determining an unloading effective stress (σ) in a formation sample taken from a wellbore drilled into the subsurface formation, determining a fracture closure stress (σ) of the formation sample, determining that the unloading effective stress (σ) is greater than or equal to the fracture closure stress (σ), and in response to determining that unloading effective stress (σ) is greater than or equal to the fracture closure stress (σ), operating the well system to inhibit impact of micro-fractures in the wellbore.
