Abstract
A bio-composite solution that includes crushed coffee waste, colloidal nanosilica, and an activator is injected into a fracture zone of a subterranean formation. The bio-composite solution is cured at a downhole temperature in the fracture space to form a rigid solid gel. The rigid solid gel is strengthened due to the presence of coffee waste in its matrix and can block water flow from an overlying aquifer zone through the fracture into a production well.
