Method for determining fracture closure pressure and fracture volume of a subsurface formation

Patent ·
OSTI ID:5797260
;
This patent describes a method of determining characteristics of a fracture subterranean formation. It comprises injecting fluid into a wellbore penetrating the subterranean formation to generate a fracture in the formation; measuring pressure of the fluid over time after injection of the fluid has ceased; and determining fracture closure pressure at onset of constant volume behavior of the pressure and time measurements, wherein the constant volume behavior is determined by the pressure and time measurements.
