15/1/2018, · Mechanism. Hydraulic ,fracturing, is the process of pumping ,fluid, into a wellbore at an injection rate too high for the formation to accept without breaking. During injection, the formation’s resistance to flow increases, and the pressure in the wellbore increases to a value called the break-down pressure, which is the sum of the in-situ compressive stress and the strength of the formation.
