Abstract
Among other things, methods and systems are described for calculating formation breakdown pressures. A method involves determining, during hydraulic fracturing operations, a pore pressure for a wellbore; determining a poroelastic stress for the wellbore using a poroelastic stress equation and based on the pore pressure; determining, during the hydraulic fracturing operations, a breakdown pressure upper bound for the wellbore; applying, during the hydraulic fracturing operations, a stress correction on the breakdown pressure upper bound based on whether the wellbore is an open hole wellbore or a cemented liner wellbore; and determining, during the hydraulic fracturing operations, a breakdown pressure for the wellbore based on the stress-corrected upper bound breakdown pressure for the wellbore.
