Abstract

Petroleum may be recovered from a sub-surface reservoir by reducing the break-down pressure of a geological formation from an original break-down pressure to a reduced break-down pressure by exothermically reacting one or more reaction components in a carrier fluid adjacent to or within the geological formation, and forming fractures in the geological formation by hydraulic fracturing the geological formation.
