Abstract
A downhole sealing apparatus comprises a propellant section and a sealing element section adjacent the propellant section. The propellant section comprises an outer housing, at least one propellant structure within the outer housing, and at least one initiator device adjacent the at least one propellant structure. The sealing element section is configured to isolate a region of a borehole in a subterranean formation responsive to pressure of gases produced through combustion of at least one propellant of the at least one propellant structure of the propellant section. A downhole assembly and a method of isolating portions of a borehole in a subterranean formation are also disclosed.
