Methods for initiating chemical reactions in a wellbore include delivering one or more reactive components via a carrier fluid to the wellbore. The one or more reactive components delivered to the wellbore are configured to enable one or more chemical reactions to occur. The one or more chemical reactions are carried out until a threshold volume of the one or more reactive components is delivered to the wellbore.

A system of producing subterranean fractures in geologic formations for the extraction of hydrocarbons includes flowing an air and fuel mixture into a well hole. The well hole may then be sealed with a packer plug creating a compression chamber with the air and fuel mixture. A liquid, such as water, may be pumped into the well hole to create pressure in the compression chamber. The build-up of pressure eventually causes auto-ignition of the air and fuel mixture which fractures the formation. The water may then rush into the compression chamber which thermally shocks the area causing additional fractures. The water may vaporize to steam and thoroughly disinfect the well hole eliminating the need for added biocides.

In downhole tools and methods related to stimulation of subterranean formations are provided. The tools and methods utilize electrically ignitable propellant to generate gas downhole that is used to generate or enhance fractures. The electrically ignitable propellant can be ignited applying electrical power to a pair of electrodes associated with the propellant. Subsequently, the ignition can be halted by ceasing to supply the electrical power. Thus, allowing for the control of the amount and location of generated gas.
