US12449245 - Power charge ignition

A method and apparatus for igniting a power charge in downhole wellbore using an ignition propellant mixed with a main propellant, the ignition propellant may be concentrated at the first end of a housing where it is the majority propellant and then gradually mix with the main propellant, transitioning to a majority of the main propellant.

The patent describes a setting tool designed for downhole wellbore applications that utilizes a dual-propellant system, where an ignition propellant is concentrated at one end and gradually mixes with a main propellant. Upon ignition, the resulting pressure drives a piston, facilitating the tool’s operation.

Claim 1

A setting tool comprising: an igniter; a power charge having a first end, a second end, a mid-section, a main propellant within the housing proximate the mid-section comprising a main propellant, and a first ignition portion within the housing proximate the first end comprising a first mixture of the main propellant and an ignition propellant; and a piston; wherein the igniter ignites the first ignition portion which produces pressure that drives the piston. an igniter; a power charge having a first end, a second end, a mid-section, a main propellant within the housing proximate the mid-section comprising a main propellant, and a first ignition portion within the housing proximate the first end comprising a first mixture of the main propellant and an ignition propellant; and a piston; wherein the igniter ignites the first ignition portion which produces pressure that drives the piston.
