The patent describes a propellant container for a perforating gun that features a lower cap housing multiple pieces of propellant, which are secured by an upper cap. The design allows for controlled combustion rates and surface area changes during ignition, enhancing the performance of the propellant.

Claim 1

1 . A propellant container for a perforating gun, comprising: a lower cap having an open end; two or more pieces of propellant housed within the lower cap; and an upper cap matable with the lower cap at the open end via an interference fit, an adhesive, a wax, a threaded interface, or a combination thereof, wherein mating the lower cap and the upper cap secures the two or more pieces of propellant within the propellant container for use within the perforating gun, wherein a rate of combustion of at least one of the two or more pieces of propellant increases at a greater than linear rate and a surface area of the at least one of the two or more pieces of propellant increases during combustion until consumed by the combustion, and wherein at least one of the two or more pieces of propellant does not combust at an increasing rate after being ignited. a lower cap having an open end; two or more pieces of propellant housed within the lower cap; and an upper cap matable with the lower cap at the open end via an interference fit, an adhesive, a wax, a threaded interface, or a combination thereof, wherein mating the lower cap and the upper cap secures the two or more pieces of propellant within the propellant container for use within the perforating gun, wherein a rate of combustion of at least one of the two or more pieces of propellant increases at a greater than linear rate and a surface area of the at least one of the two or more pieces of propellant increases during combustion until consumed by the combustion, and wherein at least one of the two or more pieces of propellant does not combust at an increasing rate after being ignited.
