Abrégé

A propellant container for a perforating gun includes a lower cap, one or more pieces of propellant positioned within the lower cap, wherein at least one of the one or more pieces of propellant defines one or more through-holes, and an upper cap matable with the lower cap to secure the one or more pieces of propellant within the lower cap. A filler material is present within interstitial spaces between the one or more pieces of propellant.

Classes IPC  ?

• E21B 43/117 - Perforateurs à charge profilée
• E21B 43/114 - Perforateurs utilisant l'action directe d'un fluide, p. ex. jets abrasifs

Abrégé

A method of creating and finishing perforations in a hydrocarbon well having a well wall that includes causing a high velocity jet of a material to shoot into the well wall, thereby creating a perforation in the well wall. The method further includes introducing a gas blast into the perforation, for a blast time duration, the gas blast creating an increasing pressure at the perforation until a maximum pressure is reached; and allowing the pressure of the gas blast to undergo a period of rapid decline to a level of less than 50% of the maximum pressure.

Abrégé

A low profile high energy gas fracturing device, comprising a closed steel tube having a uniform wall thickness, except for having thinned areas that are designed to rupture when subjected to pressure greater than a predetermined level. Propellant is packed into the said steel tube sufficient to create high pressure above said predetermined level, when ignited. Finally, an ignition mechanism passes through said tube, to ignite the propellant.
