Closure member and encapsulated slotted shaped charge with closure member

An encapsulated slotted shaped charge comprising:

• a rectangular case having a cavity, a closed portion and an open portion;
• and
• a shaped charge closure member comprising
• a body having a hollow interior and comprising:
• a closed upper portion,
• a lower portion opposite the closed upper portion, the lower portion defining an area that is larger than the closed upper portion,
• a first planar side wall extending between the closed upper portion and the lower portion,
• a second planar side wall spaced apart from the first planar side wall, and extending between the closed upper portion and the lower portion,
• a front wall extending between the first planar side wall and the second planar side wall, and
• a back wall opposite and spaced apart from the front wall, and extending between the first planar side wall and the second planar side wall,
• wherein a surface of the closed upper portion extends from an upper portion of the first planar side wall to an upper portion of the second planar side wall and has a curved profile therebetween, wherein the curved profile includes a portion of the surface extending in a direction away from the upper portions of the first planar side wall and the second planar side wall.

An exposed perforating gun system comprising:

• a shaped charge carrier;
• an encapsulated slotted shaped charge mechanically fixated in the shaped charge carrier, the encapsulated slotted shaped charge comprising:
• a rectangular case having a cavity, a closed portion and an open portion, and
• a shaped charge closure member comprising:
• a body having a hollow interior and comprising:
• a closed upper portion,
• a lower portion opposite the closed upper portion,
• a first planar side wall extending between the closed upper portion and the lower portion,
• a second planar side wall spaced apart from the first planar side wall, and extending between the closed upper portion and the lower portion,
• a front wall extending between the first planar side wall and the second planar side wall, and
• a back wall opposite and spaced apart from the front wall, and extending between the first planar side wall and the second planar side wall,
• wherein a surface of the closed upper portion extends from an upper portion of the first planar side wall to an upper portion of the second planar side wall and has a curved profile therebetween, wherein the curved profile includes a portion of the surface extending in a direction away from the upper portions of the first planar side wall and the second planar side wall.
