Abstract:
An apparatus and method for specialized shaped charges that perforate similar sized diameter holes regardless of the fluid gaps between the shaped charge and the casing wall. Shaped charges having three conical or frusto-conical liner sections are disclosed, where the apex liner section has a larger conical angle than the outer liner section are disclosed.

Claim (Index 4):
The method of  claim 1 , wherein the shaped charge comprises a case, explosive material, and a liner further comprising an axis, a first section having a substantially conical shape, a first inner surface, a lowermost apex, and a first conical angle respective to the first inner surface, a second section having a substantially frusto-conical shape, a second inner surface, and a second conical angle respective to the second inner surface, a third section having a substantially frusto-conical shape, a third inner surface, a top surface perpendicular to the axis, and a third conical angle respective to the third inner surface, the first section, second section and third section being axially aligned about the axis, the second conical angle being larger than the first conical angle, the second conical angle being larger than the third conical angle and the liner having a total height measured from the lowermost apex of the first section along the axis to a plane perpendicular to the top surface.
