Embodiment Construction
[0024]Reference will now be made in detail to various embodiments. Each example is provided by way of explanation, and is not meant as a limitation and does not constitute a definition of all possible embodiments.
[0025]As used herein, the term “non-axisymmetric” means not axisymmetric as defined hereinabove, and includes non-circular and non-conical shapes. As an example, and with reference to the shaped charge found in FIG. 2, the distance between a point on the periphery of the body from the central axis y-y found at L3 is not equal to the distance found at L4. As used herein, the term “multiple” means more than one.
[0026]A non-axisymmetric shaped charge is generally described herein, having particular use in conjunction with a perforating gun assembly. In an embodiment, the non-axisymmetric shaped charge is configured for use with a perforating gun assembly, in particular for oilfield or gas well drilling or completions. The non-axisymmetric shaped charge provides multiple initia...
