It will also be appreciated that such development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the field of the appropriate art having the benefit of this disclosure. Accordingly, the claims appended hereto are not intended to be limited by the disclosed embodiments, but are to be accorded their widest scope consistent with the principles and features disclosed herein.

FIGS. 1A, 1B and 1C illustrate a perspective overview, and a perspective first and second side view of a tilted ported sub 100. In one embodiment, said tilted ported sub 100 can comprise a substantially cylindrical shape. In one embodiment, said tilted ported sub 100 can comprise a first end 102a, a second end 102b, a tilted port 104, a first end threading 106a at said first end 102a, a second end threading 106b at said second end 102b, a first end ribs 108a, a second end ribs 108b, a one or more slots and a center portion 112. In one embodiment, said one or more slots can comprise an upper first end slot 110a, a lower first end slot 112a, an upper second end slot 110b and a lower second end slot 112b. In one embodiment, said one or more slots can comprise an optional feature for said titled ported sub 100. In one embodiment, said titled ported sub 100 can comprise a first bore 114a in said first end 102a and a second bore 114b in said second end 102b. In one embodiment, said tilted port 104 can comprise an O-ring groove 116.

In one embodiment, said titled ported sub 100 can be used in sequence with a one or more guns (not illustrated, but known in the art), as is known in the art. Said titled ported sub 100 can comprise industry standard features capable of attaching to common assemblies. In one embodiment, said titled ported sub 100 can receive a one or more wires for detonating a one or more guns (as known in the art) which can be attached to said titled ported sub 100 at either or both of said first end 102a and/or said second end 102b. In one embodiment, said tilted port 104 can be known as an angled griz-gun port.

FIGS. 2A and 2B illustrate an elevated front view and an elevated cross-section front view of said titled ported sub 100. In one embodiment, said titled ported sub 100 can comprise an electrical channel 202. In one embodiment, said electrical channel 202 can be a fluid channel between said first bore 114a and said second bore 114b with said tilted port 104 allowing access to said electrical channel 202 between said first bore 114a and said second bore 114b. In one embodiment, said tilted port 104 can comprise a seal 204, a thread lock 206, and said O-ring groove 116. In one embodiment, said tilted port 104 can be useful for providing easier access to said electrical channel 202. In one embodiment, said seal 204 can wrap around said tilted port 104. In one embodiment, said O-ring groove 116 can receive an O-ring (not illustrated here) which can be useful for protecting said titled ported sub 100 in the harsh climate in which it is employed.
