ported sub 100 with said first end 102a and said second end 102b at
its ends.
[0024] One example of a system for mitigating the risks of working
with a perforating gun can be found in U.S. Pat. No. 745,830
(incorporated here by reference), which discloses a system for
working on perforating guns.
[0025] In one embodiment, said offset angle 208 can comprise a
range of 15-60 degrees to allow easy access to said electrical
channel 202.
[0026] FIGS. 2C and 2D comprise elevated cross-section views of
said titled ported sub 100, as labeled on FIG. 2A.
