Claim 30:
31. The port sub as claimed in claim 26, further comprising:
the degradation-promoting agent;
wherein:
the degradation-promoting agent and the control flow port flow controller are co-operatively configured such that:
while the control flow port sealing configuration is disposed in the sealing-effective configuration, the degradation-promoting agent is retained by the control flow port sealing configuration; and
in response to the transitioning of the control flow port flow controller from the closed configuration to the open configuration, the emplacement of the degradation-promoting agent in the degradation-effective communication with the standard flow port sealing configuration via the first end sealing surface and also via the second end sealing surface is established.
