WellProtek™ vs OEM Annular Packing Units

Tested to 115% of API fatigue test target*

Design verification performance testing in accordance with API-16A requirements were third party witnessed and included: 

  • Sealing characteristics testing

    This test determines the piston closing pressure necessary to maintain a seal as a function of wellbore pressures up to full rated working pressure of the blowout preventer.

  • Fatigue testing

    This test simulates closing and opening of the blowout preventer once per day. Testing simulates wellbore pressure testing from 200 psi to 300 psi once per week for one year of service.

  • Packer access testing

    This test determines the ability of the blowout preventer to undergo repeated packer changes without affecting operational characteristics. This test shall be accomplished by obtaining access to the packing unit and performing a wellbore pressure test every 20th packing unit access.

  • Stripping life testing

    This test determines the ability of the annular packing unit to maintain control of wellbore pressure while stripping drill pipe and tool joints through the closed packing unit without exceeding a leak rate of 4 liters/min. (1gal/min).

  • Temperature testing

    This test verifies the performance of non-metallic seals and molded sealing assemblies used as pressure-controlling and/or pressure-containing during exposure to low and high temperatures.

API-16A  Product Testing Requirements

* With the exception of stripping test, the acceptance criterion for all tests to verify pressure integrity was zero visible leakage.
