WellProtek® is FO>'s line of API-16A licensed* annular packing units. All units are Factory Acceptance Tested (FAT) before shipment, stamped with the official API Monogram® and shipped with full documentation in compliance with API-16A requirements.
Our WellProtek® units utilize proprietary elastomers, products of FO>'s material development and engineering expertise. Through extensive testing, our compounds show superior Rapid Gas Decompression (RGD) resistance and extended durability and performance.
Freudenberg Oil & Gas Technologies is a global provider of innovative sealing solutions and differentiated products to the upstream oil & gas industry, including metal-to-metal, advanced thermoplastic and elastomeric sealing solutions. Our commitment and dedication to develop market leading technologies and supported with in-house product verification testing, is featured with the successful introduction of the WellProtek® API-16A licensed and 16AR compliant annular units.
Design verification performance testing in accordance with API-16A requirements were third party witnessed and included:
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.
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.
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.
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).
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.
