Included are the requirements for design, design validation,
manufacturing, functional evaluation, repair, redress, handling and
storage. Subsurface barrier valves provide a means of isolating the
formation or creating a barrier in the tubular to facilitate the
performance of pre- and/or post-production/inje
The subsurface barrier valve is not designed as an emergency or fail-safe flow controlling safety device.
