EN ISO 28781:2010 Petroleum and natural gas industries - Drilling and production equipment - Subsurface barrier valves and related equipment (ISO 28781:2010)
This International Standard provides the requirements for subsurface barrier valves and related equipment as they are defined herein for use in the petroleum and natural gas industries. 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/injection operational activities in the well.
