1 Scope This specification provides the requirements for subsurface completion isolation (barrier) valves (SCIV) 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 grades, quality levels, manufacturing, functional evaluation, repair, redress, handling, and storage. SCIVs provide a means of isolating the formation or creating a blockage in the tubular to facilitate the performance of pre- and/or post-production/injection operational activities in the well. Additional requirements for HPHT products are included in Annex I. When closed, the SCIV provides an obstacle or impediment to flow and/or pressure from above and/or below and a means of isolating the formation within a conduit. The SCIV is not designed as an emergency or fail-safe flow-controlling safety device. This specification does not cover installation and maintenance, control systems such as computer systems, and control conduits not integral to the SCIV. Also not included are products covered under ISO 1 7078, ISO 1 6070, ISO 1 431 0, ISO 1 0432, ISO 10423, and the following products: downhole chokes, wellhead plugs, sliding sleeves, casing-mounted flow-control valves, injection valves, well-condition-activated valves, or drill-stem test tools. This specification does not cover the end connections to the well conduit. 2 Normative References The following referenced documents are indispensable for the application of this document.
