1 Scope This specifcation provides the requirements for subsurface completion isolation (barrier) valves (SCIV) and related equipment as they are defned 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 fow 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 fow-controlling safety device. This specifcation 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 17078, ISO 16070, ISO 14310, ISO 10432, ISO 10423, and the following products: downhole chokes, wellhead plugs, sliding sleeves, casing-mounted fow-control valves, injection valves, well-condition-activated valves, or drill-stem test tools. This specifcation 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.

Terms? and? Defnitions For the purposes of this document, the terms and defnitions given in ISO 9000 and the following apply. 3.1 assembly (noun) Product comprised of more than one component. 3.2 ambient temperature Prevailing temperature at test site. 3.3 base design Design of a specifed size, type, and model of SCIV that has passed the requirements of Annex B and meets the requirements of this specifcation. 3.4 blockage barrier Obstacle or impediment to fow and/or pressure. 3.5 casing Pipe extending from the surface and intended to line the walls of a drilled well. 3.6 casing-mounted? fow-control? valves Downhole valves permanently installed as a component of the casing or liner (pipe not extending from the sur- face and intended to line the walls of a drilled well). 3.7 city water Water that is provided by the local water utility system, which may include inhibitors.
3.8 closing mechanism Device designed to block or impede fow at a designated point when closed. 3.9 common hardware Non-traceable nuts, bolts, washers, screws, and spacers. 3.10 design margin Ratio of the material minimum yield stress divided by the actual design stress in a component at the rated con- ditions. 3.11 design validation Process of proving a design by testing to demonstrate conformity of the product to design requirements. 3.12 design? verifcation Process of examining the result of a given design or development activity to determine conformity with specifed requirements. 3.13 downhole choke Downhole device used to restrict fow rates through its ID and not intended to seal as a barrier. 3.14 drift diameter Minimum ID of a SCIV, expressed as the OD of the drift bar used during assembly verifcation. 3.15 drill-stem test tools Downhole tools temporarily set in place for the purpose of evaluating the production potential of the chosen formation.
