API Spec 19OH-2018 pdf free download.Openhole Isolation Equipment.
1 Scope This Specification covers requirements and guidelines for openhole isolation equipment and bridge plugs as defined herein. Openhole isolation equipment includes swellable packers, inflatable packers, expandable packers, and openhole packers that are designed for use in the petroleum and natural gas industries. This Specification provides requirements for design verification, design validation, manufacturing, quality, shipping, handling and storage, and related supporting topics. Included within this Specification are four Annexes, of them, B and C are normative, and A and D are informative. Requirements for the end connections to the well conduit are not included in this Specification. Also not covered are downhole anchoring devices (see API 1 1 D1 ); cup style packers; and requirements for the application, installation, and use of openhole isolation equipment. Equipment and technology that are covered by other API specifications and standards are exempted from this specification, such as: — production packers, — liner hanger systems, — service tools, — test tool packers. Repairs, remanufacturing, and redress are excluded from this Specification. 2 Normative References The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and Definitions For the purposes of this document, the terms and definitions given in API Q1 and the following apply. 3.1 assembly Product comprised of more than one component. 3.2 base elastomer An elastomer family of materials with common property limits such as HNBR, FKM, EPDM. 3.3 base elastomer formulation A base elastomer mixed with additives to achieve physical properties that enhance performance. 3.4 bridge plug Mechanical device used for blocking fluid (liquid or gas) communication within a conduit when installed (not installed in a design receptacle or conduit). 3.5 component An individual part of an assembly. 3.6 conduit Casing, tubing or liner, metallic, or nonmetallic. 3.7 design margin Ratio of the material yield stress divided by the actual design stress in a given component. NOTE Design margins account for a level of reduced performance capability to compensate for uncertainties in the loading (applied stress) and intrinsic variation in the mechanical properties such as yield strength, ultimate strength, endurance strength, modulus of elasticity that have distribution about their mean value.
3.20 openhole A wellbore with no casing or liner in place across the formation surfaces. 3.21 openhole mechanical packer Downhole device designed to isolate fluids in the annular space between a conduit and the openhole that is activated (expanded) by the application of force to an integral mechanism. 3.22 operating temperature range Specified range of temperature fluctuation over which the product is designed to operate. 3.23 packer Device with a packing element, not installed in a designed receptacle, used for blocking fluid (liquid or gas) communication through the annular space between conduits by sealing the space between them. 3.24 packing element External compliant sealing device on a packer that provides isolation of fluid communication through the annular space between the conduit and openhole. 3.25 packer mandrel Tubular component(s) within a packer that contain the end connections and provide a conduit through the packer. 3.26 product assembly The completed device that includes the necessary components to perform the designed functions. 3.27 qualified person Individual with characteristics or abilities gained through training, experience, or both, as measured against established requirements, such as standards or tests, that enable the individual to perform a required function effectively. 3.28 scaling The ability to validate a design by referencing the design validation conducted on a representative design of the same product type and family. 3.29 setting method The design methodology and tools necessary to activate the packer to its fully implemented condition. 3.30 substantive change Change to the design or components within the design, identified by the supplier/manufacturer, that may affect the performance of the product in the intended service condition.
