API SPEC 19ICV

Anotace textu normy API SPEC 19ICV :

This specification provides the requirements for downhole interval control valves (ICV) as they are defined herein for use in the petroleum and natural gas industries. Included are the minimum requirements for a functional specification, design verification, design validation of performance ratings, manufacturing, functional evaluations, shipping, handling, and storage. Also included are requirements for downhole control modules which are necessary for the defined operations of the ICV.ICVs conforming to this specification are not designated as well safety devices.This specification does not include any additional requirements for high-pressure high-temperature (HPHT) environments with a pressure rating greater than 103.4 MPa (15,000 psi) or with a temperature rating greater than 177 °C (350 °F).This specification does not cover validation testing with gas medium.This specification does not cover applications, installation, operation, and maintenance. Control systems components for the ICV which are designated for positions above the tubing hanger are not included.Also not included are products covered under other API specifications and the following products: remotely operated gas lift valves, inflow control devices (ICD) and autonomous ICDs, through tubing mechanically operated sliding sleeves, valves designed to function a single time, well-condition-activated valves or well test tools. Also not included are secondary tools, control conduits including the connections, and reservoir monitoring devices not critical to the operation of the ICV. End connections of the ICV to the well conduit are not included.  See more
