API Spec 19G2

This specification provides requirements for subsurface flow-control devices used in side-pocket mandrels intended for use in the worldwide petroleum and natural gas industry. This specification addresses injection-pressure- operated (IPO), production-pressure-operated (PPO), pilot, orifice, and dummy flow-control devices. This includes requirements for specifying, selecting, designing, manufacturing, quality control, testing, and preparation for the shipping of flow-control devices. Additionally, it includes information regarding performance testing and calibration requirements.

The installation and retrieval of flow-control devices is outside the scope of this specification. Additionally, this specification is not applicable to flow-control devices used in center-set mandrels or with tubing-retrievable applications.

This specification does not include requirements for side-pocket mandrels, running, pulling, kick-over tools, and latches that may or may not be covered in other API documents. Reconditioning of used flow-control devices is outside of the scope of this specification.
