Core Standard
Energy Infrastructure Context Guides
Context Guides apply IQC1 to specific energy-infrastructure systems and real operating conditions.
Production Function Realization, Reservoir Interfaces, and Evidence
Applies the IQI Core Standard to onshore natural gas production zones, including wells, surface facilities, Quality Factors, Indicators, and bounded Quality Claims.
Transportation Function Realization, Route Continuity, and integrity
Applies the IQI Core Standard to onshore natural gas main pipeline transportation infrastructure, including pressure, compression, reliability, interfaces, Indicators, and bounded Quality Claims.
Delivery Function Realization, Pressure Control, and Service Interfaces
Applies the IQI Core Standard to natural gas local distribution networks, including pressure regulation, service lines, public proximity, reliability, Indicators, and bounded Quality Claims.
Storage Function Realization, Deliverability, Contaiment, and Cycling
Applies the IQI Core Standard to underground natural gas storage infrastructure, including injection/withdrawal, cushion gas, reservoir or cavern integrity, Indicators, and bounded Quality Claims.
Cryogenic Contaiment, transfer, Send-Out, and Interface Control
Applies the IQI Core Standard to LNG infrastructure, including liquefaction/regasification systems, cryogenic storage tanks, transfer and loading interfaces, Quality Factors, Indicators, and bounded Quality Claims.
About - Energy Infrastructure Quality in Practice
IQI is a volunteer-run public initiative focused on making energy infrastructure quality visible, understandable, and evidence-supported.
Its standards, vocabularies, Context Guides, and other resources are voluntary and non-regulatory.
They do not constitute engineering supervision, regulatory enforcement, certification, legal compliance, or approval of any energy-infrastructure asset or Quality Claim.
IQI is an applied initiative under the Whole-Quality Institute (WQI).
