Outline
• History of Gas-lift Standards
• Adding V0/F0 requirements and why
• Adding V00/F00 requirements and why
• Conclusion
ISO API 11V1
•Original document released
June 1, 1988
•Covered only Valves
•Revised document released
February 1, 1995
•Added side-pocket mandrels

ISO 17078-2
•Original document released
December 15, 2007
•Specifically did not address
barrier check flow control valves
(FCD)
•Removed the requirements for
conventional (tubing retrievable
FCD)
•Added three design validation
(V3, V2 & V1)
•Added three product functional
test requirements (F3, F2 & F1)

API 19G2
•Original document released
December 1, 2010
•Adopt back from ISO 17078-2
•Changes to V3 and addition of
Monogram annex
•As with ISO 17078-2,
specifically did not address
barrier check valves
•In conjunction with API 19G1,
API 19G2 replaced API 11V1,
July 2012
•Dual branded document

Statoil TR 2385
•Original document released as
WR 5354 on November 1, 2009
•Rereleased as TR 2385 on April
4, 2011
•Updated to current version
March 26, 2012
•Specifically addresses barrier
check valves
•Specifically requires valves to
also be qualified per ISO 17078-2
V1 & F1
•Multiple manufactures have
completed qualification to Statoil
requirements

Driving the V0/F0 Development
• Since the original release much has changed
relating to gas-lift flow control devices
– Existing ISO/API requirements do not focus on barrier
requirements
– Release of the Statoil barrier qualification requirements
– Multiple manufactures have completed testing to Statoil
requirements
– Need to standardize on barrier requirements world wide
Feb. 4 – 8. 2013 2013 Gas-Lift Workshop
8
Driving the V00/F00 Development
• Deep water requirements
– Bellows life cycle testing
• Max rated pressure and temperature
– Improved barrier check qualification
• Gas flow rate testing
• Cyclical loading
– Improved elastomer testing
Feb. 4 – 8. 2013 2013 Gas-Lift Workshop

• ISO Oilfield process
– ISO oilfield process has stopped
– ISO oilfield standards are now stagnant and
not being improved or corrected
– ISO/API are not work together
• Not sharing documents – no adopt back
• No mechanism for updating the
improvements/corrections to the ISO
document
Train Wreck – ISO/API Process

History of Gas-lift Standards
• Since the original release much has changed
relating to gas-lift flow control devices in barrier
applications due to the Statoil qualification
requirements. The soon to be released version
of the API 19G2 document will include the testing
requirements as established by Statoil and
adopted as the defacto industry barrier
requirement standard. Out of this effort, it
became clear, an even more stringent level of
design validation and product functional testing
is required for Deep Gulf of Mexico applications
in the API 19G2 Standards.
