26 Years & Counting!
A Reliable Presence during Changing Times.
As operator demands have evolved and as some
of the world’s most remote fields have entered
production, one requirement has remained
constant - the need for operators to access
reliable and real-time downhole temperature and
pressure information from the reservoir.
And one company stand out of the crowd having
delivered this information reliably and accurately
for the past 26 years – Roxar Flow Measurement.

THE FACILITIES REGULATIONS CHAPTER VIII DRILLING AND WELL SYSTEMS Section 48 Well barriers
REGULATIONS RELATING TO DESIGN AND OUTFITTING OF FACILITIES, ETC. IN THE PETROLEUM ACTIVITIES (THE
FACILITIES REGULATIONS)
(Last amended 23 December 2013, cf. page 5)
“Well barriers shall be designed such that well integrity is ensured and the barrier functions are
safeguarded during the well's lifetime.
Well barriers shall be designed such that unintended well influx and outflow to the external
environment is prevented, and such that they do not hinder well activities.
When a production well is temporarily abandoned without a completion string, at least two qualified
and independent barriers shall be present.
When a well is temporarily or permanently abandoned, the barriers shall be designed such that they
take into account well integrity for the longest period of time the well is expected to be abandoned.
When plugging wells, it shall be possible to cut the casings without harming the surroundings.
The well barriers shall be designed such that their performance can be verified”
[File Name or Event] Emerson Confidential 27-Jun-01, Slide 24
Section 54 Christmas tree and wellhead
“Christmas trees and wellheads shall be designed such that prudent well control can be performed
through recovery, workover and well intervention.
The christmas tree shall have at least two main valves, and at least one of them shall be automatic.
In the case of hydrocarbon flow in the annulus, the closest outer annulus shall be pressure-
monitored.”
