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.

Superior cooperation

Roxar are cooperating with Superior Energy

Services with intentions to:

• Jointly promote each others product portfolio

• Jointly develop products and services to

enable customers to select most suitable

lower completion systems to their

applications

• Engineering of combined solutions that would

provide customers with improved functionality,

reduced costs or lower risk exposure.

• Phase one sensor prototype ready for test!

Metrol

Features and Benefits

•Operates with any brand of DST string

•Communicates over long distances, allowing

gauges to be positioned nearer the formations

•No wet connections or complicated latch,

unaffected by sand or debris

•Possible to retrieve data if the test string

becomes stuck in the hole

•One second SRO sample rate data

•Reprogram gauges from above the valve

requires less equipment, reducing freight costs

•Can “Talk” to multiple gauges in multiple

locations


Solution

Interface to Metrol

Advantage

•Remove 4-6 relay stations

•Add Roxar capability to adress Multilaterals

•Open to new markets

Development

•Use existing RODIM and WiPT technology

•Interface to Metrol acoustic link

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”


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.”
