Separation Systems

ProductionImprovements



Production Impro vementsOur capabilities in trouble-

shooting and debottlenecking

separation systems can help

you maximize the throughput

and efficiency of existing

production trains and reduce

the size of new separation

equipment. This typically

results in problem-free opera-tion, a reduction in capital and

operational expenditure and –

in many cases – an increase

in profits.



Benefits Maximize gas production Maximize oil production Minimize operational issues Minimize production problems Reduce impact of solids

Minimize use of chemicals

Separation Systems The separation company major oil companies go

to with their most challenging projects. Maximum return on investment through extensive

experience and know-how. The only separation company with a proven track

record with inline separation equipment.

The leading company in subsea separation. Develops out-of-the-box solutions for the separationchallenges of tomorrow.

The need for productionimprovements – thechallengesYou can unlock the potential of your existing facility using

Separation technologies if you want to: handle decreasing wellhead pressure and increased

water production tie back subsea production to existing facilities handle space and weight restrictions in existing

facilities overcome production loss due to lack of efficiency of

existing equipment enhance oil recovery by using new modes of operation changing gas/oil ratio for late-life operations need for improved water quality.

Unlock the potentialof existing facilities



Increase in production capacity ofexisting installationsOur patented inline and internal separation technologies resolve these challenges.

We were the first company worldwide to install a subseaseparation unit. This opens up unlimited opportunities forincreasing oil recovery from brown fields. Today all theprojects worldwide that include subsea processing useFMC technology.

With our inline equipment the efficiency of facilitiescan be improved even if there is no space for additional

separators or when vessel entry is not possible or notpermitted.

Integrated InLine SystemsRetrofit internals

InLine SolutionsSubsea separation

Retrofit internals: our state-of-the-art internals providemaximum separation efficiency. Our internals are custom-made for each application, fabricated according to thehighest quality standards, updated to the latest state oftechnology and can always be installed without hot workat the pressure vessel.

For new-build applications our technologies can be com-

bined in highly efficient, very compact separation systems.These systems can be installed topsides and subsea.

Our approachWe first identify the needs and options for productionimprovement and undertake trouble-shooting and therequired analyses and CFD studies. The resulting reportcontains recommendations and a proposal for thetechnology needed, including costs and expectedinstallation time.

If the proposed solution is based on new technology,we can test it at the customer’s request, using our in-housetest system. In most cases we can run a full-scale test athigh pressures and with real liquids.

Case Study:Increased Gas ThroughputWe succeeded in tripling production, simply by selectingthe appropriate internals. The improvements paid forthemselves in less than a day.

Increased production:– Compressor vibration causing major maintenance

shutdowns and costs – Platform design flow rate 180 MMSCFD – Pre-retrofit production limited to 80 - 90 MMSCFD:

only with leaner wells – Post-retrofit production in excess of 270 MMSCFD:

richer wells can also be used Increased revenue:

– (270 - 90) MMSCFD x USD 3,000– = USD 540,000 per day

– Limited shutdown time – No hot work required Cost of the internals: approximately USD 300,000

Case study:Vesselfrikk – InLineproduction improvement

Using Inline for flow assurance to improve the oil recoveryfrom a well. In the existing situation oil was produced on the

A platform and transported to the B platform. Due to the mixed

phase flow regime in hoses between platforms the flow pressure

drop was 6 bar.

Before

After

A Flowsplitter was added and half the hoses are used for liquid and half are used for gas,

allowing the pressure drop to be reduced, which in turn allows more oil to be recovered.

The pressure drop across the interconnecting hoses was reduced by 2 bar.

Tordis

Tordis is recognized as one of the most important break-through technology milestones for subsea in recent years.

On stream since 1994Well head pressure decreasing and water cut increasing

Tordis IOR (Increased Oil Recovery) investment isapproximately US$200 million including SSS (SubseaSeparation Station) and GullFaks C modification.

Increased recovery anticipated to be from 49 % to55 % that is equivalent to 35 million barrels of oil.60 % increase generated by the SSS

Approximately US$950 million increased revenue@ 50 USD/barrel

10 km tie-back to Gullfaks C

The InLine- DeGasser, DeSander, PhaseSplitter, DeWaterer and DeLiquidiser are patented by Statoil and FMC have exclusive worldwide

license to sell this technology.
