Field experiences• Shear break droplets • Shear tightens emulsions• Main droplet break-up in choke

valves• Increased choking → smaller

droplets → tighter emulsions

- Choke and control valves degrades oil and water quality

Standard plug/cage valve

Typhoon Valve challenges the cause – not the effect

Typhoon Technology

Valve features

• Plug/cage

• Swirling flow

• Low shear/turbulence

• Large cage flow area

Process benefits

• Less emulsification

• Improved separation

• Less OiW

• Less WiO

• Less chemicals

• Less blocking

Process disadvantages

• Possibly increased size and weight

Evolution 2004 →

-Six different test rigs, -small and full scale valves, -two and three phase flows, -realistic test conditions

Small scale crude oil tests

• 11 North Sea crudes have been tested: Systematic positive effect on produced water

The prototype tests have verified the Typhoon Valve technology:

Conducted at realistic fluid and flow conditions

Both water and oil quality are improved

Impressive reduction in OiW at 50 to 90% WC

Typhoon Valve typically reduces OiW by 60-90%

High effect also at low dP

Increased positive effect at more closed valves

Robust technology not depending on specific geometries

The benefits are maintained across dP and GLR ranges

Conclusions

Standard Typhoon

Demo 2000 - Pilot test

We are searching pilot candidates!!

Objective

Demonstrate that Typhoon Valve optimise oil-water separation

Improve the water quality

Improve the oil quality

Pilot project 2009-2010/11Pilot host benefits

• Test technology for increased and cleaner production

• First hand knowledge and early access to the technology

• Learn more about own process

Demo 2000 - Pilot test

Pilot candidates are

Choke valves on wells with OiW challenge

Water cut above 60%

Pressure drop above 4-5 bar

Pilot test: Duration 4-10 days – need availability of test separator, probably no reconstruction

The Typhoon technology is realized because of
