7 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 Typhoon Valve illustration

8 Typhoon Technology Evolution 2004 A B C D E F -Six different test rigs, -small and full scale valves, -two and three phase flows, -realistic test conditions

9 Typhoon Technology Small scale crude oil tests 11 North Sea crudes have been tested: Systematic positive effect on produced water

10 Prototype produced water test Flow rig in Typhonix Laboratory Produced water test rig Three North Sea crudes - Low dp (max 5 bar) - Low [oil] - No gas Typhoon Valve and standard valve

11 Droplet Size [µm] Prototype produced water test Dv(50) Crudes - Max dp Typhoon Standard Norne Valhall Goliat Field a Field b Field c Conlusions Typhoon Valve gives larger oil droplets Largest effect on the smallest oil droplets Limited effect at small inlet oil droplet size

15 OiW [ppm] Results: Effect of dp 700,0 OiW as function of pressure drop (constant gas/liquid rate, water cut 80 % and valve opening) 600,0 Standard Typhoon 500,0 400,0 Typhoon 300,0 Standard 4.2 bar dp 200,0 100,0 0,0 4,2 6,5 9 Pressure drop [bar]

16 OiW [ppm] Results: Effect of GLR OiW as function of gas/liquid ratio Constant pressure drop, valve opening and water cut 80% Gas/liquid ratio Typhoon Standard

18 Conclusions 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 Standard Typhoon

19 Demo 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 host benefits Test technology for increased and cleaner production First hand knowledge and early access to the technology Learn more about own process Pilot project /11

20 Demo 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
