1. SAGD (De-Oiling) Solutions

2. SAGD Produced Fluid Separation requirements: Sand Removal: continuous, batch process, in tank separators Oil Removal: cyclones, induced gas flotation, filtration Gas Removal: cyclones, large vessels, high pressure cyclones Question #1 – What level of water quality is required? (How Clean is Clean?) Question #2 – What does it cost to get the water quality required? Question #3 – What level of water quality can I get within the allotted budget? Produced Water Treatment Equipment

6. Produced Water Separation Capabilities Gravity Separation Two Phase/Three Phase Separators: 1000’s of ppm oil in water, % oil in water CPI/API Separators: inlet 5,000 - 20,000 ppm - removal efficiency 90% - 500 - 2000 ppm outlet Cyclonic Separation De-oiling Hydrocyclones: 2,000-5,000 ppm inlet – removal efficiency 90% - 200-500 ppm outlet Pressurized Oil/Water Separation Induced Gas Flotation: 200-500 ppm inlet – removal efficiency 90% - 20-50 ppm outlet Pressure Filtration – Granular Media/Depth Filtration and Surface Filtration Nut Shell Filter: 20-50 ppm inlet – removal efficiency 90% - 2-5 ppm outlet Cartridge/Bag filter: 2-5 ppm inlet – removal efficiency 90% - less than 1 ppm – or absolute micron cut off

7. Produced Fluid Separation Requirements Off Shore Disposal or Injection Disposal: GOM 29 mg/L (ppm), spikes to 40 mg/L (ppm) – everywhere else in the world – 15 ppm and lower On Shore Water Management Disposal Wells: what is required to make sure they do not plug the injection well – completely dependent on the injection formation – 50 ppm? – 20 ppm? Less for tighter formations. Water Flood for Oil Recovery: again water quality to assure the injection well does not get plugged such that long term oil production is affected – 20 ppm or less usually required Steam Flood for Enhanced Oil Recovery: pressure and temperature for enhanced oil recovery – protecting softeners and steam generators – 2 ppm or less usually required

29. CFD Study of Mixing in Cylindrical Tanks Performed for R & D 1057 Dr. Binxin Wu Sr. CFD Research Engineer Philadelphia Mixing Solutions 1221E. Main St., Palmyra, PA 17078 Phone: 717-832-8857 Fax: 717-832-1740 www.philamixers.com Mar. 13, 2013

30. Objectives The objectives of this CFD analysis are to: 1. Develop a CFD model to predict the mixing flow patterns in cylindrical tanks mixed by a mechanical impeller and a pump, respectively, and 2. Qualitatively and quantitatively identify the flow patterns.
