Example of scaling in piping
Mixing injected and formation water may result insulfate/barium scaling
• Limit formation of barium and strontium saltsin injection well, piping and equipment
• Production well control• Radioactive scaling or NORM• Allows anti-scalants to perform on full
effectivenessReservoir Souring
• Limit well souring at water breakthrough as NFremoves all contaminants grater than 1/1000thsof a micron
• Reduce environmental safety & health issuesby less chemical injection
• Lower level of hardness (magnesium/calciumions)

Benefits
• One of the original Dow/Marathonmembrane suppliers – having 17 years ofexperience
• Compact system design• Single source turnkey supply
Scope of Supply• Dow SR membranes (external
technology)• SRU train with valves/instruments• Cleaning in Place (CIP) package skid• Feed booster pumps• Loose skids or module with pre-
treatment
Treatment
• Removes sulfate from seawater toprevent scaling caused bybarium/strontium in the formation water
• Nano-filtration spiral wound membranesremoves sulphate ions down to 15 ppm
• Reduces risk of souring in the reservoir
