Reinjection
Automatic filtration for reinjection water where particulate control helps protect formations, pumps, and injection equipment.
When dealing with Reinjection, there are many water quality issues that must be addressed through filtration.
- Reinjection water can carry suspended solids, scale, corrosion products, and produced-water debris.
- Particulates can plug formations, damage pumps, and foul valves or injection equipment.
- Variable water quality requires filtration that can respond to changing solids load.
Conditions, Contaminants, and Considerations
Water sources may vary, but the primary water sources for Reinjection filtration are:
- Produced water
- Recycled water
- Surface water
- Injection water
In this application, water is usually filtered within the 50-300 micron range to remove contaminants like:
- Suspended solids
- Scale
- Corrosion products
- Sand
- Oilfield debris
Due to these constraints, certain design considerations must be made to accommodate variables that can interfere with the filtration process. Factors such as Formation sensitivity, Solids loading, Produced-water chemistry, Flow rate, Micron rating, and Flush waste handling must be accounted for to ensure reliable and efficient water filtration.
Benefits
Filtering the water before industrial or commercial use:
- Reduces particulate loading before reinjection.
- Protects pumps, valves, and injection infrastructure.
- Automatically cleans the screen during operation.
Relevant FAQs
Does the filter waste a lot of water while cleaning itself?
No, because of how quickly the filter cleans itself. Typical backwash water volume is as little as 10 gallons.
