Clean Water Injection System

Clean Water Injection System

Clean Water Injection System

(OP)
My name is Brian and I am a first time intern this summer. I have been given a project that involves adressing some problems our water injection system has. We have close to 500 injection wells. Some of our lines are having problems due to line restriction from scale. I was wondering what the best way to remove this scale is? An acid flush can get fairly expensive and I did not know if there was such a thing as pigging water injection lines to remove the scale deposit. Any insight would be very helpful. Thanks a bunch.

RE: Clean Water Injection System

Are you mixing produced water and sea water for injection? If so you may need a unit for removing SO4-- (you propably already know this).

Best regards

Morten

To be honest I really have no experience in the field yet. I just changed majors less than a year ago so every piece of advice helps. Our sources are production water and also water from a nearby river. Right now we are treating the water with chlorine dioxide, but that began just 2 months ago. I wanted to know, the most cost efficient ways to clean out my lines and also if there is any other proactive steps to avoid scale deposits in the future.
