CHEMICAL INJECTION BHA

The LiMARĀ® Chemical Injection BHA comprises of a reservoir, pump and series of scrapers to target specific areas of deposit build up in the wellbore.

When an obstruction is encountered the pump and scraper mechanisms are activated by reciprocating the work-string at the hold up depth. Solvents or chemicals are then discharged to various ports and scraper mechanisms in the BHA.
