Specific Challenge

Scale removal for an offshore oil producer

Challenge

  • Well A - Offshore oil producer, casedhole and perforated completion
  • Low pressure, heavy oil (11°API), producing through ESP
  • Calcium sulfate scale inside the ESP pump (increased operating temperatures of the pump)
  • XRD analysis revealed >90% CaSO₄
  • Typically, ESP’s had been damaged leading to well maintenance and intervention costs, lost time, and deferred oil production for this field

Solution

  • 25-bbl pill of HalKleen™ G scale dissolver 
  • Pumped through the production tubing and allowed to soak for 1 hour on the ESP pump 

Result

  • ESP motor temperature decreased by 13ºC
  • Well is currently producing at expected rates
