 PYRISOL Dissolver Helps OMV Petrom Restore Full Production to ESP-Equipped Oil Well, Romania

Publication Date: 06/20/2017

An OMV Petrom well experienced severe scaling deposits in the tubing and ESP, diminishing output by 50% below original levels, while pressure and temperatures increased at the pump intake. Sample analysis revealed the scale was iron sulfide. Schlumberger consequently recommended PYRISOL iron sulfide scale dissolver. It is a unique alkaline dissolver designed to remove iron sulfide in a more safe and controlled manner without the liberation of H2S.

A total of 8 m2 of PYRISOL dissolver was circulated at 40 L/min for 24 hours. The estimated total scale removed was about 450–500 kg. ESP intake temperature and pressure returned to normal levels and production was fully restored.
