| titleOfInvention | Iron sulfide scale inhibition in an oil production system |
| abstract | A methods and compositions for inhibiting iron sulfide scale in an oil production system having a well in a hydrocarbon-bearing formation. The method includes the steps of: supplying an aqueous scale-inhibiting solution comprising a water-soluble metal compound and a scale inhibitor, the water-soluble metal compound comprising a metal selected from the group consisting of lead, zinc, and combinations of the same; and wherein the scale inhibitor comprises a compound selected from the group consisting of phosphino polymers, inorganic polyphosphinates, organic phosphate esters, organic phosphonates, organic aminophosphates, polyphosphonates, polycarboxylates, and combinations of the same; and injecting the aqueous scale-inhibiting solution through the well such that iron sulfide scale is inhibited in the oil production system. |
