Iron Sulfide Scale Dissolver
Keep the Production Clean
by Minimizing FeS
Iron sulfide can cause several issues in oil and gas production. For instance, it can plug filters, build up in tanks, shorten production-equipment life, and damage the formation. DOSAS offers formulated iron sulfide scale dissolver options to fit the needs of operators and help eliminate or control these issues.
Conventional iron sulfide solutions such as mineral and organic acids, oxidizers, acrolein, and Tetrakis Hydroxymethyl-Phosphonium Sulfate (THPS) pose different operation challenges for oil & gas producers. DoSolx™ 50 specialty formulation addresses these challenges by providing a non-corrosive and boosted dissolution to iron sulfide.
Efficient Dissolution of
Oil-Wet Iron Sulfides
DoSolx™ 50 is formulated with synergists to chemically modify the surface of the scale. It enhances the reactivity and efficiently dissolves the oil-wet scale deposits.
C/Co (%) represent the ratio of iron concentration in the spent dissolver to the initial amount of iron in the iron sulﬁde scale.
Low H2S Generation
H2S is generated during the reaction of common acid treatments which increases the corrosion rate of the tubes and causes health and safety problems because of its toxicity. DoSolx™ 50 released no H2S gas when iron sulfides are dissolved and is non-corrosive towards most encountered oilfield metallurgies.
