Drilling fluids control mechanisms

The only iron-based chemicals currently used as scavengers in drilling fluids are the iron oxides, which are insoluble in both water and mud. Reaction mechanisms between iron oxides and soluble sulfides that cause the formation of various iron-sulfur compounds may involve changes in oxidation state, precipitations, or combinations of both. Transformation of iron-sulfide crystalline structure with time also may occur. Chemical literature points out system variables that control reaction... [Pg.467]
