| abstract | "Compositions and Method for the Treatment of Hydrogen Sulfide and Prevention of the Settlement of the Precipitate in an Environmentally Responsible Drilling and Sealing Fluid" The present invention relates to an environmentally responsible iron chelation additive and method for the removal of sulfide hydrogen or sulfide ions from sealing and drilling fluids and prevention of settling of precipitates. iron chelating agents selected from the group consisting of ferrous lactate, ferrous gluconate, ferrous bis glycinate, ferrous citrate, ferrous acetate, ferrous fumarate, ferrous succinate, ferrous saccharate, ferrous tartrate, ferrous glycate sulfate, ferrous glutamate, ferrous ascorbate ferrous or a combination thereof may be used. when fluids are oil based, iron chelating agents are added to the water phase of an emulsion and the emulsion is added to the fluid. Viscosants can also be added to the drilling fluid with the emulsion. |
