This report documents laboratory studies that display the potential of the new iron sulfide treatment that, instead of preventing the formation of the scale, allows a dispersed iron sulfide to form that is both water wet and deactivated. Evidence has been provided that shows how the treatment keeps the particle size small so that is unlikely to associate and deposit in production systems. The mechanism of control is and the parameters that control the performance are discussed. The dispersant facilitates the transport of the scale with the produced water but prevents the FeS from forming pads at water-oil interfaces. Results from a limited field trial demonstrate the success of the treatment in the preventing the formation of pads in a primary separator, and solids deposition in a heater treater.
