b) Solubility: The product should be soluble in fresh water and saline (3000-5000 ppm) produced Formation water in all proportions.
c) Compatibility : The product should be compatible with produced formation water, and various proprietary water treatment chemicals like Deoilers (cationic poly-electrolytes), Bactericides, Corrosion Inhibitors, Oxygen Scavengers etc that could be in use at different stages (injection points) for treatment of the same formation water.
The flow declined during the duration of the test which also produced formation water
The high chloride ion content in the produced formation water
, in combination with produced solids settling on the bottom of the pipeline in low lying locations, weakened or chemically damaged the protective iron sulphide scales and corrosion inhibitor film.
Hurricane announces that the 205 21a-7Z well (the "Horizontal Sidetrack Well") has achieved a sustainable flow rate using an Electrical Submersible Pump of 14,500 stock tank barrels of oil per day with no produced formation water
The produced formation water
was intended for pressure maintenance in the Red Fork formation, but proved incompatible with shallower formation fluids.
