Abstract (en)
[origin: GB2359104A] A method of treating an oil well to inhibit scale formation. An oil soluble scale inhibitor (e.g. a penta-phosphate derivative) in a hydrocarbon phase (e.g. kerosene, lamp oil, diesel or crude oil) is injected into the well during the completion phase. The inhibitor hydrolyses on contact with connate water in the well and the active part enters the water phase. It remains in the water phase while oil is extracted and until the water breaks through. At that stage, the inhibitor becomes active in inhibiting scale formation.
