ZINC OXIDE reacts with H₂S to form an insoluble precipitate of Zinc sulphide that is inert and insoluble in water. ZINC OXIDE is not pH dependent; it is effective at very alkaline pH such as 11.5 – 12.5.

ZINC OXIDE is utilized to remove sulfides resulting from an influx of hydrogen sulphide gas or to pretreat the active drilling fluids when influxes are expected.

As a preventive measure, the drilling fluid should be pre–treated with ZINC OXIDE the normal treatment is 1.0–2.0 lb/bbl (3.0 – 6.0 kg/m³). Subsequent doses will depend on the sulfide detected. (1.0 ppb of Zinc oxide per 600 mg/l of sulfides). Use a garret Gas train with proper dragger tubes to detect the sulphide content.

Transportation of ZINC OXIDE is not restricted any regulatory agency.

Utilize normal precautions for employee protection when handling chemical products. Utilize appropriate respirator, gloves, goggles and apron. Refer to the Material Safety Data Sheet (MSDS) for this product prior to use.

ZINC OXIDE is packaged in 25 kgs multiwall paper sack.
