Thiourea Acid Corrosion Inhibitor
CAS: 62-56-6
Thiourea is an effective corrosion inhibitor used in acidizing operations and acid cleaning of oilfield equipment, protecting steel tubulars from attack by hydrochloric and hydrofluoric acid systems. It adsorbs onto metal surfaces through its sulfur and nitrogen atoms, suppressing both anodic and cathodic corrosion reactions. Thiourea is typically used in combination with other inhibitors and intensifiers for synergistic protection.

Treated Bentonite for Drilling Fluids
CAS: 1302-78-9
Treated bentonite is a sodium montmorillonite clay mineral that serves as the primary viscosifier and filtration control agent in water-based drilling fluid systems. API-grade treated bentonite hydrates readily in freshwater to build yield point and gel strength for cuttings suspension, with a yield of ≥91 bbl/ton. It forms a flexible, low-permeability filter cake on the borehole wall during drilling operations.

Xanthan Gum XCD Polymer for Drilling Fluids
CAS: 11138-66-2
XCD (Xanthan Gum) polymer is a fermentation-derived polysaccharide biopolymer used as a viscosifier and suspension agent in water-based drilling fluids. It provides excellent low-shear-rate viscosity and yield point for efficient drill cuttings suspension and transport, while maintaining low circulating viscosity for good pump efficiency. XCD polymer is salt-tolerant and effective in both fresh water and saturated brine mud systems.

Zinc Phosphate Anticorrosion Pigment
CAS: 7779-90-0
Zinc phosphate is a non-toxic, lead-free anticorrosion pigment used in protective coatings for oilfield equipment, pipelines, offshore structures, and industrial steel. It functions through multiple mechanisms: barrier effect, cathodic protection from zinc ion release, and phosphate passivation layer formation on metal surfaces. At 10–30% pigment loading in epoxy, alkyd, and polyurethane primers, it provides 1500–3000 hours salt spray resistance.
