OBM Additives

UBPro-446 is a high-performance oil soluble zinc-based H2S scavenger for efficient hydrogen sulfide removal in pipelines, storage tanks, crude oil and multiphase oilfield systems.

High-Performance H₂S Scavenger for Oil, Gas & Water Treatment

UBDrill-261 is a high-performance oil-based mud thinner and rheology modifier designed for OBM systems. It reduces viscosity, improves flow properties, and enhances drilling efficiency under high temp

UBDrill-242 is designed to “build structure without over-thickening the system,” ensuring strong low-shear suspension capability while maintaining efficient flow properties under high-shear conditions. This makes it suitable for modern high-performance OBM systems where barite sag control and stable rheology are critical.

Corrosion Inhibitor (Oil soluble) 1641 is oil soluble, tackle the challenges especially in dealing with high H₂S, CO₂ and CL^-,wich cause the sweet or sour corrosion. 

We designed this for batch treatment or downhole wet sour and sweet wells.

On a par with  VERSAMUL  as well as CarboMul.  

UBDrill-214 is comprises of modified amidoamine, oxidized fatty acids and low-toxic organic solvent.

It servesas a primary emulsifier in oil-base mud systems.
