SOBM / Oil-Based Mud Chemicals

Primary (PZT-EMU-P) and secondary (PZT-EMU-S) emulsifiers for SOBM/OBM systems. Achieves Electrical Stability (ES) >800V at HPHT conditions exceeding 300°F (149°C). Flash point >93°C. SG 0.90–0.95 g/mL. Field data shows ≤0.5 ppg reduction in required mud weight vs. conventional emulsifier systems in equivalent density windows.

Oil-wetting agent for solids and drill cuttings in SOBM/OBM systems. Prevents water-wet solids from destabilizing mud rheology. High salinity tolerance - effective up to 250,000 ppm TDS. Stable up to 90°C (194°F).

A drying oil rich in polyunsaturated fatty acids, pressed from flaxseed; boiled/blown (oxidized) grades are chemically modified for industrial use. Used in OBM/SBM systems as an eco-friendlier base-oil component or additive, contributing viscoelastic, film-forming, and lubricating properties.

Bentonite chemically treated with a quaternary amine to render it oil-wet, functioning as the primary viscosifier in OBM/SBM: the direct equivalent of raw bentonite's role in WBM.

A natural or processed asphaltite material providing fluid-loss/filtration control in OBM and HTHP systems, with a secondary shale-stabilization benefit.

Provides an alkalinity reserve in OBM, buffering against acid-gas (CO2/H2S) influx and activating certain emulsifier chemistries: a functionally different role than pH control in WBM.

A specialty additive that fine-tunes the gel-strength/viscosity profile of OBM independently of the organoclay/emulsifier package, often used for HTHP rheology control.

Used to formulate the internal (dispersed) brine phase of invert-emulsion OBM/SBM systems, balancing water activity against the formation to prevent osmotic water transfer and shale destabilization: essential, non-substitutable invert-emulsion chemistry.

An antifoam chemistry formulated specifically for compatibility with oil-continuous systems, since a WBM-grade silicone defoamer may not disperse correctly in an oil-continuous phase.

Chemically modified, amine-treated (organophilic) lignite used as an HTHP filtration control agent in oil-based and synthetic-based drilling fluids. Oil-dispersible, unlike untreated lignite.

Multifunctional conditioning additive for oil-based and synthetic-based drilling fluids, used to improve emulsion stability, solids wetting, and overall fluid condition.
