Drilling Fluid Chemicals for Oilfield Drilling

GN New Chem supplies drilling fluid chemicals and mud additives for water-based, oil-based, and synthetic-based drilling systems. The portfolio supports rheology control, filtration control, shale inhibition, lubrication, lost-circulation control, corrosion and scale control, harmful-gas scavenging, and stuck-pipe treatment in demanding drilling environments.

Our portfolio is designed for water-based and oil-based mud formulation, rheology control, filtration control, shale inhibition, lubrication, lost-circulation treatment, contamination control and stuck-pipe response. Rather than treating chemicals as isolated commodities, GN New Chem focuses on the complete operating objective: stable separation, predictable treatment performance, reduced process interruptions, manageable sludge or waste output, and practical chemical consumption.

Application-Focused Chemical Solutions

Treatment programs are selected according to the feed composition, process equipment, operating temperature, water chemistry, contamination profile and required outlet quality. The category serves drilling contractors, mud service companies, oilfield operators, HDD contractors, drilling-fluid formulators and regional distributors. Products can be supplied as individual additives or as part of an integrated chemical program supported by laboratory screening, compatibility checks and field optimization.

Products in This Category

• Viscosifiers and Rheology Modifiers: Viscosifiers and rheology modifiers build and control drilling-fluid viscosity, gel strength, suspension capacity, and hole-cleaning performance. Products can be selected for freshwater, saltwater, brine, high-temperature, water-based, and nonaqueous systems.
• Fluid Loss Control Additives: Fluid loss control additives reduce filtrate invasion and help form a thin, low-permeability filter cake. They support wellbore stability and formation protection across water-based, oil-based, brine, and high-temperature drilling-fluid systems.
• Shale Inhibitors and Clay Stabilizers: Shale inhibitors and clay stabilizers reduce clay hydration, swelling, dispersion, and cuttings degradation. They improve wellbore stability, maintain cleaner drilling fluids, and reduce dilution and waste volumes in reactive formations.
• Drilling Fluid Lubricants: Drilling fluid lubricants reduce torque, drag, friction, differential-sticking risk, and wear in water-based and nonaqueous drilling systems. Selected products can also improve rate of penetration and support extended-reach and horizontal drilling.
• Lost Circulation Materials: Lost circulation materials seal pores, fractures, and highly permeable formations to reduce drilling-fluid losses. Blended solutions can be designed for seepage, partial, severe, or total losses and preventive wellbore-strengthening treatments.
• Drilling Fluid Defoamers: Drilling fluid defoamers control entrained air and surface foam in water-based muds, brines, and chemical-mixing systems. Effective foam control supports accurate density measurement, stable pumping, improved solids control, and reduced tank overflow.
• Dispersants and Thinners: Dispersants, thinners, and deflocculants reduce excessive viscosity and gel strength caused by reactive solids, contamination, or high temperature. They help maintain pumpability, solids-control efficiency, and stable rheology.
• Emulsifiers and Wetting Agents: Primary and secondary emulsifiers stabilize invert-emulsion drilling fluids, while wetting agents maintain oil-wet solids and weighting materials. These additives help control electrical stability, rheology, filtration, and contamination tolerance.
• Weighting Agents: Weighting agents increase drilling-fluid density to control formation pressure and maintain well stability. Product selection considers required density, particle-size distribution, sag tendency, abrasiveness, acid solubility, and formation-damage risk.
• Drilling Fluid Biocides: Drilling fluid biocides control sulfate-reducing bacteria, acid-producing bacteria, and slime-forming organisms in water-based drilling fluids, completion fluids, makeup water, and circulating systems. Treatment helps prevent fluid spoilage, odor, rheology loss, polymer degradation, and microbiologically influenced corrosion.
• Scavengers: Drilling fluid scavengers reduce harmful components such as hydrogen sulfide and dissolved oxygen in drilling and completion fluids. H₂S scavengers reduce personnel exposure, corrosion, and fluid-performance risks, while oxygen scavengers protect drillstring, piping, and circulating equipment in makeup water and brines.
• Corrosion and Scale Inhibitors: Corrosion inhibitors reduce attack on drillstring, casing, piping, and surface circulation equipment exposed to drilling fluids, completion fluids, sour gases, and brines. Scale inhibitors control carbonate and sulfate deposits caused by high-salinity fluid mixing and changes in temperature or pressure.
• Pipe-Freeing Agents: Pipe-freeing agents treat differential sticking, filter-cake adhesion, and selected mechanical restrictions by wetting, penetrating, dispersing filter cake, and reducing friction between the drillstring and wellbore. Water-based, oil-based, or non-hydrocarbon spotting fluids should be selected according to mud system, sticking mechanism, bottomhole temperature, and formation conditions.
