Oil Based

Additives for oil-based drilling mud

Oil-based mud is an invert emulsion, with brine droplets held inside a continuous oil or synthetic phase. Galaxy Drilling Fluids Pvt Ltd supplies 30 additives for it in its Oil Based division, from emulsifiers and wetting agents to clean-up chemistry.

What the range covers

Emulsifiers and wetting agents hold the system together. Viscosifier grades, fluid loss additives and thinners then adjust its properties, and spotting fluids, lubricants, treated LCM and clean-up chemistry deal with what happens downhole and at the end of the section. The Polvo Series supplies several of these in powder form.

Product designations and classifications are those of the manufacturer. Descriptions explain the function of the chemistry and are not performance specifications. Technical data sheets and certificates of analysis are issued with quotation. Galaxy Drilling Fluids Pvt Ltd is a supplier of these products.

Emulsifiers 8

  • GS Mul P

    Primary emulsifier

    Primary emulsifier. Holds the water droplets inside the oil so the mud stays one stable fluid.

  • GS Mul PAM

    Primary emulsifier, winterized

    The same, formulated to stay pourable in cold weather.

  • Gel Mul S

    Secondary emulsifier

    Secondary emulsifier. Backs up the primary and helps keep solids oil-coated.

  • Gel Mul SAM

    Secondary emulsifier, winterized

    Cold-weather grade of the secondary emulsifier.

  • GS Mul Pro

    Premium secondary emulsifier

    Premium secondary emulsifier. More tolerant of solids and contamination.

  • GS Mul HP

    High-performance emulsifier

    High-performance emulsifier for very salty internal brine. Works as primary or secondary.

  • GS Mul Ai1 / Ai1 HT

    Single-component OBM emulsifier

    One product instead of a package – simpler stock and mixing. HT grade for hot wells.

  • Puro Mul

    Pure invert emulsifier

    Concentrated emulsifier for clean, low-additive invert systems.

Wetting Agents 3

  • Gel Wet / GS Wet HP

    Wetting agent

    Keeps barite and drilled solids oil-coated so they do not water-wet and settle out.

  • GS Sup Wet

    Oil mud conditioner

    Restores the emulsion after water or solids contamination.

  • Puro Wet

    Pure wetting agent for invert emulsion

    Concentrated oil-wetting agent for invert systems.

Viscosifier 3

  • GS Vis SF

    Viscosifier for flat rheology and clay-free mud

    Liquid viscosifier for clay-free non-aqueous mud, giving flat rheology – thickness stays even as temperature and pressure change.

  • GS Vis-FLT

    OBM / SOBM viscosifier

    Main thickener for oil- and synthetic-based mud.

  • GS Vis IS

    Barite suspender (HRP equivalent)

    Keeps barite suspended so it does not settle out of the mud.

Fluid Loss Control 3

  • GS Trol L

    High-temperature liquid fluid-loss controller

    Liquid high-temperature fluid-loss control – no black powder to handle at the rig.

  • GS Trol PD 700

    Polymeric HPHT fluid-loss control application

    Polymer fluid-loss control for high-pressure, high-temperature wells.

  • GS Trol / GS Trol HT

    Natural asphalt

    Natural asphalt. Controls fluid loss and steadies shale. HT grade for hot holes.

Dispersants 1

  • GS Trol AL

    Aminated lignite

    Amine-treated lignite. Fluid-loss control that also supports the emulsion.

Thinners 1

  • GS Thin O

    Thinner

    Thins invert mud that has become too thick from contamination or over-treatment.

LCM 1

  • GS LC Seal TIraq priority

    Treated LCM fibres

    Fibres treated so they seal losses without upsetting the oil-mud emulsion.

Spotting Fluids 1

  • GS Free OBM NW / W

    Spotting fluid for oil-based mud

    Soaking pill to free stuck pipe in oil-based mud. Weighted and unweighted grades.

Lubricants 1

  • GS Lube OBM

    Lubricant for oil-based mud

    Extra lubricity for high-torque directional sections in oil-based mud.

Well Bore Clean Up 4

  • GS Sol

    Solvent, OBM clean up

    Solvent that lifts the oil-mud film off the casing before completion.

  • GS Surf

    Surfactant, OBM clean up

    Surfactant that makes the casing water-wet during displacement to brine.

  • GS Clean ENV

    Asphaltene / paraffin / sludge dissolver

    Dissolves asphaltene, paraffin and sludge deposits.

  • GS Wax Solv / Wax Solv-1

    Wax dissolver

    Dissolves wax and paraffin in production and workover wells.

Specialities 4

  • GS Clay DP

    Organoclay, dry processed

    Dry-processed organoclay – the conventional thickener and suspension agent.

  • GS Micro-Clean

    Micro emulsion for OBM

    Micro-emulsion cleaner – high cleaning efficiency with less spacer volume.

  • GS Mod

    Rheology modifier

    Fine-tunes low-shear thickness and gel strength.

  • GS Thermo Chem

    Thermal chemical well remediation system

    Generates heat downhole to clear damage and deposits around the wellbore.

Frequently asked questions

What are the main additives in oil-based drilling mud?

The core of an invert emulsion is its primary and secondary emulsifiers and a wetting agent, with a viscosifier and a fluid loss additive adjusting its properties. Galaxy Drilling Fluids Pvt Ltd supplies 30 additives for oil- and synthetic-based mud.

Are these additives suitable for synthetic-based mud?

The Oil Based division covers oil- and synthetic-based invert emulsions; GS Vis-FLT, for example, is an OBM and SOBM viscosifier. Suitability of a grade for a given base fluid should be confirmed against its technical data sheet, which Galaxy Drilling Fluids Pvt Ltd issues with quotation.
