RPMinerals supplies a wide range of products used as drilling fluid additives for both water base and oil base drilling fluid systems.

RPMinerals produce API-grade barite under the trade name AMCOBAR


RPMinerals produces API-section 9 bentonite under the trade name RP GEL 9 and produce API Section 11 bentonite under the trade name RP GEL 11.


Are used to increase viscosity for improved hole cleaning, to increase bentonite yield and to clarify or de-water low solids drilling fluids. Flocculants cause colloidal particles in suspension to group into clusters or flocs causing solids to settle out. Flocculants commonly used in the oilfield include:

  • Drill Salt (Brine), NaCl, Sodium Chloride
  • KCL, Potassium Chloride
  • Hydrated Lime, Calcium Hydroxide
  • Gypsum, Calcium Sulphate
  • Soda Ash, Sodium Carbonate
  • Sodium Bicarbonate (Bicarbonate of Soda)
  • TSPP, Tetrasodium Pyrophosphate
  • Polyacrylamide Polymers
  • Drill Salt (Brine), NaCl, Sodium Chloride

Used to increase viscosity for better hole cleaning and suspension of solids.

  • Water based drilling fluids:

    • RP GEL 9 (API Section 9) Bentonite
    • RP GEL 11 (API Section 11) Bentonite
    • CMC, Carboxy Methyl Cellulose
    • BrineGel A (API grade salt water viscosifier)
    • Xanthan Gum
    • Guar Gum
    • PAC HV, Poly Anionic Cellulose (High Viscosity)
  • Oil based drilling fluids:

    RPMinerals manufactures a full range of organophilic clay products including organophilic bentonite under the BENTOIL trade name and organophylic attapulgite under the ATTOIL trade name. These products are used as viscosifiers and gelling agents in oil base drilling fluids to increase carrying capacity and suspension properties, providing cost effective removal of cuttings.

    • BENTOIL 100 Organophilic Bentonite
    • BENTOIL 300 Organophilic Bentonite
    • BENTOIL 300 BD TXP
    • BENTOIL 400 Organophilic Bentonite
    • BENTOIL 500 Organophilic Bentonite
    • BENTOIL 700 Organophilic Bentonite
    • ATTOIL Organophilic Attapulgite
    • SEPOIL Organophilic Sepiolite

The primary function of Loss Circulation Materials is to physically plug the zone in the formation that is losing drilling fluids. Commonly used products offered by RPMinerals include:

  • Nut Plug
  • Mica (Medium grade)
  • Mica (Fine grade)
  • Mica (Coarse grade)
  • Ultraseal

Used to control formation pressures, prevent formation caving and facilitate pulling dry pipe. RPMinerals provides the following Weighting Agents:

  • AMCOBAR Barite
  • Calcium Carbonate
  • Drilling Detergents
  • Stuck Free Pipe Oils
  • EP Lube
  • Biocides
