Development and service of drilling fluid


Universal defoamer of drilling fluids. TU U 24.1-34962841-004: 2008


  • Appearance of the ready-to-use reagent: viscous white or yellow-beige fluid;
  • Water solubility: Insoluble;
  • Mass fraction of dry residue in the reagent: 30-40%;
  • Reagent density: 990-1020 kg / m3;
  • reagent pH: 6-8;


  • Reagent "Pegas" is designed to deal with zavozdushennostyu drilling fluids by reducing the surface tension at the interface phase.
  • Reagent "Pegas" can be used in all types of drilling fluids, water-based. Thus, the defoaming action of the reagent is not dependent on the type of stabilizer and polymer is manifested both in and in the lignosulfonate systems.
  • Reagent works effectively in drilling muds with high rheological parameters thickening which occurred due to the high temperature, exposure to high molecular weight polymeric reagents and contamination of a finely divided slurry of cuttings.
  • Before using the reagent "Pegas", make sure no residue, if necessary, it is recommended to mix the reagent directly into the container for its transportation.
  • To achieve the greatest effect defoaming, agent input into the drilling fluid should be done thin stream, over several cycles of circulation.
  • The drilling fluid treated reagent "Pegas", must also be stirred into the receptacle.
  • Reserve reagent concentration "Pegas" in most cases, not more than 0.2-0.3%. While current treatments required amount of reagent - 0.05-0.1%. Reagent "Pegas" has a faint, a side effect of thinning and temperature stabilizers.


  • Effective antifoam reduces solution viscosity increases their thermal stability.
  • Unlike conventional defoamers such as AM-5, MAC 200 is ready to use without additional dissolving in the diesel fuel.
  • Compatible with all types of reagents, including high molecular weight polymers such as polyanionic cellulose, AbramiX®, Lignopol, BIOCAR-compound.


  • When a substantial amount of gas (which is possible in the case of gas shows) the effect of the use of reagent "Pegas" may be insufficient, necessitating the use of additional mechanical and vacuum degassing methods for flushing liquid. The combined use of these methods significantly improves the efficiency of froth.
  • During long-term storage of reagent (2-3 months) possible separation reagent. Mixing reactant necessary in the container for transportation. The precipitate was easily agitated and properties of the reagent is completely restored.


Reagent "Pegas" is available to customers in liquid form. Delivery of drilling carried out on plastic or metal barrels, volume 50 liters. Reagent on the drill should be stored in a dry ventilated area.
