MEX-TROL HT

DESCRIPTION

MEX-TROL HT is polymerised lignite designed to control water-loss. This additive is a Polymer Lignite Resin used to reduce fluid loss during the drilling process in high temperature drilling operation conditions. 

MAIN PHYSICAL PROPERTIES

Appearance:                                                                 Dark-brown powder

Density:                                                                        1.5 – 1.7 g/cm3

рН (1% solution):                                                           8.8 – 9.2

Bulk density:                                                                 897 kg/m3

APPLICATION:

MEX-TROL HT is a wide range fluid loss reducer, which can be used to treat the majority of water-based drilling fluid systems. The additive is specially effective to treat fresh water-based heavy muds and gypsum water based muds. Polymer exhibits increased thermal stability of drilling fluids above 200оС. The additional advantage of the additive used to treat heavy-weight drilling fluids is the reduction of water loss parameters without any increase of the rheological properties.  The recommended concentration of the additive varies within 5 to 15 kg/m3 dependent on the required level of fluid loss and on the mud properties. The additive is designed to avoid any effect on the rheological properties of the drilling fluids, but it can insignificantly reduce the viscosity of the bentonite mud. 

      ADVANTAGES:

      LIMITATIONS:

  • It stabilizes drilling fluid loss in a wide range of temperature conditions.
    • It does not increase the mud viscosity.
    • It improves the mud cake quality.
    • It stabilizes rheological properties.
    • It is resistant to drilling fluid contamination.
    • It does not contain chromium.
  • High content of salts reduces the efficiency of the additive, thus requiring the increase of its concentration.
