MEX-PAC QL

DESCRIPTION

MEX-PAC QL is high quality polyanionic cellulose that provides outstanding fluid loss control properties. The proprietary technology for grinding and packing (it is supplied in granules) offers services generally exceeding the efficiency of the existing products. The additive is easy to dissolve in cold water, and it provides excellent water loss parameters.

 

MAIN PHYSICAL PROPERTIES

Appearance:                                                                   white granulated powder

Density:                                                                         1.5 g/cm3

рН (1% solution):                                                              6-8       

 

APPLICATION:

MEX-PAC QL is used to reduce water loss in fresh-water-based, salt-water-based and mineralized mud systems. It forms a thin, dense and at the same time elastic filter cake, thus reducing the penetration of the filtrate into the formation, preventing solids sedimentation, and reducing the probability of differential sticking. 

MEX-PAC QL is low viscosity polyanionic cellulose, and it does not affect plastic viscosity of mud.

The recommended concentration of the additive varies within 1 to 8,5 kg/m3 dependent on the required level of fluid loss and on the mud composition.

 

      ADVANTAGES:

      LIMITATIONS:

  • Efficient and effective.
    • It does not increase the mud viscosity.
    • It is resistant to contamination.
    • Effective in a wide range pH values.
    • Resistant to bacterial degradation
    • May be used with all types of water-based mud systems.
  • The efficiency of the additive reduces at the BH temperatures above 150 оС
    • The efficiency is also reduced if the solution hardness >1000 mg/l.
 

 

PACKAGING AND HANDLING 

MEX-PAC QL is packaged in 25 kg multilayer paper bags. Use conventional PPE when handling the product (safety goggles, gloves and dust mask. Handle as recommended in the MSDS.
