MEX-GUM S

DESCRIPTION

MEX-GUM S is biopolymer and high-purity xanthan gum. It is used to control mud viscosity and structure for the majority of water-based mud systems. This additive improves suspending and carrying capacities of the mud systems, even if added in small concentrations.

MAIN PHYSICAL PROPERTIES

Appearance:                                                                   fine off-white powder

Density:                                                                         1.5 g/cm3

рН (1% solution):                                                              6 - 8

PRODUCT USE:

MEX-GUM S is used to control rheological properties (plastic viscosity, yield point) and structural parameters (gel strength) of the majority of water based mud systems. This additive may be used to treat and control completion fluids.

 The main characteristic of the additive is represented by its ability to create special rheological profiles with the high viscosity parameters at low share rates and low viscosity parameters at high shear rates. This feature provides drilling fluids with high carrying and suspending capacities at minimum drilling pressures. Low viscosity parameters at high shear rates allow to reduce pressure drops in drill strings and to provide max hydraulic capacity of the bit performance. 

 It is recommended to add the agent through the hydraulic hopper as slow as possible to provide its maximum efficiency. It should be 7 to 10 minutes per bag. The additive dissolution rate depends on the temperature of the mix water and on the composition of the solution.

 The recommended concentration of the additive varies within 0.5 to 5 kg/m3 dependent on the required level of viscosity and on the mud composition.

 For maximum efficiency of the additive it is recommended to treat make-up water and to reduce calcium (hardness) below 400 mg/l.

      ADVANTAGES:

      LIMITATIONS:

  • High solubility.
    • Minimal concentrations.
    • Unique rheological profile.
    • Compatible with the majority of drilling mud systems.
  • High content of polyvalent cations.
    • The efficiency is reduced in high high alkalinity and high hardness conditions.
    • The additive is biodegradable (it is recommended to use bactericide with this additive).
    • If the temperature is above 120 оС, it is necessary to use it with a thermal stabilising agent.
