MEX-200

DESCRIPTION

MEX-200  is an organic inhibitor for clay and shale. It is efficient to suppress hydration and shale / clay swelling; it prevents further dispersion of shaly cuttings, and it helps to reduce bit-balling and plugging.

MAIN PHYSICAL PROPERTIES

Appearance                                             transparent liquid

Solubility in water                                      100%

Flash point                                              >95°С
рН                                                       6.5 – 7.5

SG                                                       1.22 @ 20°С

PRODUCT USE:

This additive reacts based on the cation exchange and adsorption processes. MEX-200 molecules join active zones located at the edges of clay/ shale particles and they efficiently suppress hydration process, and prevent interaction between clay/ shale particles. MEX-200 may be used for all types of water-based mud systems. This additive may be added to the solution directly to the tank. or through the hopper. It does not require any additional equipment or special measures to treat mud. MEX-200 inhibits non-dispersed clay particles only, so it is recommended to add this additive in the mud system before drilling shale/ clay intervals. The recommended concentration of MEX-200 in the solution shall not exceed 11 to 23 kg/m3.

Together with clay and shale inhibition, MEX-200 help improving the stability of borehole walls, to reduce bit balling and plugging, and to improve the performance of the mud cleaning equipment.

      ADVANTAGES:

      LIMITATIONS:

  • Highly efficient additive.
  • It is easy to mix and to handle.
  • Stable at temperatures up to  150 150°С
  • It does not affect rheological and filtration properties of mud.
  • Environmentally safe and friendly.

 

  • MEX-200 suppresses hydration of any shale/ clay; bentonite, if planned to add into the mud system, shall be pre-hydrated in water.
  • A short-term flocculation may be observed when adding the agent into the mud with high content of fine and active solids.

 

PACKAGING AND HANDLING
