Product Description:
Product Application:
Product Dose:

The role of CMC-lv in drilling is as follows:

  •  Mud with CMC can make the borehole wall to form filter cake with the features of thin, sturdy and low permeability filter, so that it can reduce water loss.
  • Mud added CMC can let rig get low initial gel strength, and it’s easy to release the gas wrapped inside the mud as well as discard the debris quickly into the morass.
  • As the same with other suspended dispersions, drilling mud has a certain existence period, and CMC added into can make it stable so as to extend the existence period.
  •  Mud contained CMC is rarely influenced by fungus, therefore, there is no need to maintain a high pH values and use preservatives.
  •  When using drilling mud added CMC as treatment agent of flushing fluid, it can anti-various soluble salts pollution.
  • The mud contained with CMC has good stability, it cannot lose water even if the temperature is above 150℃.
Product Note:
  • Widely available and low cost polymer for fluid Loss control.
  • It is an effective at providing filtration control in most water based drilling fluids.
  • It is effective in low concentrations.
  • It is Non–Toxic.
  • It is not subjected to bacterial fermentation and calcium contamination.
  • Can be sed Fluid systems
