Landoil Chemical Group Co., Ltd

Landoil is a professional manufacturer of Polyanionic Cellulose (PAC and Carboxymethyl  Cellulose (CMC), widely used in drilling fluid and drilling mud.Our products passed the API 13A and ISO cetification. 



  • PAC R
    PAC-R is a high molecular weight purified polyanionic cellulose polymer that is an extremely effective filtration control additive, viscosity and clay encapsulator in fresh, hard and saline water....

  • Application

    Landoil PAC R is multifunction, an excellent viscosifier promoting better hole cleaning, forms a protective colloid which inhibits the hydration of water sensitive formations and promotes borehole stability through filtration control. Landoil PAC HV will enhance the lubricating properties of the fluid and can be added to foam to improve cuttings transportation. Landoil PAC HV can be added to enhance a Bentonite-based fluid system and is compatible with most polymers lubricants. Addition rates can be adjusted to suit specific applications.



    2.effective in low concentrations

    3.rapid increase in viscosity

    4.reduce water loss

    5.improves shale control

    6.natural polymer-based product, the environmental impacts is minimal

    7.extends life of foam or stiff foam in air drilling

    8.with a higher D.S, PAC R has a better property of high temperature and salt resistance

    9.Above the API 13A standard.

  • PAC LV
    Landoil PAC-LV is a polyanionic cellulose polymer, which is an extremely effective filtrate reducer in fresh or salty water. It also acts as a thinner in salty water in low concentrations....

  • Landoil PAC LV can be used in any type of water based drilling fluid, including saturated salt water fluids. It will effectively reduce filtrate loss without increasing viscosity. Landoil PAC LV is an excellent shale encapsulater and inhibitor in medium to high concentration.


    1.Landoil PAC-LV is effective in all types of water based muds, including salt saturated.

    2.effective in the reduction of filtrate in small concentrations.

    3.effective in the reduction of shale dispersion as medium to high concentrations.

    4.effective at moderate to high PH.

    5.non toxic and will not ferment.

    6.with a higher D.S, Landoil PAC LV has a better property of high temperature and salt resistance.

    7.According API 13A standard(A.V.: max 40 cps, Filtrate volume: max 16ml).
