Lignite Thinner | Dispersant | Deflocculant

GDFCL manufactures the complete range of  Speciallly Modified High Humic Acid  Lignite Thinners, Lignite Dispersants and Lignite Deflocculants for Usage in Water based Mud System, Oil based Mud System and synthetic based mud system.

Lignite Dispersants and Defloculants manufactured by GDFCL  are a specially formulated highly oxidized high humic acid Leonardite which are  chemically modified to function as a clay Defloculant and improve the filter Cake Quality and Provide Fluid Loss . It is partially soluble additive that provides thin low permeability filter cakes accompanied with low fluid loss.

Global Drilling Fluids and Chemicals Limited is  the  Single largests  manufacturer of Lignite deflocculants and Dispersant Thinners  globally which are used in Oil and Gas Drilling, Horizontal Directional Drilling and Mining applications.

Our research team at GDFCL continuously strives to develop new Specialised Lignite Based Thinners having various advantages–

  • Improves thinning and filtration control 
  • Reduces viscosity and gel strengths 
  • Controls rheology, reduces fluid loss, emulsifies oil 
  • Maintains constant pH
  • Reduces HTHP  fluid loss
  • Improves filter cake by reducing its permeability
  • Functions effectively in a wide range of muds even in the presence of contaminants.
  • Can Be used at High temperatures (400 Degree F or 205 Degree C )

GDFCL range of high performance Lignite Dispersants include Finely Ground Oxidized Leonardite, Cauticized lignite,chrome lignite, potassium lignite , Causticized Potassium Lignite  for water Base Mud Systems and a range of High performance Organophilic Lignite for Oil Base Mud Systems  and Polymerized Lignites  which can be customized and manufactured according to various customer needs such as varying temperature, oil well requirements and specifications.

Our Lignite  deflocculants of different chemistry for High Solubility and Enhanced Fluid Loss and to Function in High Salinity Enviornments  and are environmentally friendly and Non Toxic and Function in the presence of Contaminants, in high temperature applications and in a wide range of pH. 

GDFCL range of Drilling Lignite Dispersants are manufactured at our ISO 9001 certified manufacturing facility in Gujarat, where we are equipped with state of theart R&D lab, personnel and research team that continuously strive to improve our full range of lignite Deflocculants.
