Granular Activated Carbon (Gac) Fact Sheet

  • Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
  • Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
  • What is standard viscosifying agent (PAC R) in water-based mud?
  • Standard viscosifying agent (PAC R) was also used to formulate water-based mud for proper comparison. The properties of the formulated mud systems were analyzed using API standard. A total of four water-based mud systems were formulated for the QAQC analysis and the rheological properties analysis.
  • How effective is PAMC flocculation in turbid water clarification?
  • Chemical and morphology structures of PAMC were characterized and analyzed. Flocculation performance and kinetics were investigated in highly turbid water clarification. Most effective flocculation occurred at pH 4 with the flocculant which contained the highest cationic content.
  • Why is polymer a promising viscosifier in water-based drilling fluid?
  • To date, the polymer becomes a promising viscosifier in water-based drilling fluid because polymer has a better performance as a rheological modifier, shale inhibitor, and fluid loss enhancer ( Ahmad et al., 2018; Belayneh and Aadnøy, 2016; Saboori et al., 2019 ).
