  • Can polyacrylamide be used for drilling?
  • However, polyacrylamide with high molecular weight can be a good candidate at lower concentrations to meet the drilling requirements. The viscosity of polyacrylamide at all concentrations decreases with increasing temperature, according to Magzoub et al. (2021).
  • Can nanomaterials be used as lubricant additives in polymeric based drilling fluid?
  • Ismail et al. (2016) investigated the nanomaterials such as multiwall carbon nanotube, nanosilica, and glass beads as lubricant additives in the polymeric-based drilling fluid that consist of polyanionic cellulose, and partial hydrolytic polyacrylamide.
  • What is lubricant used for in drilling?
  • Lubricant with its limitations The lubricant is used to control the drag, friction and torque in a drilling. Previous study shown the lubricity of drilling fluid has been improved by 25% with the modification of polyacrylamide using zinc oxide, which was studied by Aftab et al. (2016).
  • What is modified polyacrylamide drilling fluid?
  • Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
