  • How can alumina/polyacrylamide nanocomposite improve the viscosity of drilling fluid?
  • Alizadeh et al. (2015) improved the polyacrylamide by synthesising alumina/polyacrylamide nanocomposite through solution polymerisation. As a result, the viscosity of the drilling fluid was more than 300 cP for freshwater mud at 4 wt% and about 100 cP for saltwater mud at 2 wt%, respectively.
  • Is cationic polyacrylamide a good fluid additive?
  • It is recommended to use anionic polyacrylamide because of its minimal interaction and also compatibility with other fluid additives. Due to the cationic polyacrylamides interacting strongly with shale, it can potentially cause formation damage. Both the rheological studies and the zeta potential tests gave the same results.
  • 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.
  • Does shale affect viscosity of polyacrylamide?
  • Usually the sample with highest viscosity is considered to have strong interaction of the bulk fluid with the shale particles, but in this case, the viscosity decreases after adding the shale to the polyacrylamide, i.e., polyacrylamides without shale have higher viscosity values at a given polyacrylamide concentration.
