  • 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.
  • What is polyacrylamide used for?
  • Hence, it is an earth-stabilising fluid that is designed for a variety of applications in the geo-construction industry such as tieback anchors, diaphragm walls, horizontal drilling, tunnelling, slurry trenching, drilled shafts/bored piles, and others. 6.1. Polyacrylamide in drilling technology
  • Can an anionic polymer withstand drilling fluid?
  • The fluid loss test on this drilling system found that anionic polymer can resist about 4.5 × 105 ppm of Cl −, 4 × 105 ppm of Ca 2+, and 1.5 × 104 ppm of Mg 2+ at low pH by adding the acidic gas together at 180 °C. Thus, it can withstand the temperature of drilling fluid up to 180 °C.
  • Does barite/polyacrylamide nanocomposite affect water-based drilling fluid?
  • Roodbari and Sabbaghi (2021) studied the effect of barite/polyacrylamide nanocomposite in the water-based drilling fluid, which showed the incline of its fluid viscosity and the reduction of fluid loss and filter cake thickness. Besides, Kuma et al. (2020) optimised the polyacrylamide-based drilling fluid with the inclusion of hematite.
