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 hydrophobically modified polyacrylamide gel be used in high temperature drilling?

Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling J. Mol. Liq., 325 ( 2021), p. 115155, 10.1016/j.molliq.2020.115155 Rheological properties of bentonite-free water-based drilling fluids with novel polymer viscosifier J. Petrol. Sci.

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.

How stable is silica in polyacrylamide based drilling fluid?

Kumar et al. (2020) studied the stability of silica in polyacrylamide-based drilling fluid with the saline environment. The result revealed a maximum pH value of 8 with 2 wt% of sodium dodecyl sulphate (SDS) in that drilling fluid maintained loading up to 3 wt% NaCl.

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.

What is the thermal conductivity of polyacrylamide based drilling fluid?

It showed thermal conductivity around 0.9 Wm −1 K −1 that have 84% improvement when compared to the bare polyacrylamide. Study of filtration and rheological properties in polyacrylamide-based drilling fluid using graphene oxide
