Recent advances of modified polyacrylamide in drilling technology

Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based. In Malaysia, a support fluid or a full-length casing is used in the stabilisation of the excavation site, which is then followed by the formation of concrete casting known as a bored pile.

Construction of oil and gas wells at offshore fields often involves high formation pressure and the presence of swellable clay rocks in the section. In addition, productivity preservation is also an important aspect. For this purpose, it is necessary to reduce the solids content of the drilling mud. The purpose of this work is to develop, improve, and study compositions of weighted drilling
