Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

documented, for it was brought from the Near East to France by M. Cousin6ry in 1817; in 1845 it was acquired for the national collection from the Collection F61ix Lajard into which it had passed. This information is important because it guarantees the genuineness of the seal which measures ht. 27 mm., diam. 11 mm. (Fig. 1)1. The scene represented on it
