Shale formations are known for their chemical interactions with water based muds which
may result in swelling, bit balling or even closure of the wellbore. As a result, eco-friendly …

Water-based drilling fluids (WBDFs) are widely used for drilling oil and gas wells. Water-
based drilling fluids are considered economical and environmentally friendly compared to …

The continuous growth of energy requirements, together with diminishing production,
necessitates tireless efforts to develop new technology frontiers in oilfield operations. The …

In this work, a novel low molecular weight zwitterionic copolymer for improving wellbore
stability, which is expected to be an alternative to the current shale inhibitors, was obtained …

Shale hydration and swelling are disadvantageous for well drilling, especially when using
water-based drilling fluids. In this work, the ionic liquid 1-vinyl-3-ethylimidazolium bromide …

A quantitative description is presented of the dynamical process of polymer intercalation into
clay tactoids and the ensuing aggregation of polymer‐entangled tactoids into larger …

The hydration and swelling caused by the contact of shale with water during oil and gas
drilling have caused many difficulties in drilling operations. Water-based drilling fluids …

Based on the adsorption mechanism analysis of polyhydroxy organic compound on a shale
surface, a novel polyhydroxy organic amine shale hydration inhibitor N, N, N′, N′-tetrakis …

Fluid–shale interaction mechanisms and their implications on shale mechanical property
evolutions are essential for both shale gas exploitation and CO2 sequestration. To …

In this study the synergistic behavior that occurs when three different cationic inhibitors for
clay swelling were associated with brines containing NaCl and KCl was evaluated. These …
