As the concept of green and sustainable development gains widespread acceptance, the
demand for non-toxic, biodegradable, renewable, and widely sourced natural materials …

Frequent wellbore instability issues caused by shale hydration and dispersion are
encountered in water-based drilling fluids. In order to mitigate shale hydration, a …

This study evaluated the potential of 1-ethyl-1-methylpyrrolidinium bromide (1E1MPyBr)
ionic liquid as a shale swelling inhibitor for water-based mud. Firstly, a linear shale swelling …

Shale formations adsorb water and swell when they are in contact with water-based drilling
fluids due to the content of active clay minerals. Shale swelling in the well wall is one of the …

Wellbore instability issue is a common occurrence in the development of clean energy
sources such as shale gas. Low-melting mixture solvents (LoMMSs), as a novel and …

Shale hydration is the primary cause of wellbore instability during drilling processes. In this
study, two non-fluorinated silane-coupling agents, octyltriethoxysilane (OTES) and (3 …

Biosurfactants (BSs) are highly biodegradable, environmentally benign, and multifunctional
substances having diverse industrial uses, including environment bioremediation. Because …

Swelling of clay minerals is one of the main factors restricting the efficient exploration and
development of shale oil and gas. To solve this issue, the free radical induction method was …

As oil reserves in shallow wells continue to deplete, the drilling industry must shift its focus
toward extracting oil from deeper and more complex formations. Water‐based drilling fluid …

During the drilling process, the hydration and expansion of shale are one of the main
reasons for wellbore instability, which can lead to stuck drilling and economic losses. A …
