This work presents a comprehensive review on the use of bio-inhibitors for stabilizing gas/oil
shales during drilling and hydraulic fracturing. The swelling and dispersion inhibiting …

Three different deep eutectic solvents CM-DES, CP-DES and CIM-DES were synthesized
and investigated for their novel use as shale inhibitors. Their inhibitive properties were …

The hydration and swelling of shale cause borehole instability and seriously threaten the
drilling safety, especially for the use of water-based drilling fluids. In this paper, the potential …

It is an urgent subject to search high-performance shale inhibitors used in water-based
drilling fluids for drilling safety. In the present work, two imidazolium-based ionic liquids (ILs) …

Water-based drilling fluids are extensively used for drilling oil and gas wells. However, water-
based muds cause clay swelling, which severely affects the stability of wellbore. Due to two …

The hydration and swelling of shale caused by water in water-based drilling fluids is one of
the most important problems that causes wellbore instability. The development of high …

The seepage coupling effect between the borehole rock mass and borehole fluid and the
effective stress field distribution around the wellbore are obviously different under different …

A series of sulfonated lignin (SL) samples modified with a silane coupling agent (Si–SL) was
investigated as a biodegradable shale inhibitor for water-based drilling fluid (WBDF). Cutting …

Borehole instability problem is one of the key problems in drilling engineering, especially the
shale formation with bedding planes and natural fractures, the failure of shale rock could be …
