Challenges associated with drilling operations are numerous and their adverse effect could
lead to severe damage or even shutting down of the drilling operations. Wellbore instability …

The research objective of this investigation is to explore the influence of filtrate reducer and
reservoir characteristics on the filtration reduction of drilling fluid during the drilling process …

Oil and gas have been facing various difficulties in well drilling due to shale hydration and
swelling when in physical contact with water. Oil-based muds (OBMs) and synthetic based …

Water-based drilling fluids (WBDFs), a more environment-friendly candidate than oil-based
are widely used for drilling oil and gas wells. However, wellbore instability due to active clay …

Chelating agents show very effective performance in different applications in the upstream
oil and gas industry. This study presents a critical review of the application of chelating …

In order to enhance shale stability during drilling operations, efficient shale stabilizers in
water-based drilling fluids become an urgent demand. In this work, a novel shale stabilizer …

Weighting agents such as barite, micromax, ilmenite, and hematite are commonly added to
drilling fluids to produce high-density fluids that could be used to drill deep oil and gas wells …

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) …

Formation damage has the potential to impair and weaken reservoir productivity and
injectivity, causing substantial economic losses. Oil and gas wells can be damaged by …
