Water-based muds (WBMs) cause severe formation damage during the drilling operation
when interacting with clay-containing formations. To avoid clay swelling, it is common …

The need to reduce surfactant adsorption on rock surfaces has been a difficult task in
chemical enhanced oil recovery, as it directly impacts the economics of the project. This …

Wellbore instability caused by shale swelling and dispersion has always been a thorny
issue for drilling complex formations. Nanotechnology has offered a revolutionary solution …

The inhibition attributes of drilling formulations typically rely on the type of additives,
concentration, and reactivity with shale formations. In this work, the impact of ZnO and …

The surface properties and applications of mixtures of an anionic surfactant (sodium lauroyl
lactate (SLL)) and cationic surfactant (gemini quaternary ammonium salt with a hydroxyl …

In this study, three different novel cationic surfactants decyl-trimethyl-ammonium bromide
(S1), Octyl-trimethyl-ammonium bromide (S2), hexyl-trimethyl-ammonium bromide (S3) were …

Water-based drilling fluids are widely employed in the oilfield industry for the efficient and
smooth drilling of wellbore reservoirs. In this study, a novel drilling formulation was prepared …

Polymer inhibitors for deep shale gas drilling have poor temperature resistance and can
influence the rheological attributes of the drilling muds. To overcome this issue, a high …

One of the foremost causes of wellbore instability during drilling operations is shale swelling
and hydration induced by the interaction of clay with water-based mud (WBM). Recently, the …

During hydrocarbon drilling operations, the presence of hydrogen sulfide (H2S) gas could
cause serious health and safety issues. Scavenging this gas and eliminating its impact are …
