Wellbore instability in oil and gas industry well drillings is a significant challenge that is
linked to shale swelling when shale interacts with free water molecules in the water-based …

Wellbore instability is one of the most serious problems that can occur during drilling, mainly
during drilling oil or gas wells through rocks that contain a higher proportion of clay, such as …

Interest in using nanomaterials to improve shale stability during drilling operations has been
increasing. Herein, a polymer microsphere emulsion (PME) as a high-performance shale …

Wellbore stability in the presence of water-based mud (WBM) is a key challenge for the oil
and gas industry. The present work reports the development of a cost-effective, efficient, and …

Fluid seepage into rock pores not only generates poroelastic stress but also exerts seepage
force on the rock skeleton. However, since the mechanism of the effect of seepage force on …

Fluid flowing through reservoir pores not only generates poroelastic stress but also exerts
seepage force on rock skeleton. However, the mechanism of seepage force is not clear …

In order to effectively solve shale instability problems in the drilling process, the remarkable
capillary effect of shale formations cannot be ignored. In this paper, we report the …
