Background Ionic liquids have received a lot of interest in recent years from scientists and
academics due to their distinctive qualities, including low vapor pressure, low toxicity, high …

Drilling fluids are the core of drilling operations, and they are responsible for many roles,
such as lubricating drill string, cooling down drilling equipment, maintaining wellbore …

Recently, mucilage extraction from plant sources has been remarkably explored due to its
potential applications. Several underutilized fruits such as Aegle marmelos are the potential …

During high temperature and high pressure well drilling, effective filtration loss control is a
great challenge for a water-based drilling fluid. In this study, environmentally benign carbon …

Designing an effective drilling mud is a critical aspect of the drilling process. A well-designed
drilling mud should not only provide efficient mud hydraulics but also fulfill three important …

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 …

Several wellbore instabilities issues arise when drilling into any reactive shale formation.
These problems affect the drilling activity seriously which eventually results in non …

Shale hydration has been a frequent and challenging technical problem causing wellbore
instability in oil and gas drilling processes. The aim of this study is to design a novel …

In-situ leaching process of weathered crust elution-deposited rare earth ore (WCE-DREO)
often faces problems such as poor permeability and occurrence of landslides. The main …

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 …
