Water-based lubricants (WBLs) have been at the forefront of recent research, due to the
abundant availability of water at a low cost. However, in metallic tribo-systems, WBLs often …

Abstract The oil Exploration & Production (E&P) industry provides an important energy
source for the world. However, there is a worldwide concern about the environmental …

The problem of high friction and high torque is one of the most troublesome problems for
engineers in extended reach wells and long horizontal wells. Generally, the friction …

The development of sustainable, cost-efficient, and high-performance nanofluids is one of
the current research topics within drilling applications. The inclusion of tailorable …

An important aspect of hydrocarbon drilling is the usage of drilling fluids, which remove drill
cuttings and stabilize the wellbore to provide better filtration. To stabilize these properties …

The hydration and swelling caused by the contact of shale with water during oil and gas
drilling have caused many difficulties in drilling operations. Water-based drilling fluids …

The traditional drilling fluid lubricants are seriously polluted and have biologically lethal
toxicity to the ecological environment. They cannot be used for a long time in the drilling site …

In the practice of drilling horizontal, directional, and unstable well profiles, the friction
produced by bit balling, wellbore instability, cavings, and dog-legs resulted in excessive …

Deeper drilling depths and high pressure high temperature (HPHT) wells require good well
planning at minimum cost and unproductive time. Polymer nanocomposite has emerged as …

This work investigates the morphologies of Fe 3 O 4 nanoparticles how to affect the
tribological properties when they are applied as nano-lubricating additives. Fe 3 O 4 …
