Drilling fluids must be cautiously designed to form an impermeable filter cake layer that
diminishes the intensity of solid and mud invasion during drilling of a well. Inability to abate …

Fluid loss circulation control during drilling operations is becoming more challenging as
exploration moves from conventional to unconventional energy resources. The process of …

Drilling operations encounter various problems, many of which affect mud quality and may
delay or suspend drilling. Wellbore instability is one of the many problems that drilling …

Red mud is generated from alumina production through bauxite digestion with caustic soda.
Ma'aden aluminum production estimated the abundance in a million tons as 2.65: 1: 2 for …

Barite sag causes pressure fluctuations in the wellbore, which is undesirable. These
problems usually occur with oil-based muds (OBMs; invert emulsion muds) and are …

Sagging has a detrimental outturn on the drilling effectuation and increases the drilling risks.
Drilling deviated wells and wells with high pressures and temperatures has a greater impact …

A common problem in the construction of bored piles is the instability and deformation of the
hole wall. Bentonite mud is usually employed to maintain the stability of the hole wall …

Portland cement (PC) is known for its environmental and technical concerns and massive
energy consumption during manufacturing. Geopolymer cement is a promising technology …

A required feature of any drilling formulation is to mitigate the formation damage by having
an excellent filtration and filter cake properties. The key factor for preventing and limiting …

Barite is often utilized to control the weight of drilling muds. However, in inclined wellbores,
barite particles settle out of the mud in a lateral direction and quickly reach the wellbore wall …
