Horizontal wells provide high drainage area within the reservoirs. Advancements in
horizontal drilling technologies are utilized to develop unconventional resources such as …

Overbalanced drilling is the most common drilling technique; nevertheless, it has several
disadvantages such as formation damage, mud losses, and stuck pipes; challenges that are …

Increasing cuttings bed height is a serious concern during extended-reach well drilling. In
order to predict and prevent cuttings bed height increase, it is essential to study how the …

Poor cuttings transport in deviated wells limit drill rate, induce excessive torque and drag, or
in severe cases result in a stuck pipe. This paper presents a generalized data-driven model …

Drill pipe rotation is considered a relevant factor for cuttings transport and hole cleaning.
However, in the term “rotation” is often used as a moniker for the combination of plain drill …

Drillpipe eccentricity is a common issue in horizontal drilling operations. The eccentricity is a
non-manipulative parameter by itself but its impact is a function of various parameters such …

Microhole-drilling technology is a high-efficiency and low-cost technology that has
developed rapidly in recent years. However, during microhole-horizontal-well drilling …

Inclined and horizontal wells are prone to the accumulation of drilling cuttings.
Determination of the optimal drilling parameters that facilitate cuttings removal is a key …

The increasing global energy demand has pushed the oil industry towards developing more
innovative and advanced methods of enhancing oil recovery even under unfavourable …

Effective cuttings transport has long been a challenge in oil and gas horizontal drilling, and
inadequate wellbore cleaning can result in severe drilling accidents including stuck pipe …
