Drilling through reactive shale formations is normally associated with borehole instability
and is a problem the petroleum industry continues to face every day, with enormous losses …

The failure criterion is a very important aspect of the wellbore stability analysis. But the Mohr–
Coulomb criterion, a most commonly used failure criterion, is usually too conservative, due …

Chemical and mechanical coupling are the most important factors affecting wellbore
instability. The main objective of this research is to propose a wellbore stability analysis …

Borehole instabilities pose significant challenges in drilling and completion operations,
specifically in the areas where pre-existing fractures are intersected by the borehole. In-situ …

Traditional water based fluids tend to penetrate into shale formations, and interact with clay
minerals, which results in clay swelling and wellbore instability. The larger content of clay in …

Exploring and develo** oil and gas in deepwater field is an important trend of the oil and
gas industry. Development of deepwater oil and gas fields from a platform always requires a …

Ultra-extended-reach wells can be drilled from one platform to develop the remote
surrounding satellite oil and gas reservoirs in deepwater. Although the platform is in shallow …

During drilling operation, the occurrence of borehole instability is one of the major problems
in which many parameters can affect the wellbore stability. In many cases, wellbore …

Nanofluids have gained significant attention as a promising solution to several challenges in
drilling operations. Nanoparticles, due to their exclusive properties such as high specific …
