Shale stabilization is very significant in avoiding any wellbore instability issues during
drilling. Water based drilling mud is usually used with mechanical or chemical inhibitors to …

The objective of this paper is to provide a review of casing deformations that are related to
the placement of Multi-Stage Hydraulic Fracturing (MSHF) in unconventional plays. This …

An essential feature of shale is swelling induced by shale–liquid interactions. Shale swelling
is an important inducing factor for shale damage that affects shale mechanics. A better …

Shale-liquid interactions can lead to shale swelling, shale damage and affect the
mechanical and other properties of shale. The relationship between shale swelling and …

Casing deformation is often encountered due to hydraulic fracturing in the unconventional
reservoir. Analysis of 3D seismic, microseismic and logging data shows that the casing …

In the process of hydraulic fracturing of shale gas horizontal wells in the Weiyuan area of
Sichuan, China, casing deformation (CD) is a frequent problem that has seriously affected …

Casing shear deformation caused by fault slip is a serious problem that restricts shale gas
development. As yet, there is no effective method for controlling casing shear deformation. In …

Casing deformation caused by fault and fracture sliding derived from fracturing has attracted
growing attention. Casing deformation frequently occurs during the hydraulic fracturing …

The casing deformation prevention technology based on the optimization of cement slurry is
proposed to reduce the casing deformation of shale oil and gas wells during hydraulic …

The densified-multi-cluster fracturing, a technology being used to enhance shale gas
production, also shows a special advantage on casing deformation relieved in WeiRong oil …
