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 …

Casing deformations during hydraulic fracturing are a serious problem in the Weirong shale
gas field. This study focuses on the mechanism of shale swelling-induced casing …

Accurate prediction of dynamic thermal behaviors during multi-stage hydraulic fracturing is
profound which can avoid performance deterioration of fracturing fluids or failure of …

Horizontal wells and multi-stage hydraulic fracturing technology make it possible for large-
scale commercial exploitation of shale gas. However, the problem of casing deformation of …

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 …

During marine hydrate production, some potentially undesirable consequences of casing
failure and deformation are prone to occur. However, conventional planar model used in oil …

Shear deformation often occurs during multistage fracturing of shale gas worldwide,
increasing the operation cost of gas well completion and lowering the well's productivity; …
