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 …

The frequent occurrence of casing failure has significantly affected the development of shale
gas in the Sichuan Basin. Based on engineering and geology analyses, natural fracture/fault …

This paper proposes a novel way to study the casing structural integrity using two
approaches of finite element analysis (FEA) and machine learning. The approach in this …

Casing deformation frequently occurs in shale gas wells during hydraulic fracturing. While
the failure mechanism of casing ovality deformation is unclear due to the interweaving and …

With the significant increase in multistage hydraulic fracturing in the last two decades,
occurrence of casing failures has also become noticeable, raising wellbore integrity …

One of the challenges of unconventional resource development is the identifying and
preventing casing failures caused by the hydraulic fracturing process. Multiple mechanisms …

Wells are sometimes deformed due to geomechanical shear slip, which occurs on a
localized slip surface, such as a bedding plane, fault, or natural fracture. This can occur in …

Casing deformation during hydraulic fracturing is a serious problem in Weirong shale gas
field. This study investigated the casing deformation mechanism and the influence of …

Casing deformation problem caused by hydraulic fracturing treatments has seriously
reduced the number of fracturing stages. A well understanding of the mechanism and …

One of the challenges encountered in hydraulic fracturing of unconventional resources is
casing deformation. Casing deformation statistics vary across different regions of the world …
