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 …

A multi-scale numerical investigation for fault slip and casing deformation is carried out by
combining a large-scale distinct element model to simulate the hydraulic fracturing and fault …

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

Titanium alloys are the best candidates to replace steels for drill pipes in horizontal wells.
However, friction welding (FW) may significantly change the properties of titanium alloy drill …

Hydraulic fracturing is repeated in some unconventional wells after production since the
initial fracturing treatment. Due to prior production, the stress field around the existing …

During the multistage fracturing in shale oil and gas wells with tieback and liner, one of the
major challenges is the wellbore temperature variation due to the high-rate fracturing. In …

During marine hydrate production, some potentially undesirable consequences of casing
strength failure are prone to occur. However, conventional methods used in casing …

Low permeability is a key geological factor constraining the development of shale gas, and
reservoir modification to improve its permeability is a prerequisite. Controlled shock wave …

Field evidence of production logs after fracturing have documented the existence of
abundant natural fractures in Weiyuan shale plays, which is widely acknowledged to have a …

In this study, we use the extendedfinite element method (XFEM) with a consideration of
junction enrichment functions to investigate the mechanics of hydraulic fractures related to …
