Numerical investigation for different casing deformation reasons in Weiyuan-Changning shale gas field during multistage hydraulic fracturing
TL;DR: In this paper, the authors investigated the impact of the lithologic interface on casing deformation and found that the effect of the interface on the casing stress plays a decisive role under the combined effect of internal and external pressures when the cement sheath is completed.
Journal ArticleDOI
Casing structural integrity and failure modes in a range of well types: a review.
TL;DR: In this article, a taxonomy of the major causes and cases of casing failure in different well types is covered, and an overview of casing trend utilisation and failure mix by grades is provided.
Journal ArticleDOI
Casing deformation from fracture slip in hydraulic fracturing
TL;DR: In this article, the failure mechanisms of casings in shale gas wells are revealed based on theoretical analysis, numerical simulation and field measurement, and the countermeasures are recommended through parametric sensitivity analysis.
Journal ArticleDOI
Numerical simulation of casing deformation during volume fracturing of horizontal shale gas wells
TL;DR: In this article, three-dimensional physical and finite element models were established using a stage finite element model procedure to investigate the influences of fault slippage on casing stress and displacement.

Fault reactivation and induced seismicity during multistage hydraulic fracturing: Microseismic analysis and geomechanical modeling
TL;DR: In this paper, a case study of fault reactivation and induced seismicity during multistage hydraulic fracturing in Sichuan Basin, China is presented, where the authors show that lower injection rate and lower fluid viscosity would be helpful in reducing casing deformation but not in mitigating seismicity.

Nonplanar Fracture Propagation From a Horizontal Wellbore: Experimental Study
TL;DR: In this paper, experimental results related to hydraulic fracturing of a horizontal well, specifically the nonplanar fracture geometries resulting from fracture initiation and propagation, are presented and recommendations to ensure clear communication channels between the wellbore and the fracture are given.

Performance of horizontal wells with fracture networks in shale gas formation
TL;DR: In this paper, a semi-analytical model was proposed by discretizing all these fractures into small segments with consideration of fracture interferences, SG diffusion, SG adsorption, and effect of stress-sensitivity of permeability.
