Hydraulic fractures represent a particular class of tensile fractures that propagate in solid
media under pre-existing compressive stresses as a result of internal pressurization by an …

Multi-stage fracturing is the current preferred method of completion of horizontal wells in
unconventional hydrocarbon reservoirs. Its core component consists in simultaneously …

Crack problems in multilayered elastic media have attracted extensive attention for years
due to their wide applications in both a theoretical analysis and practical industry. The …

Recent arguments about the possibility of well leakage and underground water pollution in
particular regions have raised significant concerns regarding wellbore integrity during …

Hydraulic fractures that grow at shallow depth or, more generally, near a free surface, curve
towards the surface to become saucer-shaped. These saucer-shaped hydraulic fractures …

We investigate the propagation and arrest of a radial hydraulic fracture upon the end of the
injection. Depending on the regime of propagation at the time of shut-in of the injection …

We investigate the growth of a hydraulic fracture assuming a power-law dependence of
material toughness with fracture length for plane strain and radial geometries. Such a …

The use of particulate lost circulation material (LCM) in drilling fluid is a common method for
mitigating lost circulation from near-wellbore fractures that develop during subterranean …

Poststimulation operations on multistage hydraulically stimulated horizontal wells producing
from conventional and unconventional reservoirs have a major impact on long-term well …

We describe the development of a fluid-coupled 2D extended finite element method (XFEM)
algorithm to model the propagation of nonplanar radially-symmetric hydraulic fractures. The …
