Lost circulation is one of the most common and costly problems in drilling operations, but in
many operational situations, wellbore strengthening is an effective and economic technique …

Fracture-initiation pressure (FIP) and fracture-propagation pressure (FPP) are both important
considerations for preventing and mitigating lost circulation. For significant fluid loss to …

Interface debonding is considered as a major reason for loss of well integrity of a CO 2
injector. In this work, a 3D numerical model is developed for simulation of a fluid-driven …

Previous lost-circulation models assume either a stationary fracture or a constant-pressure-
or constant-flowrate-driven fracture, but they cannot capture fluid loss into a growing …

Refracturing can effectively enhance hydrocarbon production from hydraulically fractured
wells. Using self-degradable diverting agents, people can temporarily plug previously …

Temporary plugging and diverting fracturing (TPDF) has become one of the fastest‐growing
techniques to maximize the stimulated reservoir volume (SRV). During the field operation of …

Casing deformation problems occur frequently during volume fracturing of shale gas wells. It
is crucial to assess the casing deformation near heel (the beginning of the horizontal …

One of the most challenging issues during drilling operations is lost circulation, which can
cause several problems that could lead to increasing the non-productive time (NPT) and …

Cutting rock in pressurized conditions is essentially different as compared to the ambient
conditions. Under pressurized condition, cutter is not only fragmenting the rock matrix, but …

Strength anisotropy is one of the most distinct features of layered formations, but anisotropic
tensile strength has received scarce attention in the prediction of fracture pressure …
