Liquid–liquid gravity displacement in a vertical fracture during drilling: Experimental study and mathematical model

open access: yesEnergy Exploration & Exploitation, 2020
Gravity displacement often occurs when drilling a vertical fractured formation, causing a downhole complexity with risk of blowout and reservoir damage, well control difficulty, drilling cycle prolongation, and increased costs.

An adaptive space-time phase field formulation for dynamic fracture of brittle shells based on LR NURBS [PDF]

open access: yes, 2020
We present an adaptive space-time phase field formulation for dynamic fracture of brittle shells. Their deformation is characterized by the Kirchhoff–Love thin shell theory using a curvilinear surface description.
