... for refracturing. At that time, it was considered that refracturing was to reopen the closed cracks or further extend the original fracturing cracks. Until the middle and late 1980s, with the change of international oil price and the development of modern hydraulic fracturing technology, refracturing treatment has...

In this work, we present exact 3D simulations of hydraulic fracture propagation, followed by fracture closure as a result of shut-in and after-closure reservoir flow. The simulations focus on the details of valve closure at the wellhead...
