Shut-in time optimization after fracturing in shale oil reservoirs
A multi-process (fracturing, shut-in and production) multi-phase flow model was derived considering the osmotic pressure, membrane effect, elastic energy and capillary force, to determine the optimal shut-in time after multi-cluster staged hydraulic ...

Numerical Simulation Study on Optimal Shut-In Time in Jimsar Shale Oil Reservoir [PDF]
The volume fracturing technology along with horizontal well is the main technology to obtain commercial oil flow in shale reservoirs because of the low porosity and low permeability.

Hydrodynamic Equilibrium Simulation and Shut-in Time Optimization for Hydraulically Fractured Shale Gas Wells [PDF]
Post-fracturing well shut-in is traditionally due to the elastic closure of hydraulic fractures and proppant compaction. However, for shale gas wells, the extension of shut-in time may improve the post-fracturing gas production due to formation energy ...

Numerical Study on the Effects of Imbibition on Gas Production and Shut-In Time Optimization in Woodford Shale Formation [PDF]
In shale gas formations, imbibition is significant since the tight pore structure causes a strong capillary suction pressure. After hydraulic fracturing, imbibition during the period of shut-in affects the water recovery of flowback.

Confluence and cold shut computation based on time field in casting simulation [PDF]
Numerical simulation technology has been widely used in the foundry industry to analyze and improve casting processes. During the casting filling process, many filling-related defects form easily at the confluences of liquid metal streams.

Early-Time Shut-In for Plane-Strain Hydraulic Fractures [PDF]
AbstractOne investigates the post-shut-in growth of a plane-strain hydraulic fracture in an impermeable medium while accounting for the possible presence of a fluid lag. After the stop of fluid injection, the fracture may present three distinct propagation patterns: an immediate arrest, a temporary arrest with delayed propagation, and a continuous ...

Undergraduate mental health nursing education: Time to shut up? [PDF]
Undergraduate mental health nursing education has dominated the landscape, not only in Australia, but internationally, for decades now. It might prompt thoughts that perhaps we should move on. I disagree. The June editorial by Dianne Wynaden (2011) has got me thinking even more, hence this editorial is about education.

Is it time to get some SHUT-i? [PDF]
There are four central things that are well known about insomnia which together highlight it as a serious public health concern: (I) it is a significant issue - over a third of the population will experience an acute episode (less than three months in duration) of insomnia every year (1) and between 10–20% of the population will report chronic insomnia
