Mineral scale deposition in near wellbore regions of injection wells is one of the main challengeable issues during the water injection process, which magnifies the importance of robust models in predicting the amount of mineral scale deposition such as calcium sulfate. One of the main challenges of CaSO4 scale is in carbonated reservoirs, in which sensitive behavior is observed in related to t...

in this study, a pellet scale model was developed for trickle bed reactor utilizing cfd techniques. drag coefficients were calculated numerically at different velocities and bulk porosities in the case of single phase flow through the dry bed. the simulation results were then compared with the prediction of kozeny-carman (k-c) equation. the results indicated that drag coefficients calculated fr...

Researchers developed an earthquake prediction software and evaluated its performance. This is suitable for short-term prediction. approach relies on the deep involvement of water vapors that occur just before caused by a decrease in pressure increase temperature, leading to 70.5% accuracy within month Japan. In addition, we have tried develop new practical method warn earthquakes not only Japa...

Multi-scale equivariant representations overcome the nearsightedness of local machine-learning approaches.
