A simulation with a compositional model, composed of a graphical front end and readily available commercial simulator software, improved the optimization of gas lift in oil wells when compared with ...

A simulation with a compositional model improved the accuracy when compared with a black-oil model for predicting the performance of gas-lift wells in the Aghajari oil field in Iran. The Marun oil ...

Earth's core is less dense than iron, and therefore it must contain "light elements," such as S, Si, O, or C. We use ab initio molecular dynamics to calculate the density and bulk sound velocity in ...

Scientists have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to its core-mantle boundary, some 1,800 km beneath ...
