..., we conduct constant composition expansion (CCE) tests with different CO 2 concentrations using a PVT cell. In phase 2, we visualize CO 2 -oil interactions at reservoir pressure and temperature in a custom-designed visual cell. Then, we conduct SEM/EDS analysis on the solid precipitates in the visual...

..., and conductivity for different mesh sizes and areal concentrations under different fracture closure stresses. Next, the conductivity results are input in an in-house fracture propagation model to simulate the fracture conductivity distribution after foam fracturing. After that, the fracture conductivity...

... Abstract As observed in many shale-gas plays, the produced flowback water is highly saline and the salt concentration increases with time. Several past studies investigated water-rock interactions to interpret flowback chemical data, evaluate reservoir performance, and investigate...

This is possible due to the usage of a highly hydrophobic stationary phase, which is not interacting with the high amount of inorganic ions present in produced waters. In extension to the initial publication the influence of organic acids on the hydration and gelation...
