Geochemical modeling of the evaporation process in salinized reservoirs in the semi-arid region of Northeastern Brazil [PDF]

RBRH, 2022
The geochemical characterization of saline water in reservoirs located in semi-arid regions is an important issue to be addressed, as it allows us to understand the deterioration of water quality caused by evaporation.

Geochemical Modelling of the Fracturing Fluid Transport in Shale Reservoirs

Energies, 2022
Field operations report that at least half of the fracturing fluid used in shale reservoirs is trapped. These trapped fluids can trigger various geochemical interactions. However, the impact of these interactions on well performance is still elusive.
