Enhanced aqueous fluid saturation with gases in wellbores
Background Resource extraction, carbon storage, and enhanced oil recovery increasingly demand advanced methods for achieving high levels of gas saturation in fluids under subsurface conditions, yet current techniques struggle with efficient and precise control. Traditional approaches often rely on co-injection methods that mix gases and liquids at...

Carboxylates and their derivatives for improved hydrocarbon recovery and geological storage of hydrogen and carbon dioxide
Problem Water injection, also called “water flooding,” is the most widely used method to increase production from oil reservoirs. It usually follows the primary produc­tion stage, in which the oil production relies on the reservoir’s natural energy. One of the main factors that affect the efficiency of water flooding is the wettability...
