All Aqueous Nano-Emulsion for Acid Stimulation of Oil and Gas Reservoirs
Author(s): Humberto Oliveiraa*, Claudio Pintob and Antonio Peres
Fluids consisting of two immiscible aqueous phases are called Aqueous Biphasic Systems (ABSs). ABSs can form
Water in Water (W/W) emulsions when an "emulsifier" is added to the mixture; they are gradually becoming more
prominent due to lower prices and better alignment with environmental policies compared to Oil in Water (O/W) or
Water in Oil (W/O) emulsions. Still, the understanding of suitable "emulsifiers" for W/W emulsions is still in the
early stages and it is usually a challenge related to very low interfacial tensions and thick water-water interfaces. This
paper presents a new case of successfully stabilized W/W emulsion originated from an ABS system using a completely
new chemical package concept as the “emulsifier”. This innovative W/W emulsion, that also happened to be a nano
emulsion, was created with the objective of bei.. View more»
