  • REDUCING ASPHALTENES IN PRODUCED FLUIDS FROM A WELLBORE
    Publication number: 20220025735
    Abstract: Embodiments of reducing asphaltenes in produced fluids from a wellbore are provided herein. One embodiment comprises injecting a combination of gas and coated nanoparticles into a wellbore during a gas lift operation. The coated nanoparticles adsorb asphaltenes in the wellbore, thereby inhibiting asphaltene deposition, reducing asphaltene molecule interaction, reducing agglomeration of asphaltenes, or any combination thereof. The embodiment further comprises recovering produced fluids through the wellbore.
