WELLBORES INCLUDING CARBON QUANTUM DOTS, AND METHODS OF FORMING CARBON QUANTUM DOTS

摘要

A system for determining at least one property of at least one fluid in at least one subterranean formation comprises a fluid delivery system configured and positioned to deliver a fluid into at least one of at least one subterranean formation and a wellbore extending through the at least one subterranean formation. The system comprises a radiation source within the wellbore, the radiation source configured to generate excitation radiation, carbon quantum dots disposed in the fluid, and a detector within the wellbore, the detector configured to measure at least one fluorescence property of the carbon quantum dots. Related methods of determining a property of a wellbore and methods of forming the carbon quantum dots are also disclosed.

1. A system for determining at least one property of at least one fluid in at least one subterranean formation, the system comprising:
a fluid delivery system configured and positioned to deliver a fluid into at least one of at least one subterranean formation and a wellbore extending through the at least one subterranean formation; a radiation source within the wellbore, the radiation source configured to generate excitation radiation; carbon quantum dots comprising a carbon core, the carbon core exhibiting at least one fluorescence property disposed in the fluid; and a detector within the wellbore, the detector configured to measure the at least one fluorescence property of the carbon core.
