Abstract
The present invention relates to nanoparticle smart tags and the use of nanoparticle smart tags in the detection of analyte. In particular, the present invention relates to nanoparticle smart tags that may be used in subgeologic formations to detect analytes of interest in real-time. One embodiment of the present invention provides a method of providing a drilling fluid having a nanoparticle smart tag; and a base fluid; and introducing the drilling fluid in a subsurface geologic formation that has an analyte.
Claims18
A method comprising:
- providing a drilling fluid comprising:
- a nanoparticle smart tag;
- and a base fluid;
- and
- introducing the drilling fluid in a subsurface geologic formation comprising an analyte such that the nanoparticle smart tag interacts with the analyte within the subterranean formation to form a nanoparticle smart tag analyte complex;
- circulating a portion of the drilling fluid to the well surface and collecting a sample of the drilling fluid containing the nanoparticle smart tag analyte complex at the well surface,
- wherein the nanoparticle smart tag interacts with the analyte via a chemical bond or adsorption, and
- wherein the nanoparticle smart tag comprises an analyte-reactive moiety that specifically reacts with the analyte to detect the analyte,
- wherein the analyte comprises at least one material selected from the group consisting of:
- gold, silver, arsenic, iron, lead, uranium, copper, platinum, chromium, calcium, magnesium, mercury, zinc, selenium, molybdenum, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, sulfide, sulfide mineralization deposit, and any combination thereof.
