DIELECTRIC CONTRAST AGENTS AND METHODS |
| 摘要 |
Contrast agents and methods for use in geological applications are provided. Contrast agents can be a nanopolymorph material, such as titania nanotubes, and have a low-frequency dielectric permittivity. Methods of identifying one or more subterranean features during geological exploration are provided. Methods of identifying a ganglion of bypassed oil are provided. Methods of illuminating subterranean fractures in hydraulic fracturing are provided. |

1. A method of identifying a subterranean feature, comprising:
administering a contrast agent into a geological site, wherein the contrast agent comprises a nanopolymorph material having a low-frequency dielectric permittivity; allowing the contrast agent to migrate to a subterranean feature in the geological site; and illuminating the subterranean feature using an electromagnetic tool suitable for sensing a presence of the contrast agent that has migrated to the subterranean feature. |
