Abstract
Fiber optic sensing systems and methods. In a described embodiment, a fiber optic sensing system includes an optical fiber transmitting energy to a chemical vapor deposited diamond material proximate a substance in a well. The diamond material is deposited as a coating on a substrate. The substrate and coating are heated when the energy is transmitted by the optical fiber. This heats the substance in the well, which is detected to determine a property of the substance. In another embodiment, light energy is transmitted through the diamond material.

14. A fiber optic sensing system for use in detecting at least one property of a substance or heat transfer characteristic of a location proximate to the substance in a subterranean well, the sensing system comprising:
-
an optical fiber for transmitting energy to a sensor surface, the sensor surface being heated as a result of the energy transmitted by the optical fiber; and a first temperature sensor for detecting a temperature of the substance as heated by the sensor surface. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)
