System and method of monitoring flow in a wellbore |
摘要 |
A system and method for releasing a marker within a wellbore. The system and method includes a sensor that detects movement or a position of the marker within the wellbore. The marker may be released in drilling fluid, for example, and may travel from the surface to the drill bit and return to the surface with cuttings. As an example, the markers are used to determine the flow of cuttings within the wellbore. |
