Abstract
Given a number of temperature measurements, such as from a Distributed Temperature Sensing System (DTS), at various depths in a wellbore, a derivative of temperature with respect to depth can be calculated. A fluid boundary can then be identified where the depths below the boundary corresponds to the presence of fluid and a low fluctuation regime in the derivative of temperature with respect to depth, and the depths above the boundary correspond to the absence of fluid and a high fluctuation regime in the derivative of temperature with respect to depth.
