Abstract
A method for determining conditions in a wellbore extending through a subterranean formation includes deploying a plurality of sensor pods in the wellbore, wherein each sensor pod includes a housing and a plurality of sensors disposed in the housing. The method also includes measuring and recording a plurality of pressures and a plurality of temperatures with plurality of sensors of each sensor pod, dissolving the housings of the pods to release the plurality of sensors from the pods after measuring and recording the plurality of pressures and the plurality of temperatures, and lifting the sensors to the surface.
