Abstract
Methods of monitoring various downhole conditions are described, including a system for determining and/or identifying the flow of fluid in a well, determining sand production in a well, identifying localized events in a well, determining the apparent flow velocity of fluid flowing through a downhole conduit, and/or monitoring the strain in downhole tubulars. These determinations may be made by monitoring signals received from one or more sensors located in a well and analysing the signals, such as their frequency and timing.
