Abstract: A method for identifying anomalous mud flow includes determining an operating rate of a mud pump discharging to a pipe string in a wellbore. Mud returned from the wellbore is moved to a first metering tank. Mud is moved from the first transfer tank to a mud storage tank using a first pump having a flow rate directly related to an operating rate thereof. A first parameter related to volume of mud in the first metering tank is measured. Anomalous mud flow is identified by detecting changes in the operating rate of the first pump wherein the operating rate is adjusted to maintain the first parameter substantially constant.
