Abstract

This invention relates to a method and system for detecting the condition of a well. During tripping the drilling fluid in the well is controlled to provide an early warning indication of an abnormality in the well. The volume of solid materials moved during each trip is measured and a corresponding required volume of drilling fluid is determined. A measured volume of drilling fluid is delivered in order to restore in the well the drilling fluid to a reference level. The required volume is compared with the measured volume to obtain signals which are indicative of the condition of the well.
