Abstract
A system that applies a method of knowledge-intensive case-based reasoning, for repair and
prevention of unwanted events in the domain of offshore oil well drilling, has been developed in
cooperation with an oil company. From several reoccurring problems during oil well drilling the
problem of "lost circulation", i.e. loss of circulating drilling fluid into the geological formation,
was picked out as a pilot problem. An extensive general knowledge model was developed for
the domain of oil well drilling. About fifty different cases were created on the basis of
