Key words: drilling failures, mud loss, cement bridge, fillers and bridging agents.
The paper provides the results of introducing new technologies for drilling failure response in Chayandinkoye oil and gas condensate field. The main drilling problem is mud losses of various intensity, including catastrophic mud losses. The basic measure to prevent catastrophic losses of drilling fluid is the installation of cement bridges containing various combinations of fillers and bridging agents. Drilling failure response procedures have been developed, based on the technologies and materials which were successfully used whilst drilling.
