  • Lost circulation was frequently encountered in the complex formations in Misan Oilfield in Misan Province of Iraq. Lost circulation, especially those occurred in the reservoir formations, cannot be stopped using conventional techniques. When drilled the Well AGCS27 to 2,932 m, lost circulation occurred, and was not able to be completely controlled after trying various lost circulation materials (LCM) for 20 times. Finally, a casing barrel was used to transfer the large particle, long fiber LCM to the thief zones, and the lost circulation was successfully stopped. As an economic and practical method of lost circulation control, this technology is worth trying in drilling deep wells with fracture-induced lost circulation.
