Paper Number: OTC-26188-MS
... Abstract The problem of lost circulation occurs almost permanently during drilling operations. When drilling highly permeable, highly fractured, and depleted zones, large drilling fluid losses lead to increased operational expenses. Lost circulation may have several consequences, including...

..., but can also accrue expensive non-productive time (NPT) in trying to arrest the losses. Once a lost circulation event occurs, it is recommended to apply the appropriate fluid solution as quickly as possible to help minimize NPT and maximize wellbore value. Using an engineering model to estimate large...
