Paper Number: SPE-200507-MS
... difficult to predict the fracture and pore pressure limits on some of the wells. Due to this uncertainty, some operators tend to assume the well problems are related to ballooning/breathing. This assumption leads to drilling issues such as but not limited to stuck pipe, excessive mud losses, and tripping...
