Literature Review on Pratical Approaches for Solving Lost Circulation Problem

Lost circulation is a persistent challenge in drilling operations, occurring in highly permeable,
depleted, fractured, or cavernous formations. The uncontrolled loss of drilling fluid into
surrounding formations leads to significant financial and operational setbacks, including rig
downtime, stuck pipe, blowouts, and potential well abandonment. This study comprehensively
reviews existing lost circulation control methods, assessing their successes and limitations in
field applications. Various lost circulation materials (LCMs) and techniques, such as bridging
and plugging agents, pretreatments, and wellbore strengthening, are examined to determine their
effectiveness under varying downhole conditions. Findings indicate that multiple factors,
including borehole pressure, temperature, depth, and the nature of the thief zone influence lost
circulation control. While no single solution can eliminate lost circulation, preventive
strategies— particularly for induced fractures—can significantly mitigate the issue. Practical
guidelines and a reference flowchart developed in this study offer drilling personnel valuable
tools to enhance lost circulation management at the well site.
