Stuck pipe is one of the common challenges in drilling operations. It happens when the drill string or drill pipe becomes immobilized and cannot be readily extracted from the wellbore due to several factors like differential pressure, wellbore geometry, formation conditions, or mechanical problems.
On the other hand, a fishing operation refers to a formal procedure conducted to recover equipment or tools that have been lost or become stuck in the wellbore during drilling operations. Both stuck pipe prevention and fishing operations aim to address challenges encountered during drilling operations in the oil and gas industry, ensuring the continuity of the drilling process.
