"A pulling unit is one of the mechanical oilfield applications used to remove the casing and other tubing apparatuses inside a well bar. It is also used to remove drilling rods inside a wellbore. A pulling unit is called in when a wellbore shows signs of internal damage, such as an obvious leak or a sudden drop in pressure of the drilling fluid at the surface. When a wellbore is displaying production problems that cannot be repaired through more simple means, the pulling unit is charged with physically lifting the casing and any of the drilling equipment that appears to be damaged out of the wellbore to be examined and repaired in a timely manner."
