Drillpipe rotating inside a well`s intermediate string of casing has long been recognized as the principal cause of internal casing wear. Because today`s wells are longer and deeper than ever, prolonged contact can cause sufficient wear to either breach the casing or weaken it to the extent that it will rupture when the casing is pressure tested, delaying the project while an unplanned tieback casing string is installed. Based on more than 300 casing wear experiments, a computer program was developed to calculate the potential for casing wear during drilling operations. Taking proper precautions can save operators more than $1 million per well.
