Liner rotation during cementing has resulted in more successful primary cement jobs. For more than a year, every liner cemented by Conoco Inc. in the Grand Isle and West Delta areas offshore Louisiana was rotated during cement placement. This resulted in a dramatic reduction in the number of zone isolation squeezes and liner top squeezes. Savings of $140,000/well were achieved if the liner was rotated during cementing. This cost savings was gained as a result of fewer remedial squeeze cementing jobs. This paper presents liner cementing information that details this technique, with emphasis on liner length, depth and hole angle, centralizer and scratcher program, cement and spacer design, and on-site tips for success.
