Energy Science &Engineering, Volume 14, Issue 1, Page 489-500, January 2026.ABSTRACT Effective hole cleaning is essential to drilling success, with poor cuttings transport leading to reduced penetration rates, stuck pipe, and increased non‐productive time. The Drilling Cuttings Carrying Index (CCI) indicates the efficiency of hole cleaning. To ensure optimal hole cleaning, it should be greater than or equal to 1.
