Key words: drilling waste, drilled cuttings, waste drilling mud, re-injection, drilling waste disposal.

To identify the most cost-effective solution for the disposal of drilled cuttings in the continental shelf is a critical task for every field operator. The study is to extend previous research on drilling waste disposal business mechanisms. Today, there is no criteria to facilitate field operators’ choice between drilled cuttings re-injection technology or hauling to shore. The purpose of the paper is to identify conditions (the number of wells in a cluster and measured depth) where re-injection would be a more cost-effective choice than hauling to shore for treatment. The research covers wells with measured depth of 1000, 3000, and 4500 meters, located 50, 150, 250 and 350 miles from the onshore supply base.
