Abstract
Summary
In order to achieve the objective for drilling a new section in the well and due to the current scenario , the only alternative was to open a side-track through three casings sizes 11 7/8 “71 lb/ft – 13 3/8 “72 lb/ft - 16” 109 lb/ft, which represented a great challenge for both companies.
