A North Sea operator needed to plug and abandon (P&A) a well. The plan was to section mill 9⅝-in casing in open hole. NORSOK regulations stipulate that a 165-ft (50-m) window for a cement plug is required for each hydrocarbon zone in the wellbore. To meet this regulation, two cement plugs were planned, one from 12,078 to 12,243 ft (3660 to 3710 m) measeured depth (MD), and one from 13,140 to 13,305 ft (3982 to 4032 m) MD, with maximum inclinations of 76º and 83.5º, respectively.
