Proven Single-Trip 14″ Heavy-Wall Q-125 Casing Exit Using the TrackMaster™ Whipstock System

During a Deepwater Gulf of America (GoA) campaign, Wellbore Integrity Solutions (WIS) successfully milled a single‑trip window in uncemented 14‑in., 115‑ppf Q-125 heavy‑wall casing (0.82‑in. wall thickness). The operation enabled smooth directional BHA pass‑through and uninterrupted continuation of drilling operations. This application required precise window placement and consistent milling performance in heavy‑wall casing.
