Casing drilling: How the pieces fit ///
Casing drilling permits operators to simultaneously drill, case and evaluate oil and gas wells, thereby significantly reducing drilling time and the potential for unscheduled events. Field studies have demonstrated a 20 – 30% reduction in the time required to drill wells from spud to rig release when utilizing this method. Both onshore and offshore, casing drilling has been demonstrated to improve reservoir productivity. It also simplifies well architecture in deepwater applications by minimizing formation damage and the cost of well construction and intervention.
