    Decades later in 1991, the potential of coil tubing to become a major cost saver resurfaced due to metallurgical developments creating higher strength steals and continuous milled tubing (replacing the inferior process of welding each section of tubing together individually). These advances along with the development of thicker diameter coil and more accurate tools for controlling downhole orientation, gave CTD merit for potentially becoming a useful tool in some situations (Kumar, 2011). Applications of CTD Today, coiled tubing (CT) is used for a wide variety of applications such as re-entry drilling, disposable exploration wells, deviated wells, lateral drain holes, hydraulic fracturing screen-outs, clean outs, plugging, slim-hole production tubing, well logging, onshore and offshore pipeline installation, and steam injection enhanced oil recovery. Yet, CT primarily serves as a tool for well workovers and other well maintenance services. Since CT revitalization in 1991, CTD has developed enough to become a viable alternative to conventional drilling in certain situations because of its tremendous time reduction incentive (Leising and Newman, 1993; Yang 1998). Economic Advantages of CTD Coil tubing drilling, when properly used, offers a wide variety of economic advantages over conventional drilling. The central advantage of CTD is its ability to drill underbalanced (closed wellbore) safely. Underbalance drilling results in extremely high rates of penetration not…
