Abstract Drilling technologies has been developing and evolving ever since the discovery of oil to the human kind. Many reasons encouraged this development, the vast investment and the time to come up and the slightest maturing of this field of science. One of the major yet simplest ways to have one step forward is the ability to use two or multiple technologies in purpose of mitigating each other’s flows and cons. Conventional drilling methods have been a blast to the world of drilling, yet, they have their share of flaws such as tripping in and out operations, pipe handling, and some of these flaws might lead to an actual risk of well control problems. Thus, it was a motive to innovate solutions to attenuate those limitations. Casing drilling technology became a solution for many of the conventional drilling methods imperfections such as narrowing down the tripping operations to the point of no tripping out post reaching the planned depth, which helped reducing time which usual many hours are spent on using conventional methods. As for managed pressure drilling technology, it has proven it benefits on many projects by achieving a safer, more efficient and cost effectiveness. Also, it gives the ability to closely monitor the well and better accuracy determining or detecting aberrations encountered, thus an enhanced response capability. In this case study, several mud losses in different depths varying between partial and complete mud loss, and also a premature casing seat and pipe stuck problem occurred. All combined lead to a major non-productive time which increased the overall time spent and the cost dramatically. This thesis will focus on implementing both managed pressure and casing drilling technologies since both technologies proved worldwide their applicability for overcoming the problems encountered in this case study, which conventional drilling method was used in. The well hydraulic analysis and economical assessment of new technologies are provided and eventually conclude the outcome of applying the managed pressure casing drilling together.
