To ensure that drilling and completion operations can be conducted safely and efficiently, several key factors must be considered: well engineering, well integrity, and unconventional drilling techniques such as managed pressure drilling (MPD). Combining these key factors is important and essential. Well engineering is an important key factor in planning a well, as understanding the well and of how the well is to be drilled and completed is also vital. Well integrity can be defined as understanding the conditions of the well ensuring the reliability of the barriers necessary to detect, contain, and control the flow of fluids within the wellbore and needs to be the main frame of the well concept. Understanding well integrity and the relation with well engineering is important to ensure that the capabilities can be fully utilized to plan, drill, and complete a well. Using a MPD technique in well engineering and well integrity will optimize the drilling and completion program of a well with various hazards such as drilling through narrow window, drilling in loss circulation well, high pressure and high temperature wells, drilling in abnormal pressures, and wild cat exploration wells. This paper will discuss the combination of well engineering, well integrity, and MPD to ensure that the Drilling operation is completed while minimizing non-productive time (NPT) and keeping safety as the priority. Several examples from real results and case studies will be discussed in this paper.
