Follow up study of MPD successful application

The international association of drilling contractors (IADC) defined 2 categories of the Managed Pressure Drilling (MPD) reactive MPD includes drilling programs that are tooled up with at least a rotating control device (RDC), choke, and perhaps drill string float to safely and efficiently deal with problems that could occur downhole. Proactive MPD includes designing a casing, fluids and openhole program that precisely manages the wellbore pressure profile. With these categories of MPD can offer the greatest benefit to the offshore drilling industry as it can deal with foreseen problems before they occur.

Couple with the experience in the offshore drilling the MPD has proved that with its latest technology that can mitigate the drilling related - issue. However, to quantify the MPD application there must be a follow-up study in order to quantify the MPD application. And also study must follow up in order to select the MPD techniques to drill in the isolate environment, one of them is Timor Sea, as Timor Leste is a virgin country in term of technology and the wells history or drilling histories of the fields therefore it is important if researchers looked at some other alternatives in regard with this issue.

In addition, in regard of the Non-Productive Time (NPT) the study also requires to indentify the number of days reduced using MPD, with that we will ascertain to estimate the drilling cost, it helps to avoid over estimated of Authorized for Expenditure (AFE)and also the researchers need to look at the cheaper technology for selecting the MPD this is including the use of simple modelling which the existence computer program to simulate the program therefore it won't take any longer in selection of the MPD's techniques.
