 Abstract
This paper describes the new drilling riser-less concept for deepwater operations that will remove some of the well control challenges and limitations currently experienced when handling kicks and deep formation gas flow into a well being drilled. There are analyzed the differences between the conventional drilling system and the MPD system, the benefits and the disadvantages of the MPD method. Also the paper presents a case study were the MPD system was used successfully.

 Rezumat
În lucrare se prezintă un concept nou de foraj fără riser pentru operaţiunile de mare adâncime, concept ce înlătură unele din problemele şi limitările legate de controlul găurii de sondă, probleme ce sunt întâmpinate în prezent, în cazul unei erupţii sau unei migrări de gaze la suprafaţă, în timpul forajului. Sunt analizate diferenţele dintre forajul convenţional şi forajul cu presiune controlată, dar şi beneficiile şi dezavantajele sistemului de foraj cu presiune controlată. Deasemenea în lucrare este prezentat un studiu de caz unde sistemul de foraj cu presiune controlată a fost aplicat cu succes.
