MPD (Doolista cadaadiska la maareeyay) Qeexitaannada IDC waa habka qodista la qabsiga ee loo isticmaalo in si sax ah loo xakameeyo astaanta cadaadiska sannadlaha ah ee ceelka. Ujeedooyinka waa in la hubiyo xadka deegaanka cadaadiska godka hoose iyo in la maareeyo astaanta cadaadiska biyaha ee anular si waafaqsan. MPD waxaa loogu talagalay in laga fogaado qulqulka joogtada ah ee dareeraha samaynta ee dusha sare. Ku soo qulquli kasta oo shil ah oo ku yimaada hawlgalka si badbaado leh ayaa loo ilaalin doonaa iyadoo la isticmaalayo habab ku habboon.
Shirkaddayada oo ah bixiye adeeg u qalma MPD (Managed Pressure Drilling) tignoolajiyada CNPC iyo CNOOC, tan iyo markii la bilaabay adeegyada tignoolajiyada MPD ee Halliburton ee Shiinaha 2010, waxaanu ururinay wadar ahaan 25 adeegyada tignoolajiyada MPD ee CNPC ee 13 ee la soo dhaafay sano, oo ay ku jiraan 8 ceel oo qoto dheer oo ka badan 8000 mitir.
Hadda, shirkadeena waxay leedahay koox adeeg farsamo oo ka badan 60 shaqaale ah, oo ay ku jiraan 17 injineero leh in ka badan 10 sano oo waayo-aragnimo ah adeegyada MPD iyo 26 injineero leh in ka badan 5 sano oo waayo-aragnimo MPD ah. Waxay u taagan tahay mid ka mid ah bixiyeyaasha adeegga tignoolajiyada MPD ee ugu awoodda badan Shiinaha.
