I-petroleum ekhethekileyo isetyenziselwa ikakhulu kwi-oyile kunye negesi yegesi kakuhle kunye neoyile kunye negesi. Ibandakanya umbhobho wokuqhuba ioyile, i-oyile ecide kunye nombhobho wokumpompoza ioyile. Umbhobho we-oyile ye-oyile usetyenziselwa ukudibanisa i-Drill Collar kwi-drill bit kunye nokudlulisela amandla okuqhuba. Ukushenxisa kweoyile ikakhulu kusetyenziswa ikakhulu ukuxhasa udonga olufanelekileyo ngexesha lokuqhuba nangemva kokugqitywa, ukuze kuqinisekiswe inkqubo yokuqhuba kunye nokusebenza kwesiqhelo emva kokugqitywa. Umbhobho wempompo udlulisela ioyile kunye negesi ukusuka ezantsi kwiqula ukuya kumphezulu.

Ukuthambisa ioyileyindawo yokuphila ye-oyile ioyile. Ngenxa yeemeko ezahlukeneyo zejografi, imeko yoxinzelelo engaphantsi komhlaba inzima, inamangile, icinezelayo, ukugoba kunye nokugoduka kunye ne-torsor kunye ne-torsional yoxinzelelo kumgangatho wokushenxisa. Ukuba isikhephe ngokwayo siyonakalisile isizathu esithile, iqulatho yonke linokuncitshiswa okanye liyeke.

Ngokwamandla entsimbi ngokwayo, i-cheng inokwahlulwa yangamanqanaba ahlukeneyo ensimbi, oko kukuthiJ55, K55, N80, l80, C90, T95, P110, Q155, v150, njl njl, njl njl. Isikhephe ngokwayo siyadingeka ukuba sixhathise ukuxhathisa i-corosion kwindawo ebonakalayo. Endaweni yeemeko zejografini zejografini, ukufushelwa kukwafuneka kukukwazi ukwamkela ukuwa.
