Umbhobho wepetroleum okhethekileyo usetyenziswa kakhulu ekugrumbeni imithombo yeoyile negesi kunye nokuhambisa ioyile negesi. Ubandakanya umbhobho wokugrumba ioyile, isingxobo seoyile kunye nombhobho wokumpompa ioyile. Umbhobho wokugrumba ioyile usetyenziselwa ukudibanisa ikhola yokugrumba kwi-drill bit kunye namandla okugrumba okudlulisa. Isingxobo seoyile sisetyenziselwa kakhulu ukuxhasa udonga lomngxuma ngexesha lokugrumba nasemva kokugqitywa, ukuqinisekisa inkqubo yokugrumba kunye nokusebenza okuqhelekileyo komngxuma wonke emva kokugqitywa. Umbhobho wokumpompa ngokuyintloko uhambisa ioyile kunye negesi ukusuka ezantsi komngxuma ukuya kumphezulu.

Ibhokisi yeoyileyindlela yokuphila yokusebenza kwequla leoyile. Ngenxa yeemeko ezahlukeneyo zejoloji, imeko yoxinzelelo olungaphantsi komhlaba iyinkimbinkimbi, iyaxina, iyaxina, iyagoba kwaye ibangela uxinzelelo olujikelezayo emzimbeni wombhobho, nto leyo ebeka phambili iimfuno eziphezulu kumgangatho wequla ngokwalo. Ukuba iqula ngokwalo lonakele ngesizathu esithile, lonke iqula linokuncipha imveliso okanye lishiywe.

Ngokwendlela intsimbi enamandla ngayo, i-casing inokwahlulwahlulwa ibe ziintlobo ezahlukeneyo zentsimbi, oko kukuthiJ55, K55, N80, L80, C90, T95, P110, Q125, V150, njl. Iimeko ezahlukeneyo zemithombo, ubunzulu bemithombo, ukusetyenziswa komgangatho wentsimbi nako kwahlukile. Ibhokisi ngokwayo ikwafuneka ukuba ibe nokumelana nokugqwala kwindawo enokugqwala. Endaweni yeemeko zejoloji ezinzima, ibhokisi ikwafuneka ukuba ibe namandla okumelana nokuwa.
