Ukubulala okuninzi sisixhobo esiyimfuneko sokulawula ukuphuphuma kunye nokuvuthela, kunye nokuphumeza iteknoloji yokulawula uxinzelelo kwimithombo yeoli kunye negesi.
Ngethuba lenkqubo yokugaya i-oyile kunye negesi yegesi, emva kokuba i-drilling fluid kwi-wellbore ihlanjululwe ngumbane wokwakheka, ibhalansi phakathi koxinzelelo lwekholamu yolwelo olumileyo lwe-drilling fluid kunye noxinzelelo lokubumba luya kuphazamiseka, olukhokelela ekuphuphumeni kunye nokuvuthela.
Xa kuyimfuneko ukujikelezisa ulwelo olungcolileyo lokumba okanye ukupompa amaqula e-hydraulic kunye nokusebenza okuhlengahlengisiweyo ukuze kwakhiwe obu budlelwane bokulinganisela, kodwa ukujikeleza okuqhelekileyo akunakufezekiswa ngomtya wokubhobhoza, ulwelo lokubhola kunye nokusebenza okuhlengahlengisiweyo kunokumpontshelwa equleni bulala ngokuphindaphindiweyo ukulawula uxinzelelo lwe-oyile kunye negesi kakuhle.
