Thaum lub sijhawm ua haujlwm, lub hauv paus ntsiab lus "peb qeeb, ib qho ceev" yuav tsum ua raws li: maj mam txo qis ntawm lub laum, qeeb drilling, qeeb nqa lub laum, thiab tshem tawm cov av ceev. Nyob rau tib lub sijhawm, torque thiab kev sib hloov ceev yuav tsum tau tswj raws li qhov sib txawv geological formations. Piv txwv li, hauv av nplaum, kev sib hloov ceev tuaj yeem tswj tau ntawm 20-30 rpm, thiab hauv cov xuab zeb txheej, ntawm 15-25 rpm. Rau kev saib xyuas, kev kuaj xyuas txhua hnub yuav tsum tau ua rau cov tuav cov hniav xoob thiab cov kab nrib pleb. Lubricating roj yuav tsum tau ntxiv txhua 50 teev. Thaum khaws cia, lub laum me ntsis yuav tsum tau muab tshem tawm kom tsis txhob deformation.
