Casing: Feem ntau yog siv los kaw qhov tsim thiab txhim kho cov phab ntsa zoo kom tsis txhob muaj cov kua dej ntws tawm thiab tsim los ntawm kev nyem lub qhov dej.
Roj pipeline: Nws yog lub raj xa dej uas thauj cov roj av thiab cov nkev los ntawm cov roj thiab roj txheej mus rau saum npoo tom qab drilling tiav, tsim cov channel ntawm cov roj av hauv av thiab cov roj av thiab qhov chaw.
Laum yeeb nkab: Nws yog ib feem ntawm txoj hlua xyaum. Nws lub luag haujlwm tseem ceeb yog xa cov torque, thauj cov dej drilling, txuas thiab loj hlob txoj hlua xyaum, thiab ua kom lub qhov dej tob tob.
