Cov txiaj ntsig ntawm kev sib hloov siab ceev:
Kev Nkag Mus Rau Cov Nqi Nkag Rau Hauv Mos Muag Rau Nruab Nrab -} tawv formations
Txo me ntsis hnav vim yog rau smoother pob zeb txiav
Kev tswj hwm zoo ntawm cov kev taw qhia ntawm borehole (tshwj xeeb tshaj yog nyob rau hauv daim kab rov tav drilling)
TSEEM CEEB TSEEM CEEB:
Kev sib hloov ceev yuav tsum tau phim cov hom me me, pob zeb hardness, thiab txoj kev drilling. Kev kub dhau heev hauv pob zeb nyuaj heev tuaj yeem ua kom lub plab me me lossis ua rau hnav thaum ua ntej hnav.
Koj puas xav tau kev pab xaiv cov qauv tshwj xeeb nrog kev sib hloov nrawm nrawm?
