Chitoliro chachitsulo cha Petroleum (GB/T9948-88) ndi chitoliro chachitsulo chosasokonezeka choyenera ng'anjo yamoto, chotenthetsera kutentha ndi payipi mumafuta opangira mafuta.

Chitoliro chachitsulo cha pobowola geological (YB235-70) chimagwiritsidwa ntchito pobowola pachimake ndi dipatimenti ya geological, yomwe imatha kugawidwa mu chitoliro chobowola, kolala yobowola, chitoliro chapakati, chitoliro cha casing ndi chitoliro cha mpweya malinga ndi ntchito yake.
