Izizathu zokuthi kungani umshini wokubhoboza ojikelezayo usetshenziswa kabanzi ekwakhiweni kobunjiniyela yilezi ezilandelayo:
1. Isivinini sokwakhiwa kwe-rotary drilling rig sishesha kunese-general drilling rig. Ngenxa yezimpawu zesakhiwo senqwaba, indlela yokushaya ayisetshenziswa, ngakho-ke izoba ngokushesha futhi isebenze kahle kune-general pile driver esebenzisa indlela yokushaya.
2. Ukunemba kokwakhiwa kwe-rotary drilling rig kuphakeme kunokwe-general drilling rig. Ngenxa yendlela yokumba ejikelezayo esetshenziswa yinqwaba, uma kwenzeka ukushayela endaweni eqondile, ukunemba kokushayela endaweni eqondile kwenqwaba kuzoba phezulu kunokushayela kwenqwaba evamile.
3. Umsindo wokwakhiwa kwe-rotary drilling rig uphansi kunowe-rotary drilling rig evamile. Umsindo we-rotary drilling rig uvela kakhulu enjinini, kanti eminye i-drilling rig ihlanganisa nomsindo wedwala elishayayo.
4. Udaka lokwakha lwe-rotary drilling rig luncane kunolwe-general drilling rig, olusiza kakhulu ekuxazululeni izindleko kanye nokuvikelwa kwemvelo.
