Udupaki tw’imiyoboro dukoreshwa mu bwoko butandukanye bw’udupaki tw’ubushyuhe, nk’udupaki tw’ubushyuhe bw’imashini n’udupaki tw’imiyoboro ndetse n’udupaki tw’ubushyuhe dukonjeshwa n’umwuka. Udupaki tw’imiyoboro tw’imashini twombi duto duto hamwe n’udupaki tw’umwuka twa U bend, dushobora gusimburwa hatabayeho guhindura ubushobozi bwo guhanahana ubushyuhe kandi dushobora kwihuza neza n’imiyoboro n’imiterere isanzweho.

Gusimbuza icyuma gitwara ubwato gifite imyaka 40 (ibinyampeke) byasabaga kuzamura inyubako yo hejuru ya mm 300 kugira ngo hatangwe umwanya uhagije mu gihe cyo gusimbuza. Gukomeza guhuza umuvuduko byatumye bigorana kubungabunga uburinganire bw'icyuma gitwara ubwato mu gihe cyo gusimbuza.

Gukora ku cyuma gipima peteroli biragoye. Imiyaga ikaze n'imvura bishobora kugukurura ku nkombe kandi urusaku rw'imashini ziremereye rutuma wumva urusaku. Ibikorwa byo gucukura bigushyira mu kaga ko gukomereka bikomeye, bigatuma umutekano uba ingenzi cyane.

Ku mushinga uherutse gukorwa na peteroli ugamije guteranya imiyoboro y’amashanyarazi n’ibikoresho byo mu ruziga, gukoresha ibyuma bikoresha amashanyarazi byafashije abakozi b’ubwubatsi kugera ku miyoboro ihamye kandi yizewe.
