Umuyoboro w'icyuma utagira ikizinga usobekeranye n'ibyuma byose bizengurutse, hejuru y'umuyoboro w'icyuma utarinze gusudira, witwa umuyoboro w'icyuma udafite kashe.Ukurikije uburyo bwo kubyaza umusaruro, umuyoboro wibyuma udafite uburinganire urashobora kugabanywamo ibyuma bishyushye bidafite icyuma, icyuma gikonjesha icyuma gikonjesha, icyuma gikonjesha gikonje kidafite icyuma, icyuma gisohora ibyuma bidafite icyuma, imiyoboro y'amashanyarazi, n'ibindi. Ukurikije imiterere y'igice, ibyuma bidafite icyerekezo umuyoboro ugabanijwemo uruziga kandi rudasanzwe, rufite imiterere yihariye ifite kare, oval, mpandeshatu, impande esheshatu, imbuto ya melon, inyenyeri, umuyoboro wamababa hamwe nuburyo butandukanye.Diameter ntarengwa ni 900mm naho diameter ntarengwa ni 4mm.Ukurikije uburyo butandukanye, hariho urukuta rwinshi rutagira umuyoboro wicyuma hamwe nicyuma cyoroshye kitagira icyuma.Umuyoboro w'icyuma udafite icyerekezo gikoreshwa cyane cyane nka peteroli ya geologiya yo gucukura, umuyoboro wa peteroli ukomoka kuri peteroli, umuyoboro wo gutekesha, gutwara imiyoboro n'imodoka, romoruki, indege ibyuma byubatswe neza.
