Uwoyela negesi kwakhiwe ngezinsalela zezinto eziphilayo ezibolile edwaleni le-sedimentary kanye namaminerali edwala.Lapho lawa matshe egqitshwa inzika egcwele ngokweqile, i-organic matter iyabola futhi iguqukele ekubeni uwoyela negesi yemvelo ngezinqubo zebhaktheriya ezihambisana nokushisa okuphezulu nokucindezela.Ngaphezu kwalokho, uwoyela negesi kanye namanzi kuyafuduka edwaleni kuya edwaleni eliseduze lechibi (okuvame ukuba ngamatshe esihlabathi, i-limestone, noma ama-dolomite).Ukunyakaza kuyaqhubeka kuze kube yilapho behlangana nedwala elingenakunyakaziswa.Ngenxa yomehluko wokuminyana, igesi itholakala phezulu ilandelwa uwoyela namanzi;indawo yokugcina uwoyela ivezwe kuMfanekiso 1-2 okhombisa izendlalelo ezihlukene ezakhiwe yigesi, uwoyela namanzi.
Ngemva kokuba inqubo yokuhlola nokugaya uwoyela ifinyelelwe, ngesikhathi sokukhiqizwa kukawoyela negesi, kunezindlela ezintathu ezihlukene zokubuyisela ezisetshenzisiwe;amasu okutakula okuyisisekelo, okwesibili nasezingeni eliphezulu.Enqubweni eyinhloko yokubuyisela uwoyela uphoqeleka ukuba udlulele phezulu ngenxa yokucindezela kwedamu, futhi amaphampu angasetshenziswa lapho ukucindezela kuncipha.Izindlela zokubuyisela eziyinhloko zibalelwa ku-10% wokukhiqiza uwoyela [8].Lapho ichibi livuthwa futhi uma engekho amanzi e-aquifer athatha indawo kawoyela okhiqizayo, amanzi noma igesi ijovwe endaweni yokugcina amanzi ukuze kwandiswe umfutho, le nqubo yesi-2 yaziwa ngokuthi ukubuyiswa kwesibili;kuholela ekubuyiselweni kuka-20-40 % kawoyela wasekuqaleni wereservoir endaweni.Umfanekiso 1-3 unikeza incazelo ecacile yamasu okubuyisela okwesibili.
Okokugcina, amasu okuthola kabusha okuphakeme (okungaziwa ngokuthi ukubuyiswa kukawoyela okuthuthukisiwe) abandakanya umjovo wesitimu, isincibilikisi noma i-bacterial kanye nesihlanzi ukuze kuthuthukiswe ukutholakala kukawoyela;Lezi zindlela zenza ama-30-70 % kawoyela wangempela endaweni.Enye yezingqinamba zokusetshenziswa kwamasu amabili okugcina ukuthi kungaholela ekwehleni kokuqinile (isikali).Izinhlobo zezikali ezakhiwe embonini kawoyela negesi kuzoxoxwa ngazo esigabeni esilandelayo.
