Lapho ukungcoliswa kwe-petroleum kuthinta izindawo ezibanzi zokudonsa amanzi, abaphenyi bangase badinge ukubhekwa kwesikali sokudonsa amanzi kanye nokuthathwa kwamasampula okuphindaphindiwe ngoba ukunyakaza kwamanzi kungathwala izinsalela ngaphezu kwendawo ekhishwe ekuqaleni.

I ukuphathwa kokunukubezeka kuzo zonke izindawo ezinamanzi ikhombisa ukuthi kungani ukuhlonza umthombo, ukuqapha njalo, kanye nezindlela zokulawula ukungcoliswa kwemvelo kumele kusebenze ndawonye ngaphakathi kwezinhlelo zemvelo ezixhumene.

Ukwelashwa kwebhayoloji nakho kungaba nomthelela ekulawulweni kwemfucuza ye-petroleum ezimeni ezifanele, nakuba ukusebenza kokwelashwa kuncike ezintweni ezikhona kanye nezimo zemvelo ezisekela umsebenzi wamagciwane.

I ukusetshenziswa kwe-biotechnology ekulawuleni udoti inikeza umongo owengeziwe wezinqubo zebhayoloji ezingaba nomthelela ekuqhekekeni kwemfucuza ekhethiwe equkethe i-hydrocarbon.

Ngakho-ke ukuphathwa kwemvelo okuphumelelayo kuhlanganisa ukuhlonza umthombo, ukuvimbela ukungcola, ukuqapha, ukwelashwa, ukulungisa, ukubhalwa kwemibhalo, nokuhlola kwesikhathi eside kunokuncika endleleni yokuhlaziya eyodwa kuphela.

Ukumaka uwoyela kunokwethenjelwa kakhulu lapho abaphenyi behumusha amaphethini e-biomarker yokuxilonga eduze kwekhemistri ye-petroleum evamile, ukubhekwa kwemvelo, ulwazi lwe-geological, amasampula amele, kanye nezinsiza ezifanele zokubhekisela.

Inani layo lisemandleni ekusizeni ukuxhumanisa izinsalela ze-petroleum nemithombo okungenzeka ibe khona kuyilapho kubalwa izinguquko ezenzeka ngemva kokuba uwoyela ungene ezinhlelweni zemvelo.

Ngenxa yokuthi asikho i-biomarker eyodwa efakazela bonke ubudlelwano bomthombo, ukuhumusha okuphrofeshinali kufanele kuqhathanise izinkomba zamangqamuzana amaningi futhi kuvume ukungaqiniseki noma nini lapho izici zomthombo zigqagqana.

Uma kusetshenziswa ngokucophelela, izigxivizo zeminwe ze-biomarker zinikeza isisekelo esiwusizo sesayensi sokuqapha ukungcoliswa kukawoyela, uphenyo lwezemvelo, ukuhlela ukulungisa, nokuqonda okuthuthukisiwe kokungcoliswa kwe-petroleum.

Isifinyezo Sokumaka Kawoyela kanye Nezimpawu Zezinto Eziphilayo Zokuqapha Ukungcola Kawoyela
