Izibhamu eziqhuma isikhathi eside zidlala indima ebalulekile esimweni esibanzi sokuqedwa komthombo kawoyela negesi, okunomthelela ekwandiseni ukukhiqizwa kanye nenzuzo. Lawa mathuluzi asetshenziselwa ukudala izimbobo ku-casing kanye nokwakheka okuzungezile, okuvumela ukugeleza kwama-hydrocarbons ukusuka ku-reservoir ukuya emgodini womthombo.
Ngokusebenzisa izibhamu ezimbobozelayo ezinde, opharetha bangakwazi ukubeka amashaji amise ngendlela ehlelekile ekujuleni okuthile eduze komthombo. Uma ziqhunyiswa, lezi zindleko zingena emgodini kanye nokwakheka, zenze imigudu yokuthi ama-hydrocarbon agelezele emthonjeni. Le nqubo yaziwa ngokuthi yi-perforation.
Izinga nokusebenza kahle kokubhobozwa kunomthelela ngokuqondile ekukhiqizeni komthombo. Izimbobo eziklanywe kahle nezibekwe kahle zivumela ukuthintana kwedamu, okuthuthukisa izinga lokukhiqizwa kukawoyela negesi. Ngokulungisa izindlela zokugeleza, izibhamu eziqhumayo ezinde zinomthelela ekwandeni komkhiqizo kanye namazinga okuthola kabusha athuthukisiwe.
Ngaphezu kwalokho, izibhamu ezinde ezibhoboza zivumela abaqhubi ukuthi bakhombe izindawo ezithile ngaphakathi kwechibi, njengezindawo ezinokugcwala okuphezulu kwe-hydrocarbon noma ukungeneka okukhulu. Le ndlela yokubhoboza ekhethiwe isiza ukwandisa amandla okukhiqiza omthombo ngokugxila ezinkathini ezikhiqiza kakhulu.
Ukwandisa ukukhiqizwa kanye nenzuzo embonini kawoyela negesi kuncike kakhulu ekuqedeni kahle kwemithombo. Izibhamu ezibhobozayo ezinde zidlala indima ebalulekile kule nqubo ngokuqinisekisa ukufinyelela okusebenzayo kwedamu nokuthuthukisa ukugeleza kahle. Ngokwenza lula ukukhishwa kwama-hydrocarbons echibini, lawa mathuluzi afaka isandla ekusebenzeni komnotho okuphelele komthombo kanye nempumelelo yokusebenza.
Kafushane, izibhamu eziqhumayo ezinde zibalulekile ekusebenzeni kokuphothula kahle embonini kawoyela negesi. Asebenza ukudala ukubhoboza okwenza kube lula ukugeleza kwama-hydrocarbons ukusuka endaweni yokugcina amanzi kuya emthonjeni. Ngokwandisa ukuthintana kwedamu nokukhomba izindawo ezithile, lawa mathuluzi athuthukisa amanani okukhiqiza, athuthukise ukutholwa, futhi ekugcineni abe nesandla enzuzweni nasempumelelweni yokusebenza kukawoyela negesi.
