I-Hydraulic fracturing, evame ukubizwa ngokuthi i-fracking, iyindlela yokuvuselela imithombo kawoyela negesi esishintshe kakhulu imboni kawoyela negesi emashumini eminyaka adlule. Le nqubo ihilela ukujova ingxube yomuthi woketshezi onomfutho ophezulu emafungweni omhlaba ukuze kwakheke imifantu, okwenza ukuthi ama-hydrocarbon abanjisiwe ageleke kalula emgodini. Le ndlela isetshenziswa ikakhulukazi emithonjeni enomfutho ophansi njenge-shale, i-tight sand, kanye namafungwo e-coalbed methane, lapho ukugeleza kwemvelo kunganele ukukhiqiza kwezentengiselwano. Ngaphandle kwe-hydraulic fracturing, amavolumu amakhulu kawoyela negesi yemvelo angahlala evalelwe ejulile emhlabeni, angatholakali ngezindlela zokumba ezijwayelekile. Ukwamukelwa kabanzi kwezinto zokusebenza ze-fracturing kuvule izinsiza zamandla ezazibhekwa njengezinganenzuzo, kuguqule kakhulu izimakethe zamandla zomhlaba wonke. Namuhla, i-hydraulic fracturing ubuchwepheshe obuyisisekelo kubakhiqizi bamandla emhlabeni wonke, obuvumela ukutholwa kwezinsiza ezisekela imiphakathi yezimboni yesimanje.

Imvelaphi ye-hydraulic fracturing ibuyela emuva ngasekupheleni kwawo-1940 lapho kwenziwa khona ukwelashwa kokuqala kwezohwebo e-Kansas. Kusukela lapho, ubuchwepheshe buye bathuthuka ngokusebenzisa ukuqanjwa okusha njalo kumakhemistri woketshezi, izinto ze-proppant, kanye nezingqikithi zokuqapha. Imisebenzi yesimanje yokuhlakaza iyimibono eyenziwe kahle kakhulu ehlanganisa imodeli ye-geological, ukuqoqwa kwedatha yesikhathi sangempela, kanye nesayensi yezinto ezithuthukisiwe ukuze kuthuthukiswe i-fracture geometry kanye ne-conductivity. Ubukhulu bemikhankaso yokuhlakaza yesimanje bumangalisayo, lapho abaqhubi beqhubeka kaningi namashumi ezinkundla emgodini owodwa ovundlile, inkundla ngayinye idinga ukulawulwa okunembayo kwe-pressure, i-flow rate, kanye ne-chemical composition. Lolu shintsho luqhutshwe isidingo sokukhiqiza ama-hydrocarbon kusuka ezakhiweni eziyinkimbinkimbi ngokwengeziwe ngenkathi kugcinwa ukusebenza kahle kwezomnotho kanye nokuphepha kokusebenza.
