Iindawo ze-oyile nerhasi- Zinkulu, ziyabiza kwaye ziyinxalenye ebalulekileyo kuqoqosho lwehlabathi.Ngokuxhomekeke kwindawo yentsimi, ixesha, iindleko kunye nobunzima bokugqiba isigaba ngasinye siya kuhluka.
Isigaba sokuLungiselela
Ngaphambi kokuba uqalise uphuhliso lwendawo yeoli kunye negesi, uphando olunzulu kunye novavanyo lubalulekile.Indlela edla ngokusetyenziswa ukuphonononga imithombo ye-oyile nerhasi, uphononongo lwenyikima lubandakanya ukuthumela amaza omsindo ematyeni, ngokuqhelekileyo kusetyenziswa i-seismic vibrator (kuphononongo elunxwemeni) okanye umpu womoya (uphononongo lwaselwandle).Xa amaza esandi egqobhoza kulwakhiwo lwamatye, inxalenye yamandla awo abonakaliswa luqilima lwamatye, ngoxa amanye amandla eqhubeka ngokunzulu kwamanye amacandelo.Amandla abonakalisiweyo athunyelwa emva kwaye arekhodwa.Abasebenzi bophononongo ke ngoko baqikelela ukusasazwa kwe-oyile ephantsi komhlaba kunye nerhasi yendalo, bamisela ubungakanani kunye noovimba bommandla we-oyile nerhasi, kwaye bafunde ubume bomhlaba.Ukongezelela, indawo engaphezulu kunye nezinto ezinokuthi zibe nobungozi kufuneka zihlolwe ukuze kuqinisekiswe ukhuseleko lwenkqubo yophuhliso.
Umjikelo wobomi bendawo yeoli nerhasi unokwahlulwa ube zizigaba ezithathu:
Isigaba sokuqala (iminyaka emibini ukuya kwemithathu): Kweli nqanaba, indawo yeoli nerhasi isaqala ukuvelisa, kwaye imveliso iyanda ngokuthe ngcembe njengoko kusakhiwa ukomba kunye nezibonelelo zemveliso.
Ixesha le-Plateau: Nje ukuba imveliso izinzile, imimandla yeoli nerhasi iya kungena kwixesha lethafa.Ngeli nqanaba, imveliso ihlala izinzile, kwaye eli nqanaba liya kuhlala iminyaka emibini ukuya kwemithathu, ngamanye amaxesha ixesha elide ukuba intsimi yeoli kunye negesi inkulu.
Yala isigaba: Ngeli nqanaba, ukuveliswa kweendawo zeoli kunye negesi ziqala ukuhla, ngokuqhelekileyo nge-1% ukuya kwi-10% ngonyaka.Xa imveliso iphela, kusekho izixa ezikhulu ze-oyile negesi eseleyo emhlabeni.Ukuphucula ukubuyiswa, iinkampani zeoli kunye negesi zisebenzisa iindlela zokubuyisela ezongezelelweyo.Amasimi e-oyile anokufikelela kumazinga okubuyisela phakathi kwe-5% kunye ne-50%, kwaye kumasimi avelisa kuphela igesi yendalo, eli zinga lingaphezulu (60% ukuya kuma-80%).
Isigaba sezothutho
Esi sigaba sibandakanya iinkqubo zokwahlula, ukucocwa, ukugcinwa kunye nokuthuthwa kwe-oyile ekrwada.I-oyile ekrwada idla ngokuthuthwa iye kwimizi-mveliso yokulungiswa kwemibhobho, iinqanawa okanye ezinye iindlela zothutho, apho iphathwa kwaye ilungiswe ngokufanelekileyo kwaye ekugqibeleni inikezelwe kwimarike.
Ukubaluleka kweimibhobho yaselwandlekwinkqubo yemigodi yeoli ayinakungahoywa.Bangakwazi ukuthutha ngokufanelekileyo i-oyile ekrwada phakathi kwezixhobo ezingaselunxwemeni (amaqonga, indawo enye, njl.njl.) kunye ne-PLEM ephantsi kolwandle okanye ii-tankers, ukuphucula ukusebenza kakuhle kokuthuthwa kwe-oyile ekrwada kunye nokuqinisekisa ukhuseleko kunye nokukhuselwa kwendalo.
Ukupheliswa kunye nokulahlwa
Xa izibonelelo zomthombo we-oyile zichithwa ngokuthe ngcembe okanye umjikelezo wophuhliso uphela, ukuchithwa kunye nokulahlwa komthombo weoli kuya kufuneka.Esi sigaba siquka ukudilizwa kunye nokucoca iindawo zokomba, ukulahlwa kwenkunkuma, kunye nokubuyiselwa kokusingqongileyo.Ngexesha lale nkqubo, imithetho nemigaqo yokusingqongileyo kufuneka iqwalaselwe ngokungqongqo ukuqinisekisa ukuba inkqubo yenkunkuma ayinayo impembelelo embi kokusingqongileyo.
