Ubufakazi bokuqhuma kwe-Shenhai
Izinhlobo ezahlukene zezinto zikagesi ezingaqhumi zidinga amazinga ahlukene okuvikela isikhwama. Lezi zindinganiso, eyaziwa ngokuthi amabanga okuvikela, isho ikhono le-casing lokuvimba izinto zangaphandle ukuthi zingangeni ngaphakathi kwayo futhi inikeze ukumelana nokungena kwamanzi.. Ngokusho kwe “Iziqu Zokuvikeleka Ezihlinzekwe Ngokubiyelwe (Ikhodi ye-IP)” (I-GB4208), Ibanga lokuvikela lebhokisi liboniswa ikhodi ye-IP. Le khodi iqukethe ama-initials e-IP (Ukuvikelwa Kwamazwe Ngamazwe), kulandelwa izinombolo ezimbili futhi ngezinye izikhathi izinhlamvu ezengeziwe ozikhethela zona (ezikhishwa ngezikhathi ezithile).
| Inombolo | Ibanga lokuvikela | Chaza |
|---|---|---|
| 0 | Akuvikelekile | Akukho ukuvikelwa okukhethekile emanzini noma kumswakama |
| 1 | Vimbela amaconsi amanzi ukuthi angangeni | Amaconsi amanzi ahla aqondile (njenge-condensate) ngeke idale umonakalo ezintweni ezisebenza ngogesi |
| 2 | Uma kutshekiswa ku 15 amadigri, amaconsi amanzi asengavinjelwa ukuthi angacwili | Lapho into esetshenziswayo itshekele phezulu ukuze 15 amadigri, ukuconsa amanzi ngeke kudale umonakalo kumshini |
| 3 | Vimbela amanzi afuthwe ukuthi angangeni | Vimbela imvula noma ukulimala kwezinto zikagesi ezibangelwa amanzi afafazwe eziqondisweni nge-engeli eqondile engaphansi 60 amadigri |
| 4 | Vimbela ukuchaphaza kwamanzi ukuthi angangeni | Vimbela ukuchaphaza kwamanzi kuzo zonke izinhlangothi ukuthi kungangeni ezintweni zikagesi futhi kudale umonakalo |
| 5 | Vimbela amanzi afuthwe ukuthi angangeni | Vimbela ukufafaza kwamanzi anengcindezi ephansi ehlala okungenani 3 imizuzu |
| 6 | Vimbela amagagasi amakhulu ukuthi angangeni | Vimbela ukufafaza kwamanzi ngokweqile okuhlala okungenani 3 imizuzu |
| 7 | Vimbela ukucwiliswa emanzini ngesikhathi sokucwiliswa | Vimbela ukucwiliswa kwemiphumela ye 30 imizuzu emanzini kuze kufike 1 imitha ukujula |
| 8 | Vimbela ukucwiliswa emanzini ngesikhathi sokucwila | Vimbela imiphumela eqhubekayo yokucwiliswa emanzini ngokujula okwedlulele 1 imitha. Izimo ezinembile zicaciswa umenzi wedivayisi ngayinye. |
Inombolo yokuqala ikhombisa izinga lokuvikelwa ezintweni eziqinile, kuyilapho inombolo yesibili imelela izinga lokumelana namanzi. Ukuvikeleka ezintweni eziqinile kuyahluka 6 amazinga: izinga 0 akusho ukuvikeleka, kanye nezinga 6 kukhombisa ukuqina okuphelele kothuli, ngokuvikelwa okwandayo kancane kancane kusuka 0 ku 6. Ngokufanayo, izikhala zokuvikela amanzi 8 amazinga: izinga 0 akusho ukuvikeleka, kanye nezinga 8 kukhombisa ukufaneleka kokucwiliswa emanzini isikhathi eside, ngokuvikelwa okwandayo kancane kancane kusuka 0 ku 8.
