I-GeoPark isayina inkontileka yeminyaka engu-25 yokuthuthukisa insimu yase-Bare eVenezuela

I-PDVSA, inkampani kaphethiloli kahulumeni waseVenezuela, kanye ne-GeoPark, basayine ngokusemthethweni iSivumelwano Sokubamba Iqhaza Ekukhiqizeni (CPP) seminyaka engama-25 seBare block. I-Bare itholakala e-Orinoco Heavy Oil Belt yaseVenezuela, futhi iyimpahla evuthiwe yamafutha asindayo esivele ikhiqiza. Ngaphansi kwemibandela yesivumelwano, i-GeoPark izosebenza njengomqhubi wephrojekthi, ithwale u-100% wezindleko zongqalasizinda ngaphansi kohlelo lokusebenza olugunyaziwe, futhi ibe ne-65% yenzuzo yokusebenza ephelele ephrojekthini. Isivumelwano siphinde sinikeze umqhubi amalungelo okuthengisa ngqo nokwenza imali ngemikhiqizo kawoyela negesi, ukusebenzisa ingqalasizinda ebalulekile, kanye nokubamba iqhaza ekulawuleni ukusebenza, phakathi kwamanye amalungelo.

I-Bare block igcina uwoyela ongakathintwa (OOIP) olinganiselwa kumamabherili ayizigidi eziyizinkulungwane ezingu-15.7, nomlando wokukhiqiza oqoqiwe udlula izigidi zamabherili ezingama-700, futhi kukhona imithombo ecishe ibe ngu-1,100 okwamanje. Ukuphakama komlando wokukhiqiza kwaleli block kudlule amabherili ayi-100,000 ngosuku, kanti umkhiqizo wamanje uwonke usukuma emabherilini acishe abe ngu-11,000 ngosuku. Uhlelo lokuphinda luthuthukise i-GeoPark luhlose ukuphakama komkhiqizo wonke olinganiselwa emabherilini angu-85,000 kuya ku-95,000 ngosuku, kanti umkhiqizo ohlobene ne-GeoPark kulindeleke ukuthi uqhubeke usezingeni eliphakeme lamabherili angu-55,000 kuya ku-62,000 ngosuku iminyaka engaphezu kweyishumi.

Uhlelo lwanamuhla lokuthuthukisa kulinganiselwa ukuthi luzoletha cishe izigidi ezingama-400 zamabhareli zokukhiqiza okuqoqiwe ku-GeoPark futhi luhlose ukukhuphula isilinganiso sokubuyiswa kwe-Bare block kusuka ku-4%–5% yamanje kuye ku-8%–9%. Lolu hlelo luzoqaliswa ngezigaba kusetshenziswa inethiwekhi yemithombo ekhona kanye nengqalasizinda esivele yakhiwe ukuze kuvuselelwe insimu, okuhlanganisa ukubuyisela nokuthuthukisa amandla okukhiqiza akhona, ukulungiswa kwengqalasizinda, kanye nokumba kwemithombo yokukhiqiza okulandelayo kanye nokutshalwa kwezimali kwezinsiza ezingaphezulu.

Iphrojekthi ye-Bare yaqhutshwa yi-Grupo Gilinski njengomhleli wokuthengiselana. I-GeoPark yaqala yathola inzalo engu-5% enkampanini ephethe amalungelo e-CPP, futhi kamuva ihlela ukuthola insalela engu-95% yenzalo ephethwe yi-Grupo Gilinski, ngamasheya ayizigidi ezingama-42.1 e-GeoPark njengendlela yokukhokha eyisisekelo. Intengo yokukhishwa kwamasheya ibekwe ku-$12.22 ngesheya ngalinye, okumelela inzuzo engaba ngu-26% ngaphezu kwesilinganiso esisindayo sevolumu sezinsuku ezingama-30 esingu-$9.67 ngesikhathi sokubhekwa; lolu hlelo lokuthengiselana luhambisana nenani elilinganiselwa ku-$160 million. Lapho kuqedwa, i-Grupo Gilinski kulindeleka ukuthi ibe ngumnikazi omkhulu we-GeoPark ngokungaqondile.

IGeoPark yembula ngoSepthemba 2 ukuthi ukusebenza kohlaka lwenkontileka yephrojekthi ye-Bare kusazoncika ekuvunyelweni okufanele, izigunyazo, ukucaciswa kwezomthetho, kanye nezidingo zokuthobela izinhlawulo, ngesilinganiso esiphezulu sesikhathi sokucubungula esingaba ngamalanga angu-120. Ngakho-ke, ukusayinwa okusemthethweni kwe-CPP ngoSepthemba 4 kumelela umgogodla omusha wenkontileka walo msebenzi, ngemva kwalokho inqubo izongena esigabeni sokuthola izimvume ezifanele kanye nokufeza izimo zokuqala ukusebenza kwenkontileka.

Ukukhishwa kukawoyela negesi yemvelo akunakwenzeka ngaphandle kwemishini yokuhlukanisa.

I-SHANGHAI SAGA Offshore Engineering Co., Ltd., eyasungulwa e-Shanghai ngo-2016, iyinkampani yesimanje yezobuchwepheshe ehlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nesevisi. Sizinikele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga yezimboni zikawoyela, igesi, kanye ne-petrochemical. Iqoqo lethu lemikhiqizo enempumelelo ephezulu lihlanganisa ama-hydrocyclone okukhipha uwoyela/okukhipha amanzi, ama-desander ezinhlayiyaneni zama-micron, kanye nama-compact flotation units. Sihlinzeka ngezixazululo eziphelele ezihlanganisiwe (skid-mounted) futhi sinikeza nezinsiza zokuguqula imishini yezinkampani zangaphandle kanye nesevisi yangemva kokuthengisa. Siphethe amalungelo amaningi obunikazi (patents) futhi sisebenza ngaphansi kohlelo lokuphatha olugunyazwe yi-DNV-GL lwe-ISO-9001, ISO-14001, kanye ne-ISO-45001, siletha izixazululo ezingcono kakhulu zezinqubo, ukuklama okunembile kwemikhiqizo, ukuhambisana ngokuqinile nezimfuneko zobunjiniyela, kanye nokusekelwa okuqhubekayo kokusebenza.

Ama-ama-cyclone desander asebenza kahle kakhulu, adume ukuthi bahlukanisa amazinga angu-98% abhekelelwe, bathole ukuqashelwa ngabaholi bamandla bamazwe ngamazwe. Yakhiwe ngezinto ezithuthukisiwe ezingqinamba ezingama-ceramics, lezi zingxenye zifeza ukususwa kwama-98% ezinhlayiyeni ezicwengekileyo ezingama-0.5 microns emifuleni yegesi. Lokhu kusebenza kuvumela ukufakwa kabusha kwegesi ekhiqiziwe ukuze kuhlanganiswe oketshezini olungena emithonjeni ephansi, okuyisixazululo esibalulekile sokuthuthukisa ukukhipha uwoyela ezindaweni ezinzima. Ngokunye, zingalapha amanzi akhiqiziwe, zisuse ama-98% ezinhlayiyeni ezinkulu kuno-2 microns ukuze ziphinde zifakwe ngqo, ngaleyo ndlela zithuthukise ukusebenza kokufaka amanzi kuyilapho zinciphisa umthelela emvelweni.

Umkhiqizo wethu omusha—I-Desander Yezinhlayiya Ezingcono Kakhulu Ezingatholakali iyithuluzi lokuhlukanisa uketshezi nokuqinile elisebenzisa umgomo we-centrifugal osebenzayo ukuhlukanisa ukungcola okumisiwe—njengezinto eziqinile emanzini akhiqizwayo, amanzi olwandle, i-condensate, izinhlayiya ezincane eketshezini olunamandla aphezulu, nempuphu ye-catalyst kuma-reactor—kuketshezi (uketshezi, amagesi, noma izingxube zegesi noketshezi). Isusa ngempumelelo izinhlayiya eziqinile ezifinyelela kuma-micron angu-2 (ngempumelelo engu-98%) noma ngaphansi.

I-Desander Yezinhlayiya Ezingcono Kakhulu Ezingatholakali iletha izinga eliphezulu lokususa isihlabathi, ikwazi ukususa izinhlayiya eziqinile ezifinyelela kuma-micron angu-2. Umshini unendawo encane, awudingi amandla angaphandle noma izithako zamakhemikhali, futhi unempilo yokusebenza ecishe ibe yiminyaka engu-20. Unikeza amandla okukhipha isihlabathi ngenkathi usebenza ngaphandle kwesidingo sokumisa ukukhiqiza.

Kufakazwe emikhakheni emikhulu yomhlaba wonke ephethwe yi-CNOOC, CNPC, Petronas, nabanye eNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA asetshenziswa ezinkundleni zomthombo kanye nezinkundla zokukhiqiza. Ahlinzeka ngokususwa kwemfucuza ethembekile kugesi, uketshezi lomthombo, kanye ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ukuvikelwa kokugeleza kokukhiqiza, kanye nezinhlelo zokujova amanzi/ukugcwaliswa kwamanzi.

Ngaphandle kwama-desander, i-SAGA inikeza uhlu lwezobuchwepheshe bokuhlukanisa oludumile. Umugqa wethu wemikhiqizo uhlanganisa amasisitimu e-membrane okususa i-CO₂ kugesi wemvelo, ama-deoiling hydrocyclone, amayunithi e-compact flotation (CFUs) asebenza kahle kakhulu, Ukususwa kwesihlabathi se-Shale gas, Iphakethe lokunciphisa amanzi nge-cyclonic nokwelashwa kwamanzi akhiqizwayo, futhi ama-hydrocyclone anamagumbi amaningi, enikeza izixazululo eziphelele ezinseleleni ezinzima kakhulu zemboni.
