I-Vaalco Energy Ithola Ubuholi Benkundla YaseKossipo e-Ivory Coast Ukuthuthukisa Ukuthuthukiswa Kawoyela Negesi e-Afrika

Inkampani yamandla ase-U.S. i-Valco Energy ithenge isabelo esingu-60% esisebenzayo emkhakheni ongaphansi kwamanzi i-Kossipo e-Ivory Coast, kanti inkampani kawoyela kazwelonke i-PetroCI iphethe esinye isabelo esingu-40%. Lesi sivumelwano sibonisa intuthuko ebalulekile ye-Valco ekuthuthukisweni kukagwayi kanye negesi kulo lonke elase-Afrika.

Iphuli le-Kossipo litholakele ngo-2002, likhona ebhlockini le-CI-40, futhi lihlolwe ngo-2019. Izinsiza ezilinganisiwe ze-2C zalesi sikhala zilinganiselwa cishe kumamitha angama-102 million we-barrels we-oyili elilingana, kufaka phakathi cishe ama-barrels angama-293 million wezinsiza ze-oyili elingcwele eningizimu-ntshonalanga kwephuli le-Baobab. Ukuhlolwa ngo-2019 kukhombisile ukuthi umthombo we-Kossipo-2A ukhiphe ngaphezu kwama-barrels angama-7,000 we-oyili elingcwele ngosuku. I-Vaalco ihlela ukuqeda uhlelo lokuthuthukiswa kwesikhala engxenyeni yesibili ka-2026 futhi isebenzise idatha entsha ye-seismic ye-subsea ukuze ithuthukise isu lokuthuthukiswa.

Ngaleso sikhathi, iVaalco iphinde yathuthuka emisebenzini yayo ye-oyili negesi eGabon. Le nkampani iqedile ukuhlinzwa nokwethulwa komthombo wokuthuthukiswa kwe-Etame 15H-ST ebhuthini le-1V le-Etame. Umthombo unendawo yokukhokha engama-250 amamitha ku-Gamba sandstone futhi ufinyelele umjikelezo ozinzile ophakathi kuka-2,000 amabhali ngosuku usebenzisa ipompo ye-submersible kagesi, enokuphuma kwamanzi okungu-38%, okuhambisana nezibikezelo. Ngaphezu kwalokho, umthombo wokuhlola eWest Etame uqale ukusebenza maphakathi noFebhuwari futhi kulindeleke ukuthi ufinyelele umgomo maphakathi noMashi. Imiphumela ingakhuphula ukukhiqizwa nezinsiza ngempela ekupheleni kuka-2026.

U-CEO we-Vaalco uGeorge Maxwell uthe, "Siqala u-2026 ngezikhathi ezibalulekile ezibeka i-Vaalco endaweni yokufeza ukukhula kwemikhiqizo okukhuluma ngakho okungu-225% okwenziwe ngokuqhubekayo ngo-2030. Siqinisekisiwe njengomphakathi ophatha insimu ye-Kossipo, enentshisekelo yokusebenza engu-60% kulolu tholakala, olunama-barrels angama-293 million e-oyili alinganiselwa ezinqolobaneni, atholakala eningizimu-ntshonalanga kwensimu yethu ye-Baobab enezithelo eziningi ebhlockini le-CI-40." Wengezelela, "Sisebenza ngokubambisana nomlingani wethu uPetroCI ukuze sithumele i-FDP engxenyeni yesibili ka-2026, esikholwa ukuthi izosiza i-Vaalco ukukhulisa ukukhiqiza e-Côte d'Ivoire. Sijabule futhi ngokuqala okuhle komkhankaso wethu wokubhoboza e-Gabon, lapho i-ET-15H-ST ibhalisela ukuhamba kwama-barrels angama-2,000 ngosuku."

NgoMashi 2025, iVaalco iphinde yathola u-70% wentshisekelo ku-block ye-CI-705 e-Tano Basin yaseCôte d'Ivoire futhi izosebenza ngokubambisana neCôte d'Ivoire Exploration Petroleum Company kanye nePetroCI. Lezi zinhlelo zikhombisa imizamo esebenzayo yeVaalco yokwandisa imisebenzi yayo yokukhiqiza uwoyela nogesi e-Afrika nokuthuthukisa ukuthuthukiswa kwezimboni ezifana ne-Kossipo field.

Ukukhishwa kowoyela nogesi yemvelo akukwazi ukufezeka ngaphandle kokusebenzisa ama-desanders.

Shanghai SAGA Offshore Engineering Co., Ltd., yasungulwa eShanghai ngo-2016, iyinkampani yezobuchwepheshe yesimanje ehlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nezinsizakalo. Sigxile ekuthuthukiseni imishini yokuhlukanisa nokuhlunga emikhakheni kawoyela, igesi, kanye ne-petrochemical. Iphothifoliyo yethu yemikhiqizo ephezulu yokusebenza ifaka phakathi ama-hydrocyclones okukhishwa kawoyela/amanzi, ama-desanders ezinsalela ezincane, kanye nezinsiza zokuhlanza ezihlanganisiwe. Sinikeza izixazululo eziphelele ezibekwe phezulu futhi siphinde sinikeze ukulungiswa kwemishini yeqembu lesithathu kanye nezinsizakalo zokuthengisa ngemva kokuthengisa. Siphatha amalungelo obunikazi amaningi futhi sisebenza ngaphansi kwesistimu yokuphatha ye-DNV-GL eqinisekisiwe ye-ISO-9001, ISO-14001, kanye ne-ISO-45001, sithumela izixazululo ezithuthukisiwe zezinqubo, ukuklama kwemikhiqizo okunembile, ukuhambisana okuqinile nezincazelo zobunjiniyela, kanye nokwesekwa okuqhubekayo kokusebenza.

Okwethu ama-desanders e-cyclone anekhono eliphezulu, edumelekile ngenxa yokuhlukaniswa kwabo okukhulu okungu-98%, bathole ukuqashelwa kubaholi bamandla bamazwe omhlaba. Bakhiwe ngama-ceramics aphumelelayo anokugqoka, lezi zinsiza zifeza ukususa u-98% wezinsalela ezincane njenge-0.5 microns emoyeni. Le msebenzi ivumela ukujolisa kabusha igesi ekhiqiziwe ukuze kube nokufaka okuxubile ezindaweni ezinamathuba aphansi, isixazululo esibalulekile sokuthuthukisa ukuvuselelwa kwefutha ezindaweni ezinzima. Ngakolunye uhlangothi, zingaphatha amanzi akhiqiziwe, zisuse u-98% wezinsalela ezinkulu kune-2 microns ukuze zibuyele ngqo, ngaleyo ndlela zandisa ukusebenza kahle kokufaka amanzi ngenkathi kuncishiswa umthelela wemvelo.

Umkhiqizo wethu omusha—I-Desander Ephumelela Kakhulu Yamaphakethe Amancane Kakhuluiyidivayisi yokuhlukanisa uketshezi-okuqinile esebenzisa umgomo ophumelelayo we-centrifugal ukuhlukanisa izinto ezingcolile ezintantayo—njengezinto eziqinile emanzini akhiqiziwe, amanzi olwandle, i-condensate, amaphakethe amancane eketshezini elinamandla aphezulu, kanye nomgubo we-catalyst kuma-reactor—kusuka eketshezini (uketshezi, igesi, noma ingxube yoketshezi negesi). Iyakwazi ukususa kahle amaphakethe aqinile osayizi abafika ku-2 microns (ngokuphumelela okungu-98%) noma amancane.

I-Desander Ephumelela Kakhulu Yamaphakethe Amancane Kakhuluihlinzeka ngokuphumelela okuphezulu ekususweni kwesihlabathi, ikwazi ukususa amaphakethe aqinile afika ku-2 microns. Le mishini inendawo encane, ayidingi amandla angaphandle noma izithako zamakhemikhali, futhi inomjikelezo wokuphila cishe weminyaka engu-20. Inikeza ikhono lokukhipha isihlabathi ku-inthanethi ngaphandle kwesidingo sokuyeka ukukhiqiza.

Kufakazelwe emikhakheni emikhulu yomhlaba ephethwe yi-CNOOC, CNPC, Petronas, nabanye kulo lonke elaseNingizimu-mpumalanga ye-Asia, ama-SAGA desanders afakwa kumapulatifomu ezingosi zomthombo kanye nawokukhiqiza. Ahlinzeka ngokususwa okuthembekile kwezinto eziqinile egazini, uketshezi lomthombo, kanye ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ekuvikelweni komjikelezo wokukhiqiza, kanye nezinhlelo zokujova/ukugcwalisa amanzi.

Ngaphandle kwama-desanders, i-SAGA inikeza iqoqo lobuchwepheshe bokuhlukanisa obunconywayo. Umugqa womkhiqizo wethu uhlanganisa izinhlelo zamamembrane zokususa i-CO₂ yegesi yemvelo, ama-hydrocyclones okukhipha uwoyela, ama-flotation units (CFUs) anokusebenza okuphezulu futhi akhanyayo, ukususwa kwesihlabathi segesi ye-shale, Iphakethe lokukhipha amanzi le-Cyclonic elokwelapha amanzi akhiqiziwe, futhi ama-hydrocyclones anezimfihlo eziningi, ahlinzeka ngezixazululo eziphelele izinselelo eziqinile zemboni.
