Ukadaulo wobwezeretsa mafuta umatanthauza luso lotulutsa mafuta m'minda yamafuta. Kusintha kwa ukadaulo uwu ndikofunikira kwambiri pakukula kwa makampani opanga mafuta. Pakapita nthawi, ukadaulo wobwezeretsa mafuta wapita patsogolo kwambiri zomwe sizinangowonjezera luso lamafutakuchotsedwa kwa nthaka koma kunakhudzanso kwambiri chilengedwe, chuma, ndi mfundo za mphamvu.
Pankhani yopanga mafuta a hydrocarbon, kubwezeretsa mafuta ndi njira yofunika kwambiri yomwe cholinga chake ndi kutulutsa mafuta ndi mpweya wochuluka momwe zingathere kuchokera m'malo osungira mafuta okhala ndi mafuta a hydrocarbon ambiri. Pamene moyo wa chitsime cha mafuta ukupita patsogolo,aChiŵerengero cha kupanga chimasintha. Pofuna kusunga ndi kukulitsa mphamvu ya kupanga ya chitsime, nthawi zambiri pamafunika kukulitsa kapangidwe kake. Kutengera ndi zaka za chitsime,amakhalidwe a kapangidwe ndiaNdalama zogwirira ntchito, ukadaulo ndi njira zosiyanasiyana zimagwiritsidwa ntchito pazigawo zosiyanasiyana. Pali magulu atatu akuluakulu a ukadaulo wobwezeretsa mafuta: kubwezeretsa mafuta koyambirira, kubwezeretsa mafuta kwachiwiri, ndi kubwezeretsa mafuta kwachitatu (komwe kumadziwikanso kuti kubwezeretsa mafuta kowonjezereka, EOR).
Kubwezeretsa mafuta koyamba kumadalira kwambiri mphamvu ya thankiyo kuti iyendetse mafuta ku chitsime. Pamene mphamvu ya thankiyo yatsika ndipo singathe kusunga kuchuluka kokwanira kopangira, kubwezeretsa mafuta kwachiwiri nthawi zambiri kumayamba. Gawoli makamaka limaphatikizapo kukweza mphamvu ya thankiyo kudzera mu jakisoni wa madzi kapena gasi, motero kupitiriza kukankhira mafuta ku chitsimecho. Kubwezeretsa mafuta kwapamwamba, kapena kubwezeretsanso mafuta kwabwino, ndi ukadaulo wovuta kwambiri womwe umaphatikizapo kugwiritsa ntchito mankhwala, kutentha kapena kulowetsa gasi kuti mafuta awonjezere kubwezeretsanso. Ukadaulo uwu ukhoza kusuntha bwino mafuta otsala omwe ali mu thankiyo, ndikuwonjezera kwambiri mphamvu ya kubwezeretsanso mafuta.
● Kulowetsa mpweya: Kulowetsa mpweya m'malo osungira mafuta kuti musinthe mphamvu ndi madzi a m'malo osungira mafuta, motero kumalimbikitsa kuyenda ndi kupanga mafuta osakonzedwa.
● Kuthira mafuta odzola: Kumatchedwanso kuti kuchira mafuta odzola, kumatenthetsa malo osungira mafuta pothira mafuta odzola otentha kwambiri kuti mafutawo asavutike kuyenda bwino, zomwe zimapangitsa kuti mafutawo aziyenda mosavuta. Ndikoyenera kwambiri malo osungira mafuta odzola mafuta odzola kwambiri kapena olemera.
● Kulowetsa mankhwala: Mwa kulowetsa mankhwala (monga ma surfactants, ma polima ndi ma alkali), mphamvu zakuthupi ndi zamakemikolo za mafuta osakonzedwa zimatha kusinthidwa, motero kukweza kusinthasintha kwa mafuta osakonzedwa, kuchepetsa kupsinjika kwa nkhope ndikuwongolera magwiridwe antchito obwezeretsa.
● CO2jakisoni: Iyi ndi njira yapadera yojambulira mpweya yomwe, pojambulira kaboni dioksidayo, singangochepetsa kukhuthala kwa mafuta, komanso imathandizira kuchira mwa kuwonjezera kuthamanga kwa madzi m'malo osungiramo mafuta ndikuchepetsa kuchuluka kwa mafuta osaphika otsala. Kuphatikiza apo, njira iyi ilinso ndi ubwino wina pazachilengedwe chifukwa cha CO22akhoza kusungidwa pansi pa nthaka.
● Ukadaulo wa Plasma Pulse: Uwu ndi ukadaulo watsopano womwe umapanga ma plasma pulse amphamvu kwambiri kuti alimbikitse dziwe, kupanga ma fractures, kuwonjezera kulowetsedwa kwa madzi, motero kuwonjezera kuyenda kwa mafuta osakonzedwa. Ngakhale ukadaulo uwu ukadali mu gawo loyesera, ukuwonetsa kuthekera kokonzanso bwino mitundu ina ya dziwe.
Ukadaulo uliwonse wa EOR uli ndi mikhalidwe yakeyake yogwirira ntchito komanso kusanthula mtengo ndi phindu, ndipo nthawi zambiri ndikofunikira kusankha njira yoyenera kwambiri kutengera momwe malo osungiramo mafuta alili, momwe mafuta osakonzedwa bwino alili komanso zinthu zachuma. Kugwiritsa ntchito ukadaulo wa EOR kungathandize kwambiri pazachuma cha malo osungiramo mafuta ndikuwonjezera nthawi yopangira mafuta, zomwe ndizofunikira kwambiri pakukula kokhazikika kwa zinthu zamafuta padziko lonse lapansi.
