Ikoranabuhanga ryo kugarura amavuta risobanura ubushobozi bwo gukura peteroli mu bicuruzwa bya peteroli. Iterambere ry'iri koranabuhanga ni ingenzi mu iterambere ry'inganda za peteroli. Uko igihe cyagiye gihita, ikoranabuhanga ryo kugarura peteroli ryagiye rigira udushya twinshi tutanoze gusa ubushobozi bwoamavutagucukura ariko kandi byagize ingaruka zikomeye ku bidukikije, ubukungu, na politiki y'ingufu.
Mu rwego rwo gukora hydrocarbon, kugarura peteroli ni inzira y'ingenzi, intego yayo ikaba ari ukuvana peteroli na gaze byinshi bishoboka mu bigega bikungahaye kuri hydrocarbon. Uko ubuzima bw'iriba rya peteroli bugenda butera imbere,iIgipimo cy'umusaruro gikunze guhinduka. Kugira ngo ubushobozi bw'umusaruro w'iriba bukomeze kandi bwongererwe, hakenewe kongera gukangura imiterere yaryo. Bitewe n'imyaka y'iriba,iimiterere y'imiterere n'iikiguzi cy'imikorere, ikoranabuhanga n'uburyo butandukanye bikoreshwa mu byiciro bitandukanye. Hari ibyiciro bitatu by'ingenzi by'ikoranabuhanga ryo kugarura amavuta: kugarura amavuta y'ibanze, kugarura amavuta y'inyongera, no kugarura amavuta y'inyongera (bizwi kandi nka kugarura amavuta y'inyongera, EOR).
Gusubiza amavuta mu buryo bw'ibanze ahanini bishingiye ku gitutu cy'ikigega kugira ngo gitere amavuta ku mutwe w'iriba. Iyo igitutu cy'ikigega kigabanutse kandi kidashobora gukomeza gukora neza, ubusanzwe gusubiza amavuta mu buryo bw'ibanze bitangira. Iki cyiciro gikubiyemo kongera igitutu cy'ikigega binyuze mu gutera amazi cyangwa gaze, bityo bigatuma amavuta akomeza gusunika ku mutwe w'iriba. Gusubiza amavuta mu buryo bw'ikirenga, cyangwa kongera gusohora amavuta, ni ikoranabuhanga rigoye cyane rikoresha imiti, ikoreshwa mu gutera ubushyuhe cyangwa gaze kugira ngo wongere uburyo bwo kongera gusohora amavuta. Iri koranabuhanga rishobora kwimura peteroli isigaye mu kigega neza, rigatuma umusaruro w'amavuta muri rusange urushaho kwiyongera.
● Gutera gazi: Gutera gazi mu kigega cy'amavuta kugira ngo bihindure umuvuduko n'imiterere y'amazi by'ikigega, bityo bigateza imbere urujya n'uruza rw'amavuta mabi.
● Gutera umwuka: Bizwi kandi nka thermal oil recovery, bishyushya ikigega binyuze mu gutera umwuka ushyushye cyane kugira ngo bigabanye ubushyuhe bw'amavuta, bityo byorohe gutemba. Bikwiriye cyane cyane ibigega bifite ubushyuhe bwinshi cyangwa ibigega biremereye bya peteroli.
● Gutera imiti: Mu gutera imiti (nk'ibinyabutabire, polymeri na alkali), imiterere y'amavuta asanzwe n'imiti irashobora guhinduka, bityo bigatuma amavuta asanzwe ahinduka neza, bikagabanya imbaraga zo hagati y'amaso no kunoza uburyo bwo kuyagarura.
● CO2inshinge: Ubu buryo bwihariye bwo gutera gaze, binyuze mu gutera gaze karubone, ntibushobora gusa kugabanya ubukana bw'amavuta, ahubwo bunatuma igipimo cyo kugaruka gikomeza kwiyongera binyuze mu kongera umuvuduko w'amazi mu kigega no kugabanya ubwinshi bw'amavuta asigaye. Byongeye kandi, ubu buryo bufite inyungu zimwe na zimwe ku bidukikije kuko CO22bishobora gufatirwa munsi y'ubutaka.
● Ikoranabuhanga rya Plasma Pulse: Iri ni ikoranabuhanga rishya ritanga ingufu nyinshi mu gukurura ikigega, rigatuma habaho kuvunika, rikongera ubushobozi bwo kwinjira mu mubiri, bityo rikongera urujya n'uruza rw'amavuta. Nubwo iri koranabuhanga rikiri mu cyiciro cy'igerageza, rigaragaza ko rishobora kunoza gukira mu bwoko runaka bw'ikigega.
Buri koranabuhanga rya EOR rifite imiterere yaryo yihariye ikoreshwa hamwe n'isesengura ry'inyungu n'ikiguzi, kandi ubusanzwe ni ngombwa guhitamo uburyo bukwiye cyane hashingiwe ku miterere y'ubutaka bw'ikigega runaka, imiterere ya peteroli isanzwe n'ibintu by'ubukungu. Gukoresha ikoranabuhanga rya EOR bishobora kunoza cyane inyungu z'ubukungu bw'ibikomoka kuri peteroli no kongera igihe cyo gukora ibikomoka kuri peteroli, ibi bikaba bifite akamaro kanini mu iterambere rirambye ry'umutungo wa peteroli ku isi.
