Iikhemikhali ze-oyile ziimveliso zeekhemikhali ezisetyenziswa ekuphononongeni, ekukhupheni nasekulungiseni i-petroleum. Ziquka ulwelo lokugrumba, iikhemikhali zokuvelisa, iikhemikhali zokubuyisela i-oyile eziphuculweyo, njl.njl.
Eyokuqala lulwelo lokugrumba, oluquka udaka lokugrumba, udaka olunegwebu, udaka oluxineneyo, njl.njl., olusetyenziswa kwinkqubo yokujikeleza kodaka ngexesha lomsebenzi wokugrumba ukuthambisa nokupholisa, ukuphakamisa iziqwenga, kunye nokulinganisela uxinzelelo lomngxuma. Eyesibini kukuveliswa kweekhemikhali, ezinjengezigcina-mhlwa, izithinteli zokugrumba, izixubisi, njl.njl., ezisetyenziselwa ukugcina nokukhusela izixhobo ezifana nezixhobo zokugrumba, imibhobho kunye neetanki zokugcina igesi.
Iikhemikhali zikwadlala indima ebalulekileyo ekuphuculeni ukubuyiswa kweoyile, njengee-agents ezisusa ioyile yepolymer, ii-surfactants, njl.njl., ezinceda ekuphuculeni ukubuyiswa kweoyile ekrwada. Ngamafutshane, kukho iintlobo ezininzi zeekhemikhali ze-oyile, ezidlala indima ebalulekileyo kuzo zonke iinkalo zoshishino lwepetroleum kwaye zibonelela ngenkxaso ephambili ekuhlolweni nasekuvelisweni kwepetroleum.
