Abstract

Fremgangsmåte for å redusere avsetning av avleiringer i et brønnhull som det utvinnes en vandig fase fra, og i en omgivende formasjon som omfatter CaSO4, omfattende trinnene: a) tilveiebringelse av en oppløsning omfattende en anionisk avleiringsinhibitor og et salt med et énverdig kation i en konsentrasjon som er effektiv til minst å fordoble opp- løseligheten av kalsiumsulfat sammenlig- net med en avleiringsinhibitor-oppløs- ning i fravær av saltet med énverdig kation; b) innsprøytning av oppløsningen i formasjonen; c j utfelling av en del av den anioniske avleiringsinhibitor i for- masjonen i form av et kalsiumsalt av denne; og d) utvinning av den vandige fase fra brønnhullet. Det beskrives også en vandig oppløsning av avleiringsinhibitoren omfattende en organofosforholdig avleiringsinhibitor og et salt omfattende et énverdig kation.
