Abstract

Fremgangsmåte for oppbryting av filterkake i en undergrunnsformasjon, hvilken fremgangsmåte omfatter å: (i) innlemme i et behandlingsfluid en faststoffpolymer i stand til å bli omdannet ved hydrolyse til en eller flere organiske syrer; (ii) tilføre behandlingsfluidet inn i undergrunnsformasjonen; og (iii) tillate faststoffpolymeren å hydrolysere i nærvær av vann for å fremstille organisk syre slik at syreløselig materiale innenfor filterkaken eller tilgrensende formasjon oppløses.
