Abstract

Fremgangsmåte for å produsere en selvoppsplittende filterkake i en undergrunnsformasjon, hvilken fremgangsmåte omfatter: (a) innlemme inn i et borefluid en fast polymer i stand til å omdannes ved hydro- lyse til en eller flere organiske syrer; (b) anvende borefluidet for å bore et brønnhull inn i undergrunnsformasjonen slik at den faste polymeren i borefluidet bidrar til dannelsen av en filterkake; og (c) tillate den faste polymeren å hydrolysere i nærvær av vann og splitte integri- teten til filterkaken. Borefluid som inneholder som et brobyggende middel, en eller flere faste polymerer i stand til å omdannes ved hydrolyse til en eller flere organiske syrer, er også tilveiebrakt.
