Abstract
Et vannbasert borefluid, som har en polymerlateks som evner å tilveiebringe en omformbar lateksfilm på minst en del av en underjordisk formasjon, er funnet å kunne tilveiebringe redusert trykkinvasjon når det anvendes til å bore i leirskiferformasjoner ved hydrokarbon-utvinningsprosesser. Fortrinnsvis anvendes et fellingsmiddel, så som et silikat eller en aluminiumforbindelse (f.eks. natrium-aluminat) sammen med polymeren. Vannet som er tilstede inneholder typisk et salt, slik at det dannes en saltoppløsning, ofte til metningspunktet, men opp-finnelsen kan også anvendes med ferskvann. Dersom det anvendes salt, kan det ofte være nyttig å anvende et overflateaktivt stoff i tillegg, så som for eksempel betain.
