Abstract

Væsketapsregulerende additiv til anvendelse i oljebaserte bore-hullsvæsker inneholdende et løseliggjort lignittderivat og en oljesvellbar eller oljeløselig polymer. Det løseliggjorte lignittderivatet kan være oljeløseliggjort (f.eks. et lignitt/ aminkompleks) eller et vannløseliggjort (f.eks. kaustisert lignitt) og kan innarbeides i en polymer->matriks eller til-settes en polymer-løsning eller dispersjon i et løsningsmiddel-system.
