Abstract

En innkapslet brytekjemikalieblanding for anvendelse ved en fraktureringsprosess i en olje- eller gass-stimu- leringsoperasjon omfatter: (a) et brytekjemikalium, (b) et vannopploselig forseglende lag, såsom urea, med en tykkelse i området 1-30 pm, avsatt på overflaten av brytekjemikaliet og som innkapsler dette, og (c) et pinhole-fritt belegg av en noytralisert sulfonert elastomer polymer i en tykkelse på 2-80 pm, avsatt på overflaten av det belagte brytekjemikalium, hvilken nøytralisert sulfonert polymer innkapsler brytekjerci- kaliet og er permeabelt for tarytekjemikaliet.
