Abstract

En innkapslet brytekjemikalieblanding anvendt ved en fraktureringsprosess i olje- eller gass-stimulering- seringsoperasjoner omfatter et brytekjemikalium og et pinhole-fritt belegg av en nøytralisert sulfonert elastomer polymer i en tykkelse på 2-80 pm, avsatt på overflaten av brytekjemikaliet, hvorved den ncytrali- serte sulfonerte polymer innkapsler brytekjemikaliet og hvor den nøytraliserte sulfonerte polymer er permeabel for brytekjemikaliet og hvor den nøytraliserte sulfo- nerte polymer er ikke-reaktiv i forhold til bryte- kjemikaliet.An encapsulated fracture chemical composition used in a fracturing process in oil or gas stimulation operations comprises a fracture chemical and a pinhole-free coating of a neutralized sulfonated elastomeric polymer at a thickness of 2-80 µm, deposited on the surface of the fracture chemical, serified sulfonated polymer encapsulates the break chemical and where the neutralized sulfonated polymer is permeable to the break chemical and where the neutralized sulfonated polymer is non-reactive to the break chemical.
