Abstract (en)
A method of induced fracturing of a subsurface formation(10) comprises sequentially injecting at least partly liquefied inert fluid slugs through an array of injection wells (1-6, 11-20) into different parts of the formation(10) such that the formation initially freezes and contracts and subsequently expands due to the evaporation of the inert fluid, thereby enhancing the induced fracturing process.
