Scleroglucan gel applied to the oil industry |
摘要 |
The permeability of a subterranean reservoir can be more easily controlled by first injecting a crosslinking agent solution and then subsequently injecting a scleroglucan solution to thereby form, in situ, crosslinked scleroglucan gel. This reverse order of injection allows for a more homogeneous gel propagation without substantial risk of plugging.
