GEL AND METHOD TO DELAY FLOW. |
| abstract |
A gel-like composition comprising a first substance selected from the group consisting of polyvinyl alcohol, a copolymer of polyvinyl alcohol and mixtures thereof, an aldehyde allowing crosslinking with the first substance, and water. This gel-like composition is useful for filling cracks in porous substances and for retarding the flow of fluids in subterranean formations. For example, a method is provided for retarding the flow of fluids in high permeability channels of an oil reservoir. Such a method is particularly useful during flooding operations in order to increase the sweeping efficiency of the oil recovery process. As these gels exhibit very good high temperature stability, they can be used in tanks having an average in situ temperature of 80oC or more. |
