    摘要: Foamable epoxy-based zonal isolation sealing compositions are disclosed and methods for isolating zones in borehole of oil and gas wells using the compositions. The foam nature of the cured seals provide sufficient compressibility and resiliency to be used with expandable tubing without substantial loss in sealant integrity and in squeeze operations.
