Catalog Well Integrity Technology
Crucial to restoring caprock integrity by sealing each well with a permanent, leak-free barrier.
D264 nanosealant is a single-component, self-diverting technology used to repair small cracks and microannuli in a cemented annulus. It is ideal for repairs for which injectivity is too low to pass Portland cement–based systems or microcement systems such as SqueezeCRETE remedial cementing solution.
Because D264 nanosealant is a single-component system, no mixing or blending is required at surface. Its low rheology and nanosized particles deliver injectivity similar to that of water. It has been demonstrated to penetrate leaks as small as 20 um.
An ideal example application would be to use D264 nanosealant to repair old cemented well sections prior to abandonment or after placing abandonment cement plugs that show signs of leakage.
