Lewis, S. J., Davis, J. L., Gupta, V., Ostraat, M., Myers, D. F., Lamvik, M., Dummer, A. K., Rao, V., Roberts, L. R., Badalamenti, A., & Hoertz, P. (2016). Radiation-induced triggering for set-on-command sealant compositions. (U.S. Patent No. 9296938).
Sealant compositions comprising: a wellbore treatment fluid; a set modifier; and, a polymeric component that inhibits release of the set modifier; wherein exposure to ionizing radiation causes degradation of the polymeric component resulting in release of the set modifier and an increase in the mechanical strength of the sealant composition.
