High Efficiency Radiation-Induced Triggering for Set-on-Command Compositions and Methods of Use

Baldasaro, N. G., Gupta, V., & Lewis, S. J. (2017). High Efficiency Radiation-Induced Triggering for Set-on-Command Compositions and Methods of Use (Patent No. 9,546,533.)

Systems and methods that utilize bremsstrahlung radiation may be used to facilitate the setting of a settable composition. For example, a method may include providing a settable composition in a portion of a wellbore penetrating a subterranean formation, a portion of the subterranean formation, or both; conveying an electron accelerator tool along the wellbore proximal to the settable composition; producing an electron beam in the electron accelerator tool with a trajectory that impinges a converter material, thereby converting the electron beam to bremsstrahlung photons; and irradiating the settable composition with the bremsstrahlung photons.
