Abstract
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.
Claims19
A method comprising:
- 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,
- wherein the converter material comprises at least one of:
- tungsten, rhenium, osmium, platinum, thorium, uranium, neptunium, lead, mercury, thallium, gold, iridium, iron, aluminum, tin, and any combination thereof;
- and
- irradiating the settable composition with the bremsstrahlung photons.
A method comprising:
- providing a settable hydraulic cement 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 hydraulic cement composition;
- producing a pulsed electron beam in the electron accelerator tool with a trajectory that impinges a converter material, thereby converting the pulsed electron beam to bremsstrahlung photons, wherein the pulsed electron beam has an average current of about 10 microamps to about 10 milliamps;
- and
- irradiating the settable hydraulic cement composition with the bremsstrahlung photons.
A method comprising:
- 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 that is a portion of a housing of the electron accelerator tool, thereby converting the electron beam to bremsstrahlung photons, wherein the electron beam has an average current of about 10 microamps to about 10 milliamps;
- and
- wherein the converter material comprises at least one of:
- tungsten, rhenium, osmium, platinum, thorium, uranium, neptunium, lead, mercury, thallium, gold, iridium, iron, aluminum, tin, and any combination thereof;
- and
- irradiating the settable composition with the bremsstrahlung photons.
