Abstract
Embodiments of the present invention provide compositions and methods for lining a wellbore. In certain aspects, the compositions and methods comprise providing a fluid composition that is solidifiable or gellable on exposure to actinic radiation of a predetermined wavelength at the wall of open-hole wellbore and providing actinic radiation at the predetermined wavelength to solidify or gel the composition. The predetermined wavelength lies in a range from 100 nm to 1500 nm.
Claims20
A wellbore fluid comprising:
- a fluid;
- and
- a composition comprising:
- a pre-polymer, wherein the pre-polymer is selected from the group consisting of substituted C2-5 alkenyl and substituted epoxidyl;
- and
- a photoinitiator, wherein the photoinitiator is selected from cation photoinitiator or free radical photoinitiator;
- wherein upon exposure to actinic radiation of a predetermined wavelength in the range of 100 nm to 1500 nm, the composition solidifies or gels to become impermeable to fluids.
4 more elements
A composition comprising:
- a filtercake;
- and
- a solidifiable or gellable fluid, wherein the solidifiable or gellable fluid forms part of the filter cake, and wherein the solidifiable or gellable fluid comprises:
- a pre-polymer, wherein the pre-polymer is selected from the group consisting of substituted C2-5 alkenyl and substituted epoxidyl;
- and
- a photoinitiator, wherein the photoinitiator is selected from cation photoinitiator or free radical photoinitiator;
- wherein upon exposure to actinic radiation of a predetermined wavelength in the range of 100 nm to 1500 nm, the composition solidifies or gels to become impermeable to fluids.
