Abstract
A downhole tool or component thereof comprising a cellulosic derivative, wherein the cellulosic derivative is capable of at least partially degrading in a wellbore environment, thereby at least partially degrading the downhole tool or component thereof. Methods of introducing the downhole tool into a wellbore environment, performing a downhole operation, and at least partially degrading the downhole tool or component therein in the wellbore.
Claims21
A downhole tool or component thereof comprising a cellulosic derivative,
- wherein the cellulosic derivative is capable of at least partially degrading in a wellbore environment, thereby at least partially degrading the downhole tool or component thereof.
A method comprising:
- providing a downhole tool, wherein the downhole tool or a component thereof comprises a cellulosic derivative, and
- wherein the cellulosic derivative is capable of at least partially degrading in a wellbore environment, thereby at least partially degrading the downhole tool or component thereof;
- introducing the downhole tool into the wellbore;
