Fiber surface finishing
Embodiments disclosed herein relate to a fluid for use in well treatment having a carrier fluid and a plurality of altered fiber particles having a plurality of defects on a surface of the fiber particles. The fluid may be used for a method of fracturing a subterranean formation. The method includes injecting a fracturing fluid into a wellbore through the subterranean formation, thereby creating a fracture network in the subterranean formation, the fracturing fluid comprising a proppant and a plurality of fibers having a plurality of defects on a surface of the fibers.
1. A method of well treatment, comprising:
a) injecting a slurry comprising a fibrous material, wherein the fibrous material is present in the slurry as a dispersed material, wherein the fibrous material has a plurality of defects on a surface of the fibrous material, wherein the plurality of defects are produced during manufacturing of the fibers, wherein the fibers are drawn and scratched before cutting;
b) allowing the fibrous material to form a plug in one or more than one of a perforation, a fracture, and a wellbore in a well penetrating formation; and
c) performing a downhole operation.
2. The method of claim 1 , further comprising allowing the fibrous material to at least partially degrade after a selected duration such that the plug disappears.
3. A method for fracturing a subterranean formation, the method comprising:
injecting a fracturing fluid into a wellbore through the subterranean formation, thereby creating a fracture network in the subterranean formation, the fracturing fluid comprising a proppant and a plurality of fibers having a plurality of defects on a surface of the fibers, wherein the plurality of defects ranges from about 10 defects/mm of fiber length to about 300 defects/mm of fiber length; and
allowing the fracture network to close after injecting the fracturing wherein the plurality of defects are produced during manufacturing of the fibers, wherein the fibers are drawn and scratched before cutting.
4. The method of claim 3 , further comprising: producing hydrocarbons from the subterranean formation into the wellbore through a proppant pack including the plurality of fibers.
5. A method for fracturing a subterranean formation, comprising:
injecting a fracturing fluid into a wellbore through the subterranean formation, thereby creating a fracture network in the subterranean formation, the fracturing fluid comprising a proppant and a plurality of fibers;
after pumping of the fracturing fluid has begun, adding a second fluid to the fracturing fluid to initiate formation of a plurality of defects on the surface of the fibers in situ, wherein the second fluid is an organic solvent; and
allowing the fracture to close after injecting the fracturing fluid.
6. The method of claim 5 , further comprising: producing hydrocarbons from the subterranean formation into the wellbore through a proppant pack including the plurality of fibers.
7. The method of claim 5 , wherein the organic solvent comprises acetone, ethyl acetate, butyl acetate, acetonitrile, benzene, toluene, glycol ether solvents, alcohols, dibasic esters or esters of fatty acids.
