Abstract

The present disclosure provides new and innovative lost circulation material that is fabricated from mechanically reducing wind turbine blades to fragments (e.g., fibers, particles, etc.). The lost circulation material includes fibrous materials from one or more wind turbine blades, such as fiberglass, carbon fiber, balsa wood, and resin. The lost circulation material can be used as an additive in drilling mud or cement to treat the problem of lost circulation. In this way, fabricating lost circulation material from wind turbine blades provides safe and permanent disposal of industrial byproducts.

Claims (21)

1 . A method comprising:

adding a lost circulation material to liquid drilling fluid or cement to thereby form a mixture, wherein the lost circulation material includes a plurality of fragments comprising:

fiberglass of one or more wind turbine blades;

resin of one or more wind turbine blades;

carbon fiber of one or more wind turbine blades; and

balsa wood of one or more wind turbine blades,

wherein at least some of the plurality of fragments have a transverse dimension within a range of 1 to 2000 microns, inclusive; and

introducing the mixture into a geological formation.

2 . The method of claim 1 , wherein the lost circulation material is added to the liquid drilling fluid or cement in a concentration of 3 to 100 pounds per barrel of oil, inclusive.

3 . The method of claim 1 , wherein the plurality of fragments are fibrous.

4 . The method of claim 1 , wherein the plurality of fragments are granular.

5 . A method comprising:

introducing into a geological formation a mixture that includes a lost circulation material and liquid drilling fluid or cement, wherein the lost circulation material includes a plurality of fragments comprising:

fiberglass of one or more wind turbine blades;

resin of one or more wind turbine blades;

carbon fiber of one or more wind turbine blades; and

balsa wood of one or more wind turbine blades,

wherein at least some of the plurality of fragments have a transverse dimension within a range of 1 to 2000 microns, inclusive.

6 . The method of claim 5 , wherein the lost circulation material was added to the liquid drilling fluid or cement in a concentration of 3 to 100 pounds per barrel of oil, inclusive.

7 . The method of claim 5 , wherein the plurality of fragments are fibrous.

8 . The method of claim 5 , wherein the plurality of fragments are granular.
