Abstract

Methods of treating a subterranean formation are disclosed that include introducing a treatment fluid including shaped particle and/or shaped uniform particles into a subterranean formation via a wellbore, and creating a plug including the shaped particle and/or shaped uniform particles of the treatment fluid.

Claims

1. A method for treating a subterranean formation comprising:

introducing a treatment fluid into a subterranean formation, the treatment fluid comprising a plurality of first particles, where

each particle of the plurality of first particles has a first three-dimensional shape, and

the dimensions of the first three-dimensional shape of each particle of the plurality of first particles are substantially uniform; and

forming a plug comprising at least a portion of the plurality of first particles in the subterranean formation;

wherein

the first three-dimensional shape is a member selected from the group consisting of a cylinder, a spherocylinder, and a polyhedral shape.

2. The method of claim 1, wherein the first three-dimensional shape comprises one or more flat faces.

3. The method of any preceding claim, wherein the first three-dimensional shape is a member selected from the group consisting of Platonic solids and Archimedean solids.

4. The method of any preceding claim, wherein the first three-dimensional shape is a tetrahedron.

5. The method of any preceding claim, wherein the plug is formed in one or more of a perforation, a fracture, or a wellbore in the subterranean formation.

6. The method of any preceding claim, wherein the plurality of first particles are composed of one or more material selected from the group consisting of degradable materials, chemically removable materials, dissolvable materials, meltable materials and non-removable materials.

8. The method of any preceding claim, wherein the dimensions of the first three-dimensional shape are determined based on measurements acquired with a downhole characterization tool.

9. The method of any preceding claim, wherein at least a portion of the plurality of first particles are made from a degradable material.

10. The method of any preceding claim, wherein the treatment fluid further comprises one or more additives selected from the group consisting of proppants, fibers, flakes and particulate materials.

11. The method of any preceding claim, further comprising degrading the plurality of first particles to remove the plug and increase the permeability of the subterranean formation, wherein the degradation of the plurality of first particles is triggered by a solvent, a temperature change, by a chemical reaction between the plurality of first particles and another reactant, or by a combination thereof.

12. The method of any preceding claim, wherein the treatment fluid further comprises a composite material having a rigid core.

13. The method of claim 12, wherein the composite material having a rigid core further comprises one or more films or fibers fixed to a surface of the rigid core.

14. The method of any preceding claim, wherein the treatment fluid further comprises a plurality of second particles, where each particle of the plurality of second particles has a second three-dimensional shape.

15. The method of claim 14, wherein the first three-dimensional shape includes one or more male connectors, and the second three-dimensional shape includes one or more female connectors, where each female connector is capable of engaging a male connector of the first three-dimensional shape.

7. A method of treating a subterranean formation comprising:

manufacturing a plurality of first particles at the well site via an apparatus for a building a three dimensional object, the apparatus comprising;

a storage chamber for storing build material; and

a metering system to regulate the quantity of build material delivered from the storage chamber to an operating position;

introducing a treatment fluid into a subterranean formation, the treatment fluid comprising the plurality of first particles, where

each particle of the plurality of first particles has a first three-dimensional shape, and

the dimensions of the first three-dimensional shape of each particle of the plurality of first particles are substantially uniform; and

forming a plug comprising at least a portion of the plurality of first particles in the subterranean formation;

wherein

the first three-dimensional shape is a member selected from the group consisting of a cylinder, a spherocylinder, and a polyhedral shape.
