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.
Claims9
A method for treating a subterranean formation, comprising:
- using a downhole characterization tool to perform a downhole logging or imaging operation to measure the sizes of fractures, wormholes and perforations in the subterranean formation;
- using the results of the logging or imaging operation to determine an optimal size of particles for plugging the fractures, wormholes and perforations
- choosing a three-dimensional particle shape of the particles to reduce permeability of a plug of the particles, wherein the particles comprise a rigid core with a component attached to the rigid core, the components selected from the group consisting of a fiber, a film, and a flake, wherein the rigid core is a sphere, and the plug permeability is at least 56% lower than a second plug consisting of spheres having a size substantially equal to that of the particles;
- and
- introducing into a subterranean formation, a treatment fluid comprising the particles forming a plug in the subterranean formation.
