Abstract: A blend including 50% to 95% reinforcing particles by weight, and 5% to 50% filler particles by weight, of the blend, wherein the reinforcing particles have mean particle size within 70% or less of the mean particle size of the filler particles is disclosed. Such blends can be used to prepare metal matrix composites that can be infiltrated with a binder to form harden composites that can be used for the manufacture of tools.

Abstract: A method of in-line inspection of integrity of a pipeline includes identifying a first prospective cluster related to at least a first feature of the pipeline and a second prospective cluster related to at least a second feature of the pipeline. The method includes calculating an effective area using Length Adaptive Pressure Assessment (LAPA) techniques. The effective area corresponds to a lower calculated burst pressure than surrounding areas of the pipeline. LAPA techniques are used to determine if the first prospective cluster interacts with the second prospective cluster. The method includes combining the first and the second prospective cluster when the effective area includes the first and the second prospective cluster to form a resultant cluster. The method further includes generating an indication of an attribute of the resultant cluster.

Abstract: Structural metal-matrix composites (MMC) comprising a foam matrix material infiltrated with a binder material, where the binder material binds the foam matrix material to a structural element of a tool, thereby enhancing three-dimensional reinforcement of the tool. In some instances, the structural element is a portion of a wellbore tool or a bit body, such that portions of such tools or bit bodies are composed of the structural MMC. The foam matrix material may be composed of a metallic foam, a ceramic foam, and any combination thereof.
