The present invention relates to a mixture of various shapes of a dissolvable diverter material. Generally, the shapes range from a flake having a very high surface area to mass ratio the beads having a low surface area to mass ratio. However, the density of the various shapes may be manipulated by including voids or low-density materials within the shape. The density manipulation is desirable in order to match the transport properties of the various shapes to the transport fluid so that both shapes may arrive at the desired location at the desired time.

An infiltratable material forms a net shape containing a porous network that can be infiltrated with a supplemental material, commonly referred to as an infiltrant, e.g., by heating the infiltrant so that it melts and wicks into the porous network of the net shape. By using additive fabrication technologies to spatially dispose an infiltrant about an infiltratable structure, a composite structure can be created that advantageously controls the amount of infiltrant applied to the infiltratable structure and the spatial distribution of the infiltrant about and/or within the infiltratable structure prior to infiltration.

A cement composition for use in a well that penetrates a subterranean formation comprising: cement; and water, wherein the water is in a concentration in the range of about 220% to about 800% by weight of the cement, wherein the cement composition is acid soluble. A method of treating a subterranean formation comprising: introducing the cement composition into the subterranean formation; allowing the composition to set; and contacting the set cement composition with an acid.

A method can include conveying a dispensing tool through a wellbore, the dispensing tool including an enclosure containing plugging devices, and then opening the enclosure by cutting a material of the enclosure, thereby releasing the plugging devices from the enclosure into the wellbore at a downhole location. A dispensing tool can include a container having an enclosure therein, the enclosure including a flexible material that contains the plugging devices, and an end of the enclosure being secured to a member displaceable by an actuator. The enclosure material is cut in response to displacement of the member by the actuator. A plugging device can include at least one body configured to engage an opening in the well and block fluid flow through the opening, and multiple fibers including staple fibers or filaments formed into yarn.
