Abstract
Official abstract text for this publication.
Of the many compositions and methods provided herein, an example method includes a method of treating a subterranean formation that comprises combining components comprising water and a density-matched suspension to prepare a treatment fluid, wherein the density-matched suspension comprises a suspending liquid and a solid particle suspended in the suspending liquid, and introducing the treatment fluid into a well bore. An example composition includes a suspension that comprises a suspending liquid comprising a hydrophobic liquid, wherein the hydrophobic liquid hydrolyzes when placed in contact with an aqueous fluid to form hydrophilic products, and a solid particle suspended in the suspending liquid, wherein the suspension is a density-matched suspension.
First claim
Opening claim text (preview).
What is claimed is: 1. A suspension comprising: a suspending liquid comprising a hydrophobic liquid, wherein the hydrophobic liquid hydrolyzes when placed in contact with an aqueous fluid to form one or more hydrophilic product; and a solid particle suspended in the suspending liquid, wherein the suspension is a density-matched suspension, wherein the suspension comprises two or more hydrophobic liquids, and wherein at least one of the hydrophobic liquids has a density higher th…
