Abstract
Official abstract text for this publication.
A treatment fluid comprises: a metal oxide, wherein the metal oxide is capable of forming a chelate complex or coordination complex with a ligand, wherein the chelate complex or coordination complex has a setting time of less than 90 minutes at a temperature of 71° F. and a pressure of 1 atmosphere. A method of treating a portion of a subterranean formation comprises: introducing the treatment fluid into the subterranean formation; allowing or causing a chelate complex or coordination complex to form between the metal oxide and a ligand; and allowing or causing the chelate complex or coordination complex to set.
First claim
Opening claim text (preview).
What is claimed is: 1. A treatment fluid comprising: a fluid, wherein the fluid is selected from the group consisting of water or a hydrocarbon liquid; and a metal oxide, wherein the metal oxide forms a chelate complex or coordination complex with a ligand, wherein the metal oxide is in a concentration in the range of about 10% to about 98% by weight of the treatment fluid, and wherein the chelate complex or coordination complex has a setting time of less than 90 minutes at a te…
