Abstract
Official abstract text for this publication.
Methods including the steps of providing an injection well having unconsolidated particulates in one or more formation intervals along the wellbore that accept injection fluid; providing a consolidating treatment fluid comprising a base fluid and a consolidating agent; introducing the consolidating treatment fluid through the injection well, while the well is under injection, such that the consolidating treatment fluid enters into a portion of a formation interval along the wellbore that accepts injection fluid; and, allowing the consolidating fluid to consolidate formation particulates therein. The methods may be performed such that the percentage of consolidating agent varies over the course of the treatment or the rate of injection varies over the course of the treatment.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: providing an injection well wherein the injection well includes unconsolidated particulates in one or more formation intervals along a wellbore that accepts injection fluid; providing a consolidating treatment fluid comprising a base fluid and a consolidating agent wherein the consolidating agent comprises a tackifying agent present at a concentration of about 0.01% to about 1% by volume of the consolidating treatment fluid ; introdu…
