Abstract
Official abstract text for this publication.
The present invention relates to environmentally friendly compositions and methods for removing or suppressing metal ions in waters, flowback waters, and produced waters to make such waters suitable for subsequent use in oil-field applications and for delinking metal cross-linked gelling agents. One embodiment of the present invention provides a method of providing a competitive binder and allowing the competitive binder to interact with interfering metal ions in a flowback fluid to suppress or remove interfering metal ions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: providing a competitive binder grafted to a solid surface; and allowing the competitive binder produced from a wellbore to interact with interfering metal ions in a flowback fluid to remove interfering metal ions. 2. The method of claim 1 further comprising: using the flowback fluid to form a treatment fluid or disposing of the flowback fluid. 3. The method of claim 2 wherein the trea…
