| 发明名称 | Method for the removal or suppression of interfering metal ions using environmentally friendly competitive binders | ||
| 摘要 | 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. | ||
