Abstract: The present invention relates to methods for hydraulically fracturing a subterranean formation to improve the production rates and ultimate recovery by contacting unconsolidated resin-coated proppant particulates residing in a propped fracture with a reactive crosslinker in order to form a consolidated proppant pack. The present invention also relates to methods for use in water injection wells to consolidate the resin-coated proppant particulates in a gravel packed or frac packed region of a wellbore.

Abstract translation: 本发明涉及通过将驻留在支撑裂缝中的未固化树脂涂覆的支撑剂颗粒与反应性交联剂接触以形成固结的支撑剂组合物来水压破碎地层以提高生产率和最终回收的方法。 本发明还涉及在注水井中使用的方法，以将在树脂涂覆的支撑剂颗粒固结在井筒的砾石填充或压裂填充区域中。
