Abstract
The present disclosure relates to subterranean formation operations and, more particularly, to embedded treatment fluid additives for use in subterranean formation operations. The embedded treatment additives may comprise an aqueous-soluble downhole reactive material embedded in a crosslinked polymeric solution to delay the reactivity of the aqueous-soluble downhole reactive material, thereby forming the embedded treatment additive, wherein the aqueous-soluble downhole reactive material is a solid.
Claims20
An embedded treatment additive comprising:
- an aqueous-soluble downhole reactive material embedded in a crosslinked polymeric solution to delay the reactivity of the aqueous-soluble downhole reactive material, thereby forming the embedded treatment additive, wherein the aqueous-soluble downhole reactive material comprises N-phosphonomethyliminodiacetic acid and is embedded in the crosslinked polymeric solution;
- and the crosslinked polymeric solution comprises polyvinyl alcohol;
- wherein the aqueous-soluble downhole reactive material is a solid particulate.
A system comprising:
- a tubular extending into a subterranean formation;
- and
- a pump fluidly coupled to the tubular, the tubular containing a treatment fluid comprising:
- an aqueous base fluid and an embedded treatment additive,
- wherein the embedded treatment additive comprises an aqueous-soluble downhole reactive material embedded in a crosslinked polymeric solution to delay the reactivity of the aqueous-soluble downhole reactive material, wherein the aqueous-soluble downhole reactive material comprises N-phosphonomethyliminodiacetic acid and is embedded in the crosslinked polymeric solution;
- and the crosslinked polymeric solution comprises polyvinyl alcohol;
- and
- wherein the aqueous-soluble downhole reactive material is a solid particulate.
