Additives for improving DRA injection

4. The composition of claim 3 , wherein the additive is about 1% to about 10% by weight of the composition.
5. The composition of claim 1 , wherein the composition results in at least 10% decrease of film formation in a pump head when compared to the drag reducing latex formulation injected through the pump head through a four hour time frame.
6. The composition of claim 5 , wherein the composition results in at least 50% decrease of film formation in a pump head when compared to the drag reducing latex formulation injected through the pump head through a four hour time frame.
7. The composition of claim 1 , wherein the additive is selected from the group consisting of 2,2,4-trimethyl-1,3-pentanediol diisobutyrate, dioctyl adipate, bis(2-ethylhexyl) adipate and combinations thereof.
8. The composition of claim 1 , wherein the drag reducing latex formulation comprises solid particles dispersed in an aqueous medium.
9. A composition comprising:
an acrylate drag reducing latex formulation; and
an additive, wherein the additive is selected from the group consisting of 2,2,4-trimethyl-1,3-pentane diol diisobutyrate, dioctyl adipate, bis(2-ethylhexyl) adipate, glyceryl tributyrate, trimethyl pentanediol monoisobutyrate, dibutyl phthalate, dioctyl phthalate, glyceryl triacetate, dioctyl azelate, epoxidized tallate, triisooctyl trimellitate, triisononyl trimellitate, epoxidized soybean oil, dibutyl phthalate, butyl benzyl phthalate, dihexyl phathalate, C 6 -C 11 phthalate, diisononyl phthalate, diisodecyl phthalate, ditridecyl phthalate and combinations thereof, wherein the additive is added in the range between 1% to 20% by weight.
10. The composition of claim 9 , wherein the composition results in at least 10% decrease of film formation in a pump head when compared to the acrylate drag reducing latex formulation injected through the pump head through a four hour time frame.
11. The composition of claim 10 , wherein the composition results in at least 50% decrease of film formation in a pump head when compared to the acrylate drag reducing latex formulation injected through the pump head through a four hour time frame.
12. The composition of claim 9 , wherein the additive is about 1% to about 10% by weight of the composition.
13. The composition of claim 9 , wherein the additive is selected from the group consisting of 2,2,4-trimethyl-1,3-pentanediol diisobutyrate, dioctyl adipate, bis(2-ethylhexyl) adipate and combinations thereof.
14. The composition of claim 9 , wherein the acrylate drag reducing latex formulation comprises solid particles dispersed in an aqueous medium.
15. A method comprising:
injecting a composition of claim 1 through a pump head,
wherein the composition produces at least 50% less film formation by a drag reducing latex formulation through a four hour time frame than injection of the composition through the pump head.
16. The method of claim 15 , wherein the drag reducing latex formulation is an acrylate drag reducing formulation.
17. The method of claim 16 , wherein the additive is selected from the group consisting of 2,2,4-trimethyl-1,3-pentanediol diisobutyrate, dioctyl adipate, bis(2-ethylhexyl) adipate and combinations thereof.
