Siloxane surfactant additives for oil and gas applications

A well treatment additive comprising:

• a siloxane surfactant, wherein the siloxane surfactant has a formula selected from the group consisting of:
• MDa(D′R1)bM (formula 1) and (M′R1)Da(M′R1) (formula 2)
• wherein “R1” represents an organic radical comprising —(CH2)n—(OCH2CH2)x—(OCH(CH3)CH2)y—OR3, in which “n” is between 3 and about 11, “x” is between 3 and about 30, “y” is between 1 and about 30, and “R3” is —H;
• wherein “M” represents Me3SiO1/2, D represents -Me2SiO—, “M′R1” represents Me2(R1)SiO1/2—, “D′R1” represents -Me(R1)SiO—, and “Me” represents —CH3;
• wherein for formula 1, “a” is 0-200 and “b” is 1-20;
• wherein for formula 2, “a” is 4-50;
• a nonionic surfactant in an amount between about 5 wt % and about 70 wt % versus the total well treatment additive, wherein the nonionic surfactant is selected from the group consisting of linear alcohol ethoxylates, polyoxyethylene alkylphenol ethoxylates, polyoxyethylene alcohol ethoxylates, polyoxyethylene esters of fatty acids, polyoxyethylene alkylamines, alkyl polyglucosides, ethylene oxide—propylene oxide copolymers, and combinations thereof;
• a solvent, wherein the solvent is a terpene hydrocarbon in an amount between about 5 wt % and about 40 wt % versus the total well treatment additive;
• and
• an aqueous phase, wherein nano-sized particles of the solvent are distributed within the aqueous phase.
