Abstract
A method of enhanced oil recovery may comprise placing into a subterranean formation a production enhancement fluid comprising a short chain hydrocarbon phase and a silane based wettability modifier, wherein the short chain hydrocarbon phase comprises hydrocarbons having 5 or less carbon atoms; allowing the production enhancement fluid to remain in the subterranean formation for a shut-in period; and producing hydrocarbons from the subterranean formation.
Claims12
A production enhancement fluid, the fluid comprising:
- short chain hydrocarbon phase comprising hydrocarbons having 5 or less carbon atoms;
- an aqueous fluid;
- and
- a silane based wettability modifier, wherein the silane based wettability modifier comprises a combination of:
