Abstract: Embodiments relate to a method of enhanced oil recovery that includes injecting a composition including an hyperbranched polyglycerol into an injection well in a subterranean oil-bearing reservoir, the hyperbranched polyglycerol being a primary alcohol that is a reaction product of a C2 to C25 carbon alcohol and a plurality of glycidols; and displacing oil in the subterranean oil-bearing reservoir using the composition.
