Abstract
A fluid composition which is able to exhibit elastic turbulence while pumped through a flow path which compels changes of direction of flow streamlines and comprise a solution of two or more flexible linear polymers in two categories. The first category has an average molecular weight of at least 10 MegaDaltons and the second category has an average molecular weight in a range from 0.25 to 5 MegaDaltons. The concentration of the first polymer is sufficient to enable elastic turbulence with or without the second category. The concentration of the second category is greater than that of the first. When flowing under low shear towards or away from a chamber where the flow path will induce elastic turbulence, the second category polymer reduces elastic instabilities and consequent pressure drop, thereby reducing pumping energy requirement.
