An improved method of producing hydrocarbons from a subterranean formation
in which a solids-stabilized emulsion (SSE) is formed, the SSE comprising
oil as a first liquid, droplets of a second liquid suspended in the oil,
and solid particles that are insoluble in both the oil and the second
liquid at the conditions of the subterranean formation. The SSE with
dissolved gas is injected into the subterranean formation as a drive
fluid, and at least a portion of the SSE is placed into one or more area
of the subterranean formation having an in situ pressure sufficiently
lower than the selected partial pressure to permit evolution of at least
a portion of the gas from the oil. Furthermore, a method of making the
foamy SSE is also provided.
