Method for recovering oil

A process for recovering oil from a subterranean oil-containing formation comprising at least the steps of:

• a) introducing solid particles and water into the subterranean oil-containing formation to obtain a solid particles-stabilized emulsion containing droplets, whereby water is the continuous phase and oil is the dispersed phase, and
• b) recovering said solid particles-stabilized emulsion from the subterranean oil-containing formation,
• wherein the solid particles comprise at least one layered double hydroxide of general formula (I)
• [MII(1-x)MIIIx(OH)2]x+[An−]x/n.yH2O (I),
• wherein
• MII denotes a divalent metal ion or 2Li,
• MIII denotes a trivalent metal ion,
• An− denotes an n-valent anion,
• n is 1 or 2,
• x is the mole fraction having a value ranging from 0.1 to 0.5 and
• y is a value ranging from 0 to 5.0;
• wherein the solid-particles stabilized emulsion has a viscosity at 20° C. in the range of 5 to 30 mPa·s at a temperature of 20° C. under shear rate of 10/s.
