  • Dynamic reduction of the moisture layer during the displacement of a viscoelastic fluid using a fluid with lower viscosity
    Patent number: 7201224
    Abstract: The invention relates to a method of optimizing the displacement of a viscoelastic fluid in a pore, tube, duct, channel, fracture, porous medium or interconnected latticework or in an interconnected assembly of pores, tubes, ducts, channels, cavities and/or fractures using a fluid with a lower viscosity. The inventive method consists in displacing the viscoelastic fluid using a displacing fluid which supplies a signal thereto comprising pressure pulses at an optimum frequency. In this way, the moisture layer between the displaced fluid and the walls of the pores, tubes, channels, cavities, fractures or porous medium is dynamically reduced during said displacement, thereby facilitating optimum extraction.
