  • Method for calculating the distribution of fluids in a reservoir
    Patent number: 5937363
    Abstract: The invention relates to a method for characterizing a hydrocarbon reservoir comprising a gas cap (1) and an oil zone (2) with respectively Scwg and Scwo as the water saturation in each zone. The zone is invaded by gas either by gas injection, gas cap expansion or because of evolution of dissolved gases. In the method, the decrease in the initial water saturation Scwo in oil zone (6) during the displacement thereof by the gas is taken into account, the decrease being gradual down to Scwg which is distinctly below Scwo.

  • Method for recovering oil from an underground formation
    Patent number: 4364431
    Abstract: Method for recovering oil from an underground formation consisting of blocks of relatively low permeability with an oil-wet pore space containing oil surrounded by a fracture network of relatively high permeability by supplying to the fracture network an aqueous solution of a surfactant adapted for decreasing the surface tension between water and oil and displacing the oil from the oil-wet pore space of the blocks.
