  • Method of improving recovery from hydrocarbon reservoirs
    Patent number: 8235113
    Abstract: A method of increasing the recovery of hydrocarbons from a highly fractured reservoir uses the steps of injecting into the reservoir a membrane-forming fluid to form a membrane over the surface of at least part of exposed formation, injecting into the reservoir a fluid to establish a chemical potential gradient across the membrane and letting fluid enter the formation across the membrane to increase the pressure inside the formation and to force additional hydrocarbon from the formation.
    Type: Grant
    Filed: August 20, 2007
    Date of Patent: August 7, 2012
    Assignee: Schlumberger Technology Corporation
    Inventors: Kevin England, Joseph Ayoub, Bernard Montaron, Matthew Miller
  • Method of fracturing a coalbed gas reservoir
    Patent number: 7819191
    Abstract: A method for stimulation of gas production from coal seams is described using a permeability modifier, such as a coal swelling agent, injected into the coal seams via a wellbore to reduce the permeability of the coal seams prior to a fracturing treatment.

  • Methods for controlling the rheological properties of viscoelastic surfactants based fluids
    Patent number: 7084095
    Abstract: It was found that the addition of polymers to viscoelastic surfactant base system allows to adjust the rheological properties of the base fluid. Depending in particular on one side of the ratio of the concentration of added polymer and the concentration of viscoelastic surfactant and on the other side of the molecular weight of the added polymer, the same polymer—or the same type of polymer—may perform different functions such as viscosity enhancer, viscosity breaker or viscosity-recovery enhancer.

  • Hydraulic fracturing method
    Patent number: 6776235
    Abstract: This invention relates generally to the art of hydraulic fracturing in subterranean formations and more particularly to a method and means for optimizing fracture conductivity. According to the present invention, the well productivity is increased by sequentially injecting into the wellbore alternate stages of fracturing fluids having a contrast in their ability to transport propping agents to improve proppant placement, or having a contrast in the amount of transported propping agents.

  • Hydraulic Fracturing Method
    Publication number: 20040023812
    Abstract: The invention relates to a method of fracturing a subterranean formation including injecting into a wellbore a fracturing fluid based on a liquid medium having a density higher than 1.3 g/cm3, thereby allowing the use of a surface pressure at least 10% smaller than the surface pressure required with a fracturing fluid based on a liquid medium having a density of about 1 g/cm3.
