  • Enhancing fluid removal from fractures deliberately introduced into the subsurface
    Patent number: 6069118
    Abstract: The present Invention relates to hydrocarbon well stimulation, and more particularly to methods and compositions to remove (or more generally to transfer) fluid introduced into a subsurface fracture, in which the methods involve creating then exploiting chemical potential gradients at the fracture face to induce fluid flow from the fracture into the formation; the methods and compositions involve creating, or relying upon an intrisic or previously created, a selectively permeable membrane that is permeable to water but that does not allow solutes to pass through.

  • High temperature guar-based fracturing fluid
    Patent number: 4801389
    Abstract: A fracturing fluid based on quar gum exhibiting good viscosity and stability at temperatures from about 80.degree. C. to at least about 120.degree. C. The fracturing fluid includes a guar gum, a zirconium or hafnium cross-linking agent, and a bicarbonate salt in an aqueous solution at a pH from about 8 to about 10.
