  • Well service fluid and method of making and using the same
    Patent number: 7326670
    Abstract: A well service fluid comprising one or more anionic viscoelastic surfactants and one or more polymers is described. The fluids can contain an aqueous or non-aqueous fluid and/or a buffer for adjusting the pH of the fracturing fluid. The well service fluid can be used as a fracturing fluid in order to control water production from a well, while simultaneously increasing the oil production from the well.

  • Multi-functional additive for use in well cementing
    Patent number: 6235809
    Abstract: This invention relates to a cement composition for cementing oil, gas and geothermal wells comprising: a cement; and an additive comprising a blend of a sodium silicate; water; a carrageenan suspending agent; a sodium polyacrylate; an AMPS terpolymer; a dispersant; and a cellulosic water soluble polymer. The dispersant may comprise a sulfonated naphthalene formaldehyde condensate or a sulfonated ketone acetone formaldehyde condensate. The cellulosic water soluble polymer may comprise HEC or CMHEC. The invention can also function to reduce the occurrence of gas channelling and stabilize foam created by adding nitrogen gas to cement.
