  • Method of using gelled aqueous well treating fluids
    Patent number: 4304300
    Abstract: Gelled aqueous fluids, solid blends for forming such fluids and methods of using the fluids for treating wells are provided. The gelled fluids are stable over a broad temperature range and are comprised of water, a first hydratable polymer for increasing the viscosity of the fluid to a desired level at temperatures within a first lower range and a second hydratable polymer for maintaining the viscosity of the fluid at temperature within a second higher range.
    Type: Grant
    Filed: May 23, 1980
    Date of Patent: December 8, 1981
    Assignee: Halliburton Company

  • Oil well spacer fluids
    Patent number: 4217229
    Abstract: A high stability, nondamaging spacer fluid is provided containing readily available weighting agents such as calcium carbonate and iron carbonate dispersed in water using a polymer viscosifier, a salt inhibitor, a primary sulfonated dispersant and a secondary fatty acid amide dispersion. Conventional high density weighting agents can also be used. The spacer fluid is stable over a temperature range of about 32.degree.-300.degree. F. for extended periods with densities ranging from 11 to 17.6 pounds per gallon.

  • Oxygen scavenging methods and additives
    Patent number: 4059533
    Abstract: This invention relates to methods and additives for scavenging oxygen dissolved and entrained in liquids which are particularly suitable for removing dissolved and entrained oxygen from polymer-containing fluids used in drilling and completing well bores as well as water flood and other procedures carried out in the oil field. The oxygen scavenger additive is sodium dithionite or a mixture thereof with sodium dithionate dispersed in a liquid carrier such as a hydrocarbon.
