Description

    BACKGROUND OF THE INVENTION
  • [0001]
    1. Field of the Invention
  • [0002]
    The present invention relates to methods, aqueous treating fluid compositions and high ionic strength gelling agent polymers for treating subterranean formations.
  • [0003]
    2. Description of the Prior Art
  • [0004]
    Viscous treating fluids are used in a variety of operations and treatments in oil and gas wells. Such operations and treatments include forming gravel packs in well bores, fracturing producing zones, performing permeability control treatments and the like.
  • [0005]
    Hydrocarbon producing wells are often stimulated by hydraulic fracturing treatments. In hydraulic fracturing, a viscous fracturing fluid, which also functions as a carrier fluid, is pumped into a subterranean zone to be fractured at a rate and pressure such that one or more fractures are formed in the zone. Proppant particles, e.g., graded sand, for propping the fractures open are suspended in the fracturing fluid and are deposited in the fractures when the fracturing fluid viscosity is reduced. The fracturing fluid viscosity is reduced by including a delayed viscosity breaker in the fracturing fluid that causes it to revert to a thin fluid. The proppant particles deposited in the fractures function to prevent the fractures from closing so that conductive channels are formed through which produced hydrocarbons can readily flow.
  • [0006]
    Aqueous fracturing fluids are generally viscosified by mixing a hydratable polysaccharide gelling agent polymer with water. For example, guar gum and its derivatives are often used to viscosify aqueous fracturing fluids. Guar gum is a random coil polymer that can be readily crosslinked with various cross-linking agents, e.g., metal ions. Once crosslinked, guar and guar derivatives can form highly viscoelastic gels that approach near zero suspended particle settling rates.
  • [0007]
    It is desirable to increase the effectiveness of gelling agent polymers in general, and this has been achieved in the prior art to a significant degree by grafting ionic groups, for example carboxyl groups, onto the gelling agent polymer chain. Since like charges tend to repel each other, the carboxyl groups force the flexible coiled polymer to become more linear. Maximizing the linearity results in an enlarged radius of gyration, which in turn results in a lesser amount of gelling agent being required to generate a gelled treating fluid.
  • [0008]
    A problem is that the viscosity increasing effect of carboxyl groups is greatly reduced as the pH of the fluid drops below 7. This is due to the fact that the carboxylate ions are salts of weak acids and tend to hydrolyze. In addition, the solubility of anionic groups in water containing multivalent metal ions such as calcium and magnesium is small making gelling agent polymers containing anionic groups, e.g., carboxyl groups, less soluble in hard water. Thus, anionic groups render gelling agent polymers sensitive to ionic strength whereby the viscosity of the polymer in a salt solution is much less than the viscosity in fresh water. The salt sensitivity is undesirable since the aqueous liquids used in well treating fluids often contain chloride salts to inhibit swelling of formation clays or are formed with brines or seawater.
  • [0009]
    Thus, there are needs for improved methods of treating subterranean formations with viscous aqueous treating fluids, gelling agent polymers having decreased sensitivity to low pH and hard water, and improved gelling agent polymers having high ionic strength.
  • SUMMARY OF THE INVENTION
  • [0010]
    By the present invention, methods of treating subterranean formations with viscous aqueous treating fluids, improved viscous aqueous treating fluids and improved gelling agent polymers are provided which meet the needs described above and overcome the deficiencies of the prior art. The methods of treating subterranean formations penetrated by well bores basically comprise the following steps. A viscous aqueous treating fluid composition is prepared or provided comprising water and a high ionic strength gelling agent polymer. Thereafter, the viscous aqueous treating fluid composition is introduced into the subterranean formation.
  • [0011]
    The viscous aqueous treating fluid compositions of this invention comprise water and a high ionic strength gelling agent polymer. The high ionic strength gelling agent polymer is a sulfonated polymer that provides improved rheological properties to the treating fluid, as do conventional carboxylated gelling agent polymers. However, unlike carboxylated gelling agent polymers, the sulfonated gelling agent polymer maintains improved viscosity properties at pH's below 7 and in hard water.
  • [0012]
    The improved high ionic strength gelling agent polymers of this invention are sulfonated gelling agent polymers.
  • [0013]
    The objects, features and advantages of the present invention will be readily apparent to those skilled in the art upon a reading of the description of preferred embodiments which follows.
