Patent Number Title Of Patent Date Issued
4861500 Delayed crosslinker composition containing organic titanium complexes and hydroxycarboxylic acid August 29, 1989
A crosslinker composition that can produce delayed crosslinking of an aqueous solution of a crosslinkable organic polymer. The composition comprises an organic titanium complex. The composition further contains an organic hydroxycarboxylic acid, preferably hydroxyacetic acid. The pH of
4797216 Delayed crosslinker composition January 10, 1989
A crosslinker composition that can produce delayed crosslinking of an aqueous solution of a crosslinkable organic polymer. The composition comprises a metal compound, preferably an organic metal complex, and most preferably an organic zirconium complex. The composition further contains
4780223 Stabilized fracture fluid and crosslinker therefor October 25, 1988
Various organometallic crosslinkers containing titanium or zirconium atoms in the +4 oxidation (valence) state have been used to crosslink solvatable polysaccharides (e.g., hydroxypropyl guar) in aqueous media. The crosslinked gels are useful as fracturing fluids. Aqueous solutions of th
4749041 Hydraulic fracturing method using delayed crosslinker composition June 7, 1988
A crosslinker composition that can produce delayed crosslinking of an aqueous solution of a crosslinkable organic polymer. The composition comprises a metal compound, preferably an organic metal complex, and most preferably an organic zirconium complex. The composition further contains
4749040 Method of fracturing a subterranean formation using delayed crosslinker compositions containing June 7, 1988
A crosslinker composition that can produce delayed crosslinking of an aqueous solution of a crosslinkable organic polymer. The composition comprises an organic titanium complex. The composition further contains an organic alpha-hydroxymonocarboxylic acid, preferably hydroxyacetic acid.
4686052 Stabilized fracture fluid and crosslinker therefor August 11, 1987
