| titleOfInvention | Organic titanium compositions for use in oil and gas wells |
| abstract | A dry, solid mixture of (a) the reaction product of (R<1>O)4Ti with (i) HgN(R<2>OH)k at a titanate: amino alcohol mol ratio of about 1:1, or (ii) R<3>[N(R<4>OH)mR5_n]2 at a titanate: amino alcohol mol ratio in the range between about 1:1 and about 2:1, and (b) a monosaccharide, disaccharide, or polyhydric alcohol which can be obtained by reduction of a monosaccharide, in an amount sufficient to enhance the uniform crosslinking capacit of said reaction product, wherein R1 is 61-6 alkyl; each of R<2>, R<3> and R<4> is 61-6 alkylene; R<5> is H or C1-6 alkyl; k is 1-3 and g plus k equals 3; and m is 1 or 2 and m plus n equals 2. Mixtures are useful in thixotropic cements and in fluid fracture formulations for oil wells. |
