    Abstract: The present invention provides strategies for making higher weight, cyclic polyamines from lower molecular weight, cyclic polyamine starting compounds via transamination. The higher molecular weight, cyclic polyamines are structurally similar to the lower molecular weight, cyclic polyamine starting compounds. The reactants used in the present invention include a cyclic polyamine component that comprises at least two amine groups separated from one another by at least a binary carbon atom spacing, and that can be transaminated to form a higher molecular weight, cyclic polyamine compound. The higher molecular weight, cyclic polyamine has at least two cyclic rings joined to one another through a nitrogen-containing hydrocarbyl group. Each of the cyclic rings contains two amine groups separated from one another by binary carbon atom spacing.

    Abstract: The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent having the formula: (Formula I should be inserted here.) wherein R is hydrogen or an alkyl group having 1 to 12 carbons, R1 is an alkylene group having 1 to 12 carbons, and R2 is an alkyl group having 1 to 12 carbons. The shale hydration inhibition agent should be present in the aqueous based drilling fluid in sufficient concentration to reduce the reactivity, such as swelling, of clays and shale when exposed to water-based drilling fluids.
