The present invention relates to a new structural class of phenalkamine, phenalkamine curing agent compositions, methods of making such phenalkamine, and methods of making such compositions. The phenalkamine curing agent compositions of the present invention can be prepared by reacting cardanol with an aldehyde compound and a mixture of methylene bridged poly(cycloaliphatic-aromatic)amines. These curing-agent compositions may be used to cure, harden, and/or crosslink an epoxy resin.

Methods and compositions for a foamed treatment fluid in a wellbore. A method of treating a lost circulation zone comprising: introducing a foamed treatment fluid into a lost circulation zone in a subterranean formation, wherein the foamed treatment fluid comprises: a cement; a viscosifying agent; a thixotropic additive; a foaming surfactant; a gas; and water; allowing the foamed treatment fluid to set in the lost circulation zone to seal the lost circulation zone. A foamed treatment fluid comprising: a cement; a viscosifying agent; a thixotropic additive; a foaming surfactant; a gas; and water.

Methods and systems of reducing lost circulation in a wellbore are provided. An example method includes providing a pozzolan slurry comprising a pozzolanic material and water; and providing a calcium slurry comprising a calcium source, a high pH activator, and water. The method further comprises allowing the pozzolan slurry and the calcium slurry to remain separate; wherein at least one of the pozzolan slurry and the calcium slurry comprise a thixotropic material; wherein at least one of the pozzolan slurry and the calcium slurry comprise a dispersant; wherein at least one of the pozzolan slurry and the calcium slurry comprise a weighting agent. The method additionally comprises mixing the pozzolan slurry and the calcium slurry to form a two-part thixotropic lost circulation slurry after the allowing the pozzolan slurry and the calcium slurry to remain separate. The method also includes introducing the two-part thixotropic lost circulation slurry to a lost circulation zone within the wellbore; and allowing or causing to allow the two-part thixotropic lost circulation slurry to set into a hardened mass within the lost circulation zone.

The present invention relates to methods of cementing, for example, an oil or gas well. The method may involve pumping a suspension of a filler mixture and at least about 5 weight percent of a thermosetting resin based on the total weight of resin and filler mixture. Advantages may include superior properties and reliability as compared to conventional cementing operations often involving Portland cement.
