Methods of generating a surfactant composition from natural oil and utilizing greenhouse gas in its manufacture are described. The methods involve the reaction of a lipophilic cyclic carbonate functionalized material with a functionalized amine to form the surfactant. The surfactant has a significant level of biobased carbon content and utilizes either petroleum-derived, biobased, or fermentation-derived greenhouse gas in its manufacture.

The present disclosure provides derivatives of amino acids that have surface-active properties. The amino acid can be naturally-occurring or synthetic, or they may be obtained via a ring-opening reaction of a lactam, such as caprolactam. The amino acid may be functionalized to form a compound that is surface-active and have advantageous surfactant characteristics. The compounds of the present disclosure have low critical micelle concentrations (CMC) as well as superior ability to lower the surface tension of a liquid.

Stabilized foams are provided, adapted in particular for subterranean applications in hydrocarbon recovery operations. The foams are stabilized with surfactant-decorated nanoparticles, and the decoration of the nanoparticles with surfactant may be titrated to tune the stabilization of the foam.

Improved emulsifier for synthetic-based mud, process for preparation, and drilling method. The emulsifier has the formula (II) wherein each R.sup.1 is a C.sub.4 to C.sub.30 alkyl; R.sup.2, R.sup.3, R.sup.5, and R.sup.6 are each independently selected from H, C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkoxyalkyl, and C.sub.1 to C.sub.4 hydroxyalkyl; n and m are independently integers from 1 to 10; and y is an integer from 1 to 5. It is prepared by reacting a polyalkyleneamine with a monocarboxylic acid to form a first reaction product, reacting the first reaction product with a dicarboxylic acid to form a second reaction product, and heat treating the second reaction product to form an isomer. The drilling fluid contains the emulsifier, an oleaginous phase, and a non-oleaginous phase, and during use is circulated in a wellbore.
