A drilling fluid composition having a controlled viscosity with the addition of a polyamide as a rheology modifier. The polyamide having has an acid value from 10 mg KOH/g to 200 mg KOH/g is obtained from a reactant mixture comprising: one or more polycarboxylic acids and one or more polyamines. The polycarboxylic acid is selected from the group of polycarboxylic acids having a carboxylic acid functionality of two or more, an average number of carboxylic acid functionalities of from 2 to 4, and having from 2 to 60 carbon atoms, wherein at least one of the polycarboxylic acids is derived from a dimer fatty acid. The polyamine is selected from the group of polyamines having an amine functionality of two or more selected from the group of primary and secondary amino groups, an average number of amine functionalities of from 2 to 4, and having from 2 to 36 carbon atoms.

Drilling fluid compositions

Rosin esters are provided. The rosin esters can exhibit improved color (e.g., the rosin ester can have a neat Gardner color of 4 or less), improved oxidative stability (e.g., when 1000 ppm or less of an antioxidant is present in combination with the rosin ester, the rosin ester can exhibit an oxidative-induction time at 130&#xb0; C. of at least 30 minutes), improved color stability (e.g., the rosin ester can retain a neat Gardner color of 5 or less when heated to a temperature of 160&#xb0; C. for a period of three hours), or combinations thereof. Also provided polymeric compositions comprising the rosin esters, as well as methods of making the rosin esters.
