Summary: | Methods for making emulsifiers, emulsified drilling fluids, and methods for using the same are provided. In one or more embodiments, the method for making an emulsifier can include mixing a tall oil and a triamide. The triamide can have the chemical formula:
where:
x, y, and z are integers independently selected from 1 to 10,
R 1 is a C 8 -C 20 alkyl, a C 8 -C 20 alkenyl, a C 8 -C 20 dialkenyl, or a C 8 -C 20 alkynyl,
R 2 is H or
independently selected for each [(CH 2 ) x NR 2 (CH 2 ) y ] unit, where R 4 is a C 1 -C 3 alkylene or a C 1 -C 3 alkylene alcohol, and where at least one R 2 is
and
R 3 is a C 8 -C 20 alkyl, a C 8 -C 20 alkenyl, a C 8 -C 20 dialkenyl, or a C 8 -C 20 alkynyl. |
