Abstract (en)
[origin: WO2014146191A1] A downhole fluid comprises a base fluid, for example a hydrocarbon base fluid, and a gelling agent. The gelling agent has an aromatic core of one or more aromatic rings, the gelling agent having two or more amide branches distributed about the aromatic core, each of the two or more amide branches having one or more organic groups. An example gelling agent is a pyromellitamide gelling agent. The pyromellitamide gelling agent may have the general formula of (I) with R1, R2,R3, R4, R5, R6, R7, and R8 each being a hydrogen or an organic group. Methods of use and composition are discussed.
