A downhole fluid comprises a base fluid, for example a hydrocarbon base fluid, and a pyromellitamide gelling agent. The pyromellitamide gelling agent may have the general formula of: n nwith R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 each being a hydrogen or an organic group. R1, R2, R3 and R4 may each be hexyl groups or may each be octyl groups. A composition for gelling a downhole fluid, the composition comprising a pyromellitamide gelling agent and a wetting agent. |
