Abstract
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: with R1, R2, R3, R4, R5, R6, R7, and R8 each being a hydrogen or an organic group. A method comprises introducing the downhole fluid into a downhole formation. A method of making a downhole fluid, the method comprising: combining a base fluid and a pyromellitamide gelling agent. A composition for gelling a downhole fluid, the composition comprising a pyromellitamide gelling agent and a wetting agent.
Claims30
A fluid formulated to be suitable for downhole uses, the fluid comprising a base fluid, a gelling agent, and an agent that comprises glycol to quicken gelling of the gelling agent in the base fluid for downhole uses, and the gelling agent is a pyromellitamide gelling agent that comprises an aromatic ring having four amide branches, each of the four amide branches having a carbon bond with the aromatic ring and each amide branch of the four amide branches has a side chain that is a hydrogen.
A downhole fluid comprising a base fluid and a pyromellitamide gelling agent, in which the pyromellitamide gelling agent has the general formula of:
- with R1, R2, R3, and R4 each being a hydrogen and R5, R6, R7, and R8 each being an octyl group;
- and further comprising an agent to quicken gelling of the gelling agent, wherein the agent to quicken gelling comprises a glycol.
