Abstract

There is disclosed a process for transporting fracture fluid additives underground to oil and gas wells by attaching a fracture fluid additive to an ion exchange resin and flowing the ion exchange resin underground and thereafter releasing the frac fluid additives from the ion exchange resins and also there is provided the use of an ion exchange resin as a proppant and a frac fluid lubricant.

Claims (11)

1. A process comprising:

providing an ion exchange resin having at least one frac fluid additive being operably attached thereto,

depositing said ion exchange resin underground, and

detaching said at least one frac fluid additive attached to said ion exchange resin from the ion exchange resin,

wherein said frac fluid additive is 2-phosphonobutane-1,2,4-tricarboxylic acid.

2. The process according to claim 1 , wherein said ion exchange resin is a crosslinked, weakly basic, monodisperse, macroporous, anion exchange polystyrene resin being functionalized with tertiary amine groups.

3. The process according to claim 1 , wherein said depositing step comprises adding the ion exchange resin to a frac fluid aboveground and thereafter flowing said frac fluid underground.

4. The process according to claim 3 wherein said underground is subterranea.

5. A process for increasing the lubricity of a frac fluid, comprising:

providing an ion exchange resin having at least one frac fluid additive attached thereto, wherein said frac fluid additive is 2-phosphonobutane-1,2,4-tricarboxylic add, and

contacting said ion exchange resin with said frac fluid.
