Diverter fluid diverter fluid
A diverter fluid having a carbon-containing particulate dispersed therein for controlling fluid flow within subterranean formations. The diverter fluid can be injected into a wellbore for formation of a filter cake by the carbon-containing particulate, and which disperses in hydrocarbons for return to the surface.
1. A method comprising:
introducing into a wellbore from an Earth's surface of a well site a water based diverter fluid, the diverter fluid having a continuous aqueous phase and an oxygen functionalized carbon-containing particulate dispersed in the aqueous phase;
reducing the oxygen functionalized carbon-containing particulate;
forming, with the reduced oxygen functionalized carbon-containing particulate, a filter cake on a formation face; and
returning the reduced oxygen functionalized carbon-containing particulate to the surface of the well site dispersed in hydrocarbons produced from the wellbore.
2. The method of claim 1 , wherein the oxygen functionalized carbon-containing particulate is graphene oxide.
3. The method of claim 1 , further comprising introducing into the wellbore a reducing agent whereby, in the step of reducing, the oxygen functionalized carbon-containing particulate is reduced by the reducing agent.
4. The method of claim 3 , wherein the reduced oxygen functionalized carbon-containing particulate is reduced graphene oxide.
5. The method of claim 1 , wherein the oxygen functionalized carbon-containing particulate is dispersed in the continuous aqueous phase in the absence of a surfactant.
6. The method of claim 1 , wherein the oxygen functionalized carbon-containing particulate is made up of one or more carbon allotropes.
7. The method of claim 1 , further comprising agglomerating the reduced oxygen functionalized carbon-containing particulate within the wellbore to form the filter cake.
8. The method of claim 1 wherein the functionalized carbon-containing particulate is formed by grinding a carbon-containing material.
9. The method of claim 1 wherein the functionalized carbon-containing particulate is particulate other than nanotubes.
