Abstract
A two part epoxy resin system is surface mixed in a method of remediating an active well. This surface mixed epoxy resin is then placed in the well at the desired remediation depth. Finally, the mixture in situ forms a cement plug.
Claims5
A method of remediating a well having a well fluid residing in the well, the method comprising:
- (A) providing an epoxy resin component and an activator component, wherein the epoxy rein component and the activator component would if mixed have a density less than the density of the well fluid;
- (B) surface mixing the components and at least one weighting agent to form an epoxy system, wherein the system has a density greater than the density of the well fluid;
- and
- (C) placing the system in the well to be remediated.

- (B) surface mixing the components and at least one weighting agent to form an epoxy system, wherein the system has a density greater than the density of the well fluid;
- (C) placing the system in the well to be remediated;
- and
- (D) allowing the mixture to form a cement plug.
2 more elements
A remediated well comprising:
- a well bore of an active well having a well fluid;
- and an epoxy mixture residing in the well bore, wherein the epoxy mixture comprises a weighting agent, an epoxy component and an activator component wherein if the epoxy component and the activator component were mixed have a density less than the density of the well fluid, and wherein the epoxy mixture has a density greater than the density of the well fluid.
