Abstract
Systems and methods are directed to proppant flowback control. A method includes coating resin onto proppant at a well site and pumping the coated proppant into a wellbore during a fracking operation. The method further includes pumping an activator for the resin into the wellbore to displace the coated proppant into at least one fracture during the fracking operation. The pumping of the coated proppant and the pumping of the activator are performed separately.
Claims20
A method comprising:
- coating resin onto proppant at a well site to provide coated proppant;
- pumping the coated proppant into a wellbore during a fracking operation;
- pumping an activator for the resin into the wellbore, the activator configured to harden the resin to consolidate loose particles;
- flushing the coated proppant into at least one fracture with the activator during the fracking operation, wherein the pumping of the coated proppant and the pumping of the activator are performed separately;
- introducing a plug and a perforating apparatus into the wellbore, wherein the plug is attached to the perforating apparatus;
- and
- pumping the plug and the perforating apparatus along the wellbore;
- and
- displacing the activator in a downhole direction with the plug.

A method comprising:
- coating resin onto proppant at a well site to provide coated proppant;
- pumping the coated proppant into at least one fracture extending from a wellbore;
- pumping an activator for the resin into the wellbore, wherein the pumping of the coated proppant and the pumping of the activator are performed separately, the activator configured to harden the resin to consolidate loose particles;
- positioning a perforating tool in the wellbore;
- and
- displacing the activator from the wellbore into the at least one fracture with a plug that is attached to the perforating tool.

A method comprising:
- coating resin onto proppant at a well site to provide coated proppant;
- pumping the coated proppant into at least one fracture extending from a wellbore;
- setting a plug in the wellbore;
- positioning a tool with a bit in the wellbore;
- and
- pumping an activator for the resin into the wellbore while milling the plug with the bit, wherein the pumping of the coated proppant and the pumping of the activator are performed separately, the activator configured to harden the resin to consolidate loose particles.
