Methods for reducing fluid communication between wells

A method of reducing fluid communication between wells:

• providing a first treatment fluid comprising synthetic clay and an aqueous carrier fluid;
• pumping the first treatment fluid into a first fracture network in fluid communication with a first well;
• placing the synthetic clay in the first fracture network;
• pumping a second treatment fluid into a second fracture network in fluid communication with a second well;
• wherein the second treatment fluid is not produced in the first well, and wherein the second fracture network is in fluid communication with the first fracture network.

A system for reducing fluid communication between wells:

• a first treatment fluid comprising synthetic clay and an aqueous carrier fluid;
• a first well in fluid communication with a first fracture network;
• a second well in fluid communication with a second fracture network;
• a pump and mixer system capable of pumping the first treatment fluid into the first fracture network or the second fracture network;
• and
• wherein the first fracture network and the second fracture network are in fluid communication.
