Methods of preventing or minimizing communication between adjacent wells include providing a treatment fluid including a conformance chemical, a diverting agent, and a hydraulic cement, introducing the treatment fluid into a first well adjacent a second well, allowing the conformance chemical, the diverting agent, and the hydraulic cement to block fractures in the first well to prevent or minimize communication between the first well and the second well, stimulating the second well after blocking the fractures, and recovering a formation fluid from the first well, the second well, or both.
