Abstract
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.
Claims20
A method of preventing or minimizing communication between adjacent wells comprising:
- providing a pre-pad fluid comprising a diverting agent;
- a silica gel;
- a hydraulic cement;
- and a conformance chemical selected from a monomer, a non-crosslinked polymer, a crosslinkable polymer system, a resin, and a silicate;
- introducing the pre-pad fluid into a first well adjacent a second well;
- providing a pad fluid comprising the conformance chemical, the diverting agent, the silica gel, and the hydraulic cement;
- introducing the pad fluid into the first well at a rate and pressure sufficient to initiate or extend a fracture in the first well after introducing the pre-pad fluid;
- allowing the conformance chemical, the diverting agent, the silica gel, and the hydraulic cement to block fractures in the first well and thereby preventing or minimizing communication between the first well and the second well;
- and
- recovering a formation fluid from the first well, the second well, or both.
A method of preventing or minimizing communication between adjacent wells comprising:
- mixing a diverting agent;
- a silica gel;
- a hydraulic cement;
- and a conformance chemical selected from a monomer, a non-crosslinked polymer, a crosslinkable polymer system, a resin, and a silicate with a fluid to form a pre-pad fluid and a pad fluid;
- introducing the pre-pad fluid and then the pad fluid into a first well adjacent a second well, wherein the first well was drilled later than the second well and the pad fluid is introduced into the first well at a rate and pressure sufficient to initiate or extend a fracture in the first well;
- introducing a flush fluid, after introducing the pad fluid, into the first well;
- allowing the conformance chemical, the diverting agent, the silica gel, and the hydraulic cement to block fractures in the first well and thereby preventing or minimizing communication between adjacent fractures in the first well and the second well;
- and
- recovering a formation fluid from the first well, the second well, or both.
A method of preventing or minimizing communication between adjacent wells comprising:
- providing a pre-pad fluid comprising a crosslinkable water soluble polymer, a hydraulic cement, a silica gel, and a degradable polymer;
- introducing the pre-pad fluid into a first well adjacent a second well, wherein the first well was drilled later than the second well;
- providing a pad fluid comprising the crosslinkable water soluble polymer, the hydraulic cement, the silica gel, and the degradable polymer;
- introducing the pad fluid into the first well at a rate and pressure sufficient to initiate or extend a fracture in the first well after introducing the pre-pad fluid;
- allowing the crosslinkable water soluble polymer, the hydraulic cement, the silica gel, and the degradable polymer to block fractures in the first well and thereby preventing or minimizing communication between the first well and the second well;
- and
- recovering a formation fluid from the first well, the second well, or both.
