摘要:
The present description relates to processes and systems for asynchronous frac-to-frac operations for recovering hydro-carbons. The processes can include the use of injection-only and production-only valves that include a housing and at least one sleeve as well as flow restriction components, check valves, or other features. The flow restriction component can be a tortuous path provided in the sleeve. The check valves can be integrated into the sleeve or into the housing of the valve. Various different types of valve assemblies can be used and integrated with flow restriction components and/or check valves.
