  • Publication number: 20230022332
    Abstract: 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.

  • Patent number: 11525334
    Abstract: A method, system and apparatus of optimizing operation of one or more tubing strings in a hydrocarbon well are provided. Each tubing string is located in a hydrocarbon well and has a plurality of valves. Each valve is actuatable between a fully open position and a fully closed position and is in communication with a respective zone of a formation defining a reservoir containing hydrocarbon material. The method includes characterizing an injectivity of one or more zones of the formation and determining an optimal operating schedule in accordance with the characterization. The optimal operating schedule comprises one or more valve configurations and an operating duration for each of the one or more valve configurations.

  • Patent number: 10151187
    Abstract: A hydrocarbon resource recovery system may include an RF source, and an RF antenna assembly coupled to the RF source and extending laterally within a wellbore in a subterranean formation for hydrocarbon resource recovery. The RF antenna assembly may include first and second tubular conductors, and a dielectric isolator coupled between the first and second tubular conductors to define a dipole antenna. The hydrocarbon resource recovery system may include solvent injectors within respective laterally extending wellbores extending transverse and above the RF antenna assembly and configured to selectively inject solvent into the subterranean formation adjacent the RF antenna assembly.
