A valve assembly for downhole completion operations and method for using the assembly is described. The valve assembly relies on non-polymeric interfaces between the valve components for sealing the valves without elastomeric materials, thereby making the valve assembly suitable for high temperature well operations, such as 320° C. to 600° C. which are typically encountered in geothermal well operations. The valve assembly includes a first seat which receives an actuating member to actuate the opening of ports in the housing, thereby allowing for fluid injection into the formation adjacent the valve assembly through the ports. A seal assembly suitable for use in high temperature well operations is also described.

Downhole valve assembly

A well completion system for producing fluids from a wellbore provided in a subterranean reservoir is provided. The well completion system includes tubing segments connectable to one another along the wellbore. The tubing segments include injection segments provided along the wellbore in spaced-apart relation to each other, each injection segment has an injection valve toollessly operable between a closed configuration preventing fluid flow into the reservoir, and an open configuration allowing fluid flow into the reservoir. The tubing segments also include production segments provided along the wellbore in a staggered relation with respect to the injection segments and configured to allow fluids received from the reservoir to be produced from the reservoir. The tubing segments each are configured to include injection fluid passages and production fluid passages isolated from one another along the wellbore to enable synchronously injecting and producing fluids to and from the reservoir at respective fractured locations.

Fluid pressure-activated valve assembly with flow restriction and systems and methods for in situ operations

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.
