Abrégé

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.
