| A valve seal assembly that provides for external pressure to be introduced to an energized seal of a valve, and compress the seal against a gate with enough force to block any paths where sand and chemicals would otherwise travel into valve body cavity or void. The external pressure introduced through pressure fitting makes the parts move like piston forcing the parts to compress together eliminating the machined tolerances or gaps required for the gate to be opened or closed. The compression can be provided by hydraulic pressure devices through injection ports. A separate valve seal assembly can be provided for each face of the gate and both assemblies can be activated when the fluids are flowing (open position) and an upstream valve seal assembly activated when the gate is in a closed position. | ||||||

The obstruction may be caused by another valve or valve assembly located in the production tubing string, where the valve is closed and blocks flow through the production tubing. The downhole valve assembly comprises a tubular body that includes an axial passage extending through the body and one or more ports extending substantially radially through the body. The downhole valve assembly also includes one or more actuating members operable to move relative to the body. Movement of the actuating members selectively opens the ports such that a fluid flow path through the ports is defined between an annulus region outside of the valve assembly and the axial passage such that the blockage can be bypassed. | ||||||

| Existing BOP devices are complex electromechanical systems exploiting hydraulic activation of pipe rams and/or shear rams. With tens of thousands of oil wells in the 1,500 oil fields that account for 97% of global production of the over 40,000 oil fields identified to date and failure rates as high as 50% in disaster situations it is evident that a simpler, increased reliability approach would be beneficial to the oil and gas industries. It would be further beneficial if the BOP was automatic requiring no monitoring locally to the BOP or remotely from the rig or production facility. | ||||||
