Wellhead outlet reengineered for high-heat wells

The reengineered wellhead outlet shown on the left promises to operate safely in higher temperatures typically generated by the majority of high pressure, high temperature wells.

The unit is used to connect downhole cable to the surface telemetry system. The downhole cable terminates in a pressure bulkhead and then connects to the surface cable. This ensures that if, for any reason, the downhole cable is ¿¿ ooded, the integrity of the wellhead is maintained. It is used in permanent completions where pressure and temperature must be continuously monitored.

New, nonmetallic valve for highly corrosive processes

A nonmetallic valve designed for highly corrosive processes is on the market.

Constructed of nonmetallic, corrosionresistant materials, the company says its valves will operate in highly caustic environments not suitable for metal and fiberglass. The all-polymer internal construction enables the valves to operate in harsh chemicals, suiting them for use with chlorine, ethylene dichloride, and hydrochloric acid.

Polymer valves operate in a similar fashion to their metal and fiberglass counterparts, the firm notes. Valves protect low-pressure atmospheric storage tanks from excessive pressure and-or vacuum and limit fugitive emissions by preventing constant tank breathing to atmosphere. The relief valve is available in vent to atmosphere or pipe-away con gurations.
