Nexus Shuts in Longtom after Mercury Found in Gas

Nexus Energy halted production at its Longtom field after low levels of mercury were detected in gas produced by the Longtom-4 well. Test samples were acquired from the Longtom-3 well over the weekend, and if test results confirm acceptable mercury levels, gas production will recommence. If not, the operator will have to install mercury-removal equipment, which will take at least two months and cost about US $1.8 million (A $2 million). During the installation period, production will be deferred. Longtom is situated in a water depth of 184 feet (56 meters) offshore Gippsland Basin, Australia in exploration permit VIC/P54.
