Chevron in new Gorgon gas strike

Ongoing: construction work on Chevron's Gorgon LNG project

US explorer Chevron has made a further major gas discovery in the Greater Gorgon area off Western Australia to boost feedstock for its regional liquefied natural gas projects.

The Elfin-1 well drilled in the Exmouth Plateau area of the Carnarvon basin struck about 40 metres of net gas pay in the upper Mungaroo sands, the company said in a statement, while not revealing a resource estimate.

The probe was sunk by semi-submersible Atwood Osprey to a total depth of 3630 metres in a water depth of 1088 metres, about 170 kilometres north-west of Barrow Island in Block WA-268-P owned by the Gorgon joint venture of Chevron (50%), Shell (25%) and ExxonMobil (25%).

It marks Chevron’s 21st discovery off Western Australia since mid-2009 and president of its Asia Pacific E&P unit, Melody Meyer, said the string of finds gives the company a “robust gas portfolio” as it develops the Gorgon and Wheatstone LNG projects to meet future regional demand.

The company has added at least 7 trillion cubic feet of gas resources to its Australian portfolio, in addition to its existing volumes for the two schemes, and has earlier said it has 50 Tcf of gas resources in the Carnarvon basin.

The WA-268-P permit also includes the previous Chandon and Yellowglen discoveries that so far remain unallocated.
