BG announces first gas from Dolphin Deep field in Trinidad and Tobago
Stock Exchange Announcement	19 July 2006

BG Group and its partner Chevron today announced the delivery of first gas from the Dolphin Deep development to the onshore processing facilities at Beachfield on the south east coast of Trinidad and Tobago.

The BG operated Dolphin Deep field is located approximately 83 kilometres off the east coast of Trinidad in the East Coast Marine Area (ECMA). Gas production from the two Dolphin Deep wells is expected to reach a maximum rate of 250 million standard cubic feet per day (mmscfd) and will be delivered to Atlantic LNG (ALNG) in Port Fortin on the south west coast via two recently completed pipelines - the 95 kilometre (km) offshore Dolphin to Beachfield Pipeline, and the 76 km onshore Cross Island Pipeline (CIP).

Martin Houston, Executive Vice President North America, Caribbean and Global LNG, said:

"By bringing the Dolphin Deep field on stream, BG Group and its partner have completed the first sub-sea development in Trinidad and Tobago. Gas from this development will feed some of BG Group’s supply rights in Atlantic LNG, which continues to be the leading supplier of LNG to the USA."
