        BG Group finalises agreement to meet natural gas demand in Chile


BG Group today announced that it has signed an agreement to supply Chile's first
Liquefied Natural Gas (LNG) import terminal.


The 2.5 million tonnes per annum (mtpa) terminal in Quintero Bay - approximately
110 kilometres northwest of Santiago - will have the capacity to meet up to 40%
of the country's demand for natural gas. BG is a 40% shareholder in the
regasification terminal which is targeted to commence operation in the second
quarter of 2009.


BG executed the 21-year LNG sale and purchase agreement to supply Chile with 1.7
mtpa of LNG through the terminal, to be supplied from the company's global LNG
portfolio.


Rick Waddell, BG Executive Vice President, South America said:


"Chile has a vibrant and growing economy which needs new gas supplies and we are
ideally placed to work with our Chilean partners to meet that demand.


"The Quintero LNG project expands our South American operations and provides a
long-term counter-seasonal market for our LNG portfolio. We are delighted to
have finalised our investment and participation in Chile's first LNG import
terminal. "


Background


GNL Quintero SA (GNLQ) is the project company which will own and operate the
terminal. In addition to BG's 40% shareholding, the other partners in the
project are the Chilean national oil and gas company ENAP (20%), power company
Endesa Chile (20%) and gas distribution company Metrogas (20%).


GNLQ today also entered into agreements for the provision of regasification
services at the terminal and for the onward sale of the terminal's regasified
natural gas.


The US$775 million engineering, procurement and construction contracts have been
awarded to CB&I.
