The BG Group drilled two wells in 2000: Gaza Marine-1 and Gaza Marine-2. Reserves are estimated by British Gas to be of the order of 1.4 trillion cubic feet, valued at approximately 4 billion dollars. These are the figures made public by British Gas. The size of Palestine's gas reserves could be much larger.
In 2006, British Gas "was close to signing a deal to pump the gas to Egypt." (Times, May, 23, 2007). According to reports, British Prime Minister Tony Blair intervened on behalf of Israel with a view to shunting the agreement with Egypt.
The decision to speed up negotiations with British Gas (BG Group) coincided, chronologically, with the planning of the invasion of Gaza initiated in June. It would appear that Israel was anxious to reach an agreement with the BG Group prior to the invasion, which was already in an advanced planning stage.
