EXXON OFFICIAL URGES PLANNING FOR NEXT OIL SURGE World governments should prepare for an inevitable significant increase in the price of oil as non-Middle East supplies diminish, Exxon Corp <XON> director and senior vice-president Donald McIvor said. Policymakers must also face up to the reality that the bulk of world oil reserves lies in the Middle East, he said in a speech prepared for delivery to the Australian Petroleum Exploration Association (APEA) annual conference. It appears ever more likely that new discoveries elsewhere will not change this fact, he said. McIvor said 37 of the world's 30,000 oil fields contain about 35 pct of all oil ever discovered. Only 11 of these 37 super-giant fields lie outside the Middle East and only five of the 37 have been discovered in the last 20 years, three of them in the Middle East, he said. He also said that since 1970, the world has been consuming 20 to 25 billion barrels a year while making discoveries at the rate of only 10 to 15 billion barrels a year. More than half of remaining proved reserves are in the Middle East, he said. McIvor said it was important to continue to search for oil outside the Middle East because each addition contributes to a diversity of supply desirable for global political and economic stability. "It is important to enhance the likelihood of home-country discoveries with measures such as non-discriminatory and stable taxation, and minimum regulation, together with opening up of acreage for exploration," he said. Increasing reliance on the Middle East will also boost the incentive to use natural gas and synthetic sources of petroleum, he added.
