Earnings for the second quarter will be announced before the stock market opens on August 6, 2002.
Second-quarter 2002 aggregate production volumes averaged 68.7 million cubic feet (MMcf) equivalent per day, consisting of natural gas output of 43.4 MMcf per day and oil volumes of 4,222 barrels per day.
