In 1998, earnings before interest and taxes for Field Services decreased $81 million compared to 1997, primarily due to a decrease in average NGL prices of approximately $0.09 per gallon, or 25.7%. The decrease in earnings before interest and taxes was partially offset by $34 million of gains on sales of assets which are included in other income.

Earnings before interest and taxes for Field Services increased 3.3% in 1997 over 1996, primarily due to higher volumes as a result of acquisitions in 1996. Natural gas gathered and processed volumes increased 17.2%, and NGL production increased 37.8% in 1997 compared to 1996. Partially offsetting these increases were lower NGL prices of approximately $0.04 per gallon, or 8%, and higher natural gas prices.
