Shares of companies in the petroleum industry fell for a sixth straight session Friday, but investors were spared more brutal losses. Oil-service shares gained.

The NYSE Arca Natural Gas Index dipped 0.2% to 490.
The Philadelphia Oil Service Index rose 0.5% to 175.

BP PLC (BP, BP.LN) fell 1.5% after it said it expects a revised spill-flow estimate from a government panel over the weekend from its Deepwater Horizon accident in the Gulf of Mexico. It may attempt a "top-kill" action to clog the well in coming days.
