Royal Dutch Shell today has today reported a 15% fall in core earnings in the third quarter.
The company said that falls in the price of gas and oil more than offset gains stemming from cost savings and production increases.
It said earnings on the industry standard "current cost of supplies" measure were $6.13 billion, down from $7.24 billion in the same period a year ago.
This strips out the impact of fluctuations in oil prices between when it is produced and when it is sold.
However, prices were lower than a year ago, partly because of the global economic uncertainty.
Net profit was $7.14 billion, up slightly from $6.98 billion in the same period a year ago, reflecting one-time losses a year ago. Sales fell 8.9% to $112 billion.
