Energy giant Shell (SHEL.L) expects second-quarter gas trading results to be "significantly lower" than in the previous quarter, it said on Friday.
In an update ahead of second-quarter results on July 27, the world's biggest liquefied natural gas (LNG) trader also flagged $3 billion in writedowns for the quarter, primarily driven by a 1% increase in the discount rate used for impairment testing.
It added that trading performance in its chemicals and products business was also expected be lower than in the first quarter, with the indicative refining margin forecast to drop to $9 a barrel from $15 a barrel.
U.S. rival Exxon also guided for lower refining margins this week.
