April 9 (Reuters) - BP said on Tuesday it expects first-quarter upstream production of both oil and gas as well as low-carbon energy to be higher than the previous three months.

The London-listed oil major also expects strong results in oil and gas trading, along with a $100 million-$200 million boost from improved oil refining margins.

The company published its trading update ahead of its results which are due on May 7.

Last week, rival Shell said in its first-quarter trading update that it expects significantly lower results from liquefied natural gas trading. (Reporting by Yadarisa Shabong and Deep Vakil in Bengaluru; editing by Shounak Dasgupta and Jason Neely)
