May 2 (Reuters) - U.S. oil and gas producer

ConocoPhillips ( COP ) missed Wall Street estimates for

first-quarter profit on Thursday, as demand concerns led to a

sharp fall in natural gas prices.

The Houston, Texas-based company posted adjusted earnings

of $2.03 per share for the quarter ended March 31, compared with

analysts' average estimate of $2.04 per share, according to LSEG

data.
