April 10 (Reuters) - Shale producer Occidental Petroleum ( OXY )

said on Friday its worldwide average realized oil prices

fell about 1.6% year-on-year in the first quarter, despite

higher benchmark crude rates amid Middle East-related energy

market disruption.

The U.S.-Israel war on Iran has caused a massive disruption

of energy supplies as the Strait of Hormuz, a conduit for a

fifth of global energy flows, has been effectively closed.

Benchmark Brent crude prices averaged $89.62 per

barrel during the first quarter, up from $75.16 during the same

period last year, according to LSEG data.

* Occidental's worldwide average realized oil price in the

first quarter of 2026 was $69.91 per barrel, compared with

$71.07 a barrel a year earlier.

* Worldwide realized natural gas prices averaged $1.20 per

million cubic feet in the quarter, almost halving from $2.30 per

mcf last year.

* Worldwide realized natural gas liquids prices decreased

27% to $18.99 per barrel from $25.94 per barrel in the previous

year.
