MEXICO CITY, Aug 26 (Reuters) - Mexican state oil firm

Pemex's newest refinery processed some 65,046 barrels

per day of crude oil in July, its first month of operations

after multiple delays, and just over 30,000 bpd of diesel and

coke.

The Olmeca refinery's production included 21,511 bpd of

diesel and 8,775 of coke, Pemex said in a recent report, but no

gasoline.

With a maximum processing capacity of 340,000 bpd, the

refinery in the Gulf port of Dos Bocas in Tabasco state is

Pemex's seventh Mexican refinery. The new capacity helped the

producer process some 1.01 million bpd this month.

This is 145,589 bpd more than Pemex produced in June and the

second month this year its output has surpassed 1 million bpd.

Olmeca was inaugurated in 2022 and its start-up has been

delayed multiple times since, while its $16.6 billion price tag

has more than doubled the initial government announcement. Pemex

is the world's most indebted oil firm.

Mexico's government hopes the refinery will help the country

eventually achieve self-sufficiency in gasoline and diesel,

allowing it to stop importing these products.

However, Pemex has said it is experiencing production

declines in key fields and has made fewer significant

discoveries.

Pemex Chief Executive Octavio Romero said earlier this month

that Olmeca should be producing at its full capacity as of Aug.

21, putting out 175,000 bpd of gasoline and 130,000 bpd of

diesel - a difficult figure to reach according to experts.

Olmeca has repeatedly missed production targets.

Pemex's July output consisted chiefly of heavily-polluting

fuel oil at 333,172 bpd, followed by gasoline at 287,878 bpd and

diesel with 205,326 bpd. This brought monthly output to 1.07

million bpd per month, from 907,267 bpd in July last year.

Crude oil output slipped to 1.497 million bpd, bringing

crude plus condensate output to 1.77 million bpd, the lowest

level this year and down from 1.86 million bpd the same month

last year.

Despite rising slightly from June, July's crude exports also

dipped 26% year-on-year to 779,000 bpd.
