The 11 members of The Organization of the Petroleum Exporting Countries (OPEC) increased crude oil production by 100,000 barrels per day (bpd) in July.
The ramp-up reaches 28.57 million bpd, an increase from the 28.47 million bpd pumped in June.
Excluding Iraq production from the 11 members bound by quotas rose up by 80,000 bpd to 26.12 million bpd in July from 26.04 million bpd in June, a survey by Platts showed.
OPEC output fell steadily in August 2008 and the economic squeeze diminished demand before April. Production lifted in April, May and June. However, the OPEC-11 failed to bring their volumes down to the 24.845 million bpd target which came into effect on 1 January this year.
Saudi Arabia elevated output by 50,000 bpd, the survey found. Smaller increases came from Nigeria (30,000 bpd), Iraq (20,000 bpd), and Venezuela (10,000 bpd). Angolan volumes dipped slightly.
