The International Energy Agency (IEA) has put Iran's oil income in the first nine months of 2023 at about $34 billion, which was equivalent to 12 percent of OPEC's total income in this period, Shana reported.

According to The Iran Project,Based on the IEA data, the total oil revenues of the 13 OPEC members in the mentioned nine months stood at $281.2 billion.

The Islamic Republic’s in the mentioned period reached $33.9 billion, about two times the total oil revenue of the country in 2020.

According to the U.S. Department of Energy, Iran sold only $17 billion of oil in 2020 and the country’s oil income rose to $37 billion in 2021, while Iran's total income from oil sales in 2022 was $54 billion.

The report released by the U.S. Department of Energy earlier this month stated that Iran has been the top OPEC member in terms of production increase in 2023, with an increase of 330,000 barrels per day (bpd).

The U.S. Energy Information Administration (EIA) affiliated with the Department of Energy mentioned in its latest report that the total oil production of Iran was estimated at 2.87 million bpd at the end of 2023.

According to the mentioned entity, Iran’s oil production stood at 2.54 million bpd in 2022.

The figures show that total OPEC oil production was 26.89 million bpd in 2023 which shows 630,000 barrels fall year on year. OPEC produced 27.52 million bpd in 2022.

This report has put Iran's oil production in the last month of last year at 3.17 million bpd. Iran was the third-largest OPEC producer after Saudi Arabia and Iraq in December 2023.

The 330,000-bpd increase in Iran’s 2023 oil production indicates that sanctions have been ineffective on Iran's oil industry.

Back in June 2023, Bloomberg reported that the production and export of Iranian oil in 2023 reached record highs since the country came under U.S. sanctions more than five years ago.

The report published in late June 2023 stated that Iran was shipping the highest amount of crude in almost five years despite U.S. sanctions.

Bloomberg cited energy analysts as saying that Iran’s oil exports have surged to the highest level since the U.S. unilaterally re-imposed sanctions on the country in 2018.

A Reuters report, also said in June last year, that Iranian crude shipments continued to rise in 2023 with higher shipments to China, Syria, and Venezuela. The report quoted consultants, shipping data, and a source familiar with the matter.

A large chunk of Iran’s crude oil goes to China which is the world’s major importer of energy. Several European customers including Germany, Spain, and Bulgaria also imported oil from Iran.

Iran has not released official figures about its oil exports over the past years amid efforts to evade Washington’s illegal sanctions.
