Iran, the world’s fourth biggest oil exporter, offered the blocks for oil and gas exploration at a meeting in Vienna.
The Islamic Republic, which analysts say needs foreign technology to improve production in its fields, had said it hoped to attract international investment of at least 460 million euros ($599 million) in the blocks.
“The 17 new blocks that have been presented in the recent Vienna meeting have been welcomed by 90 foreign companies for investment,” the head of the National Iranian Oil Company (NIOC), Gholamhossein Nozari, was quoted as saying by state radio.
The United States has frowned on deals that Asian and European oil companies have signed with Iran as it seeks to punish Tehran for working on nuclear enrichment, which Washington says is aimed at producing an atomic bomb.
Analysts say international companies have delayed investment decisions as they wait to see how the situation develops.
A U.S. official has said Washington would examine a multi-billion dollar preliminary deal signed in January by Royal Dutch Shell and Spain’s Repsol to develop gas fields and export facilities in Iran.
The U.S. has sanctions in place to punish foreign companies that invest more than $20 million a year in Iran’s energy sectory, but has never enforced them.
Nozari has previously said NIOC was aiming to boost its crude output capacity to 5.3 million barrels per day by 2015 from around 4.2 million bpd now.
