With Iran poised to resume usual business ties with the world under a historic nuclear deal, Tehran is set to target India, Asia's fastest-growing major oil market, and old partners in Europe with hundreds of thousands of barrels of its crude.

Iran expects the U.N. nuclear watchdog to confirm on Friday it has curtailed its nuclear program, paving the way for the unfreezing of billions of dollars of assets and an end to bans that have crippled its oil exports.

Tehran plans to lift exports by 500,000 barrels per day (bpd) post-sanctions and gradually raise shipments by the same amount again, adding to a glut of global oil and likely putting more pressure on oil prices which have already dropped 70 percent since 2014 to around $30 per barrel.
