In the latest sign of recovering oil flows in the Persian Gulf, Qatar inked a deal with a Taiwanese refiner for the sale of a cargo of Al-Shaheen crude, Bloomberg reported today, citing unnamed trading sources. The deal follows the sale of Marine and Land Qatari crude to an Indian refiner last week, the sources also told the publication. Bloomberg also reported that ship-tracking data showed a Gfreek-owned supertanker currently loading at the Al-Shaheen floating storage terminal.
