India's Bharat Petroleum Corp Ltd (BPCL) has purchased its first crude oil cargo from Argentina, acquiring 1 million barrels of Medanito crude for February delivery from Mercuria. This light-sweet crude, similar to U.S. WTI, will be trial-processed at BPCL's refineries, reflecting efforts to diversify its crude sources. Previously, Medanito was delivered to Australia's Geelong refinery.
