The quality problem is very much related to the country’s economic crisis. Without cash, PDVSA is struggling to obtain the proper chemicals to treat its oil, or pay for equipment and upkeep to maintain quality. As a result, PDVSA has had to shut down operations, or throttle back on production. “We’re refitting chemical injection points, recouping pumps and storage tanks,” one PDVSA worker told Reuters. “But without chemicals, we can’t do anything.”
The oil company has been shipping crude that is apparently causing problems for refiners around the world. According to Reuters, that has led to complaints and even cancellations of purchases. Phillips 66, a U.S. refiner, cancelled at least eight cargoes in the first half of the year due to inferior quality. It also demanded discounts for other shipments. Refiners in India and China have also lodged complaints.
The sales cancellation poses a serious financial threat to a company and country already wallowing in a horrific economic crisis. For example, the cancelled shipments were carrying oil representing $200 million in value, according to Reuters estimates. PDVSA is the only lifeline for the Venezuelan state, so reports that the one source of revenue keeping the country somewhat afloat is not only declining but is now exhibiting declining quality is alarming.
