The Orinoco Crude is so thick it must be thinned with Naphtha for shipment and ease of processing.  At one point Venezuela was buying the Naphtha, thinning their crude, and shipping the blend to meet their contact obligations.  They were getting less for the blend than they paid for the Naphtha it contained.  They were selling oil and losing money on every barrel.  Losing money selling oil is a phenomenal achievement.
