Venezuela's PDVSA sold three cargoes of intermediate fuel oil with 380 CST and one 3% sulfur fuel oil cargo to PetroChina for June, a source familiar with PDVSA's operations said Friday.

The first intermediate fuel oil cargo is loading June 13-15 on the tanker Newton, destined for China. The second cargo is loading June 19-21 on the tanker Maxim, also with China as its destination, and the third is loading June 28-30 on an unknown tanker for delivery to Singapore.

The 3%S fuel oil cargo is scheduled to load June 26-28 on an unknown tanker and is also being delivered to Singapore, the source said.

All the cargoes are 2 million barrels and will load either at Freeport, Bahamas, or Bonaire, in the southern Caribbean, the source said. PDVSA has storage at these ports.

Two of the intermediate fuel oil cargoes will load in Freeport; the other intermediate cargo and the 3% sulfur fuel oil will load in Bonaire.

PetroChina traditionally buys several million barrels of 3%S fuel oil from PDVSA, destined for Singapore or China, sources said.

PDVSA in May exported three cargoes of intermediate fuel oil with 380 CST, two to Singapore and one to China, according to a previous program. One 3%S fuel oil cargo was delivered to Singapore, the program said.
