HOUSTON, Feb 20 (Reuters) - Colombian state-run Ecopetrol launched several tenders to buy up to 930,000 barrels of diluent naphtha, up to 300,000 barrels of ultra low-sulfur diesel (ULSD) and 105,000-110,000 barrels of jet fuel for March, according to invitations seen by Reuters.
The oil company has increased puschases of finished fuels this year, while planning the upgrade of its 80,000 barrel per day (bpd) Cartagena refinery to duplicate its capacity.
The first tender launched by Ecopetrol is to buy three 290,000-300,000 barrel cargoes of diluent naphtha to be received on March 17-31 at Pozos Colorados port. The company will received offers until February 24.
The second one, launched by Ecopetrol and the Cartagena refinery, is to purchase 1-2 ULSD cargoes of 148,000-150,000 barrels each, with maximum 30 parts per million sulfur.
These cargoes can be delivered in the U.S. Gulf Coast or any Caribbean port on March 17-19 or can be sent to Mamonal, Colombia, on March 22-30, the company said.
With the last tender, Ecopetrol and Cartagena will buy one 105,000-110,000 barrel cargo of jet fuel for delivery on March 16-18 at Mamonal.
The companies will receive bids until February 21 and they must be indexed to jet fuel prices from the U.S. Gulf Coast. (Reporting by Marianna Parraga; editing by Terry Wade)
