Resumen del autor, extraido del trabajo. Venezuela has the largest reserves of heavy oil in the World. Currently heavy oil is produced in Venezuela by cold and thermal methods. This paper describes efforts carried out in PDVSA on understanding the foamy crude behaviour, which is present in some of our heavy crude reserves. This foamy behaviour significantly affects the recovery factor and the exploitation scheme. The other topic addressed is results obtained in-situ upgrading (under reservoir conditions) of heavy crudes. Preliminary results yield an improvement of 8 API degrees. Special attention is given to the Orinoco Oil Belt, a place where the role of technology developments has greatly direct the heavy oil exploitation. v. 2, p. 242 CONGTP Izquierdo, Alejandro 9602 Vallejo, Carlos 9603 Kamp, Arjan 9604 World Petroleum Congress (16th. : 2000 jun. 11-15 : Calgary, Alberta, Canada) 34 Vallejo, Carlos 9603 Kamp, Arjan 9604 Izquierdo, Alejandro 9602 133459 133459 0 0 0 0 204378 BAAB BAAB CD W938 1 0013960 2026-03-04 200005923 0 CD W938 1 0013960 200005923 2026-03-04 14:03:17 2026-03-04 ARCHIVO
