El Furrial field, located in the north of Monagas state, was discovered in 1986. It originally contained about 7 billion STOIIP. The field is approximately 13 km along strike and 7 km wide. It produces from two reservoirs identified as the Naricual and Los Jabillos Formations. The gross thickness of the two reservoirs is about 2500 ft. The oil composition in the Furrial Field changes rapidly with depth from that of a conventional oil (28 °API) at the top of the formation to that of an immovable tar mat, principally as a result of an increasing alphaltene content of the crude.Using such a line of applications had permitted to get a very integrated model and to be secure of the existence of a very close link between the resulting static and dynamic models.
