This paper presents a description and a preliminary evaluation of the Jobo steamflood project, located in eastern Venezuela, from startup in March 1981 through Dec. 1986. The Jobo project consists of a steamdrive at original reservoir pressure conditions (1,300 psia (8.96 MPa)) because an active aquifer supporting this reservoir prevents pressure depletion by primary steam-stimulated production. The primary recovery estimated for this 8.5/sup 0/ API (1.01-g/cm/sup 3/) accumulation of 10% stock-tank original oil in place (OOIP) is expected to increase to above 45% by steamflooding. To date, 36.2% of the project's stock-tank OOIP has been produced, and steam breakthrough is expected to occur during 1988. Production and injection well completions, as well as surface equipment, were evaluated for the future commercial development of this and other extra-heavy reservoirs in Venezuela.
