A steamflood experiment was conducted in the Northwest Asphalt Ridge deposit located near Vernal, Utah. Steam was injected into the center well of two concentric inverted five spot patterns. The pattern area contained a 12/degree/API bitumen with a viscosity greater than 10/sup 6/ centipoise at reservoir conditions. The average oil saturation was 78.9 percent of the pore volume. During the 160 days of operation, 65,700 barrels of water equivalent steam were injected at 360 to 530 psig and 180 to 650 bpd. Total production during the test amounted to 1,150 barrels of oil and 6,250 barrels of water. 4 refs.
