The first Laramie Energy Technology Center steamflood experiment in Utah tar sand, LETC TS-IS, was conducted in the N. Asphalt Ridge Deposit located near Vernal, Utah. Following completion of construction in April 1980, steam injection was initiated in the center well of 2 concentric inverted 5-spot patterns. The zone chosen for the experiment was a 45-ft (14-m) thick sandstone in the Rimrock member of the Mesaverde Formation. The pattern area was 0.25 acres (1012 sq/m) and contained a 12-1/4 API (986 kg/cu m) bitumen with a viscosity greater than 106 cp (103 pa/sec) at reservoir conditions. The average oil saturation was 78.9% of the pore volume. During the 160 days of operation, 65,700 bbl (10.4 dam3) of water equivalent steam was injected at 360 to 530 psig (2.5 to 3.7 mpa) and 180 to 650 bpd (29 to 103 cu m/day). Total production during the test amounted to 1150 bbl (183 cu m) of oil and 6250 bbl (994 cu m) of water.
