I do have some stats which may be very supportive to their technology development.
Asphalt Ridge: one of Utah’s prolific oil sands regions. Over 1.5 billion bbl of proven/probable reserves.
Deposits from surface - 1000 feet.
Richness varies: 100 to 300 bbl/  acre-foot.
Measured Resource: Asphalt
Ridge estimated @ 0.8 billion
bbls underlying 29,000 acres.
