It is very light oil and condensate, even higher that what has been produced from the nearby Alpine and Fjord fields.

USGS report reduces estimate of oil in petroleum reserve

And yet, the agency scientist who published the new estimates cautioned against overreacting. He stressed on Tuesday that the reserve does hold some decent-sized accumulations of oil — particularly in the northeast, near Teshekpuk Lake — and its potential for gas is “just phenomenal.”

Some geologists in Alaska are having a hard time believing the NPRA contains 90 percent less oil than the Geological Survey estimated just eight years ago.
“It makes NPRA — the bulk of NPRA — very questionable with regard to oil,” said David Hite, an Alaska petroleum geologist and private consultant.
...
Hite and other geologists in Alaska said they need to look more carefully at the agency’s findings before they feel confident accepting it.
“It seems somewhat controversial to me,” said Dick Garrard, geoscience manager for FEX, the Alaska subsidiary of a Canadian energy firm called Talisman.

The new report, however, shows that one of the most promising places for oil exploration in NPRA is in one of its most environmentally sensitive areas, near Teshekpuk Lake.
But environmentalists have fought in court to protect the area from development, citing its importance for migratory birds.
I’m sure you’re aware that light condensate has only 60% of the BTUs of proper crude.
