Fairweather Geophysical LLC will do a 1,000 square mile gravity survey for Forest Oil Corp. in the Susitna River Valley this winter.
Fairweather told the state that the survey will be done from snow machines between Jan. 15 and April 30 in townships 19 north to 25 north, ranges 5 west to 11 west, Seward Meridian.
Fairweather will acquire gravity data along north-south lines spaced a mile apart using 10 pound hand-held gravity meters.
Gary Carlson, senior vice president of Forest's Alaska business unit, told PNA in October that the company has applied for exploration licenses in the Susitna area.
