Artesian Aquifer, New Fork Tongue of the Wasatch Formation, Northern Green River Basin.
Wyo Geol Assoc Guidebook 25th Field Conf PP 201-206 :201-206
An artesian aquifer is found in the New Fork tongue of the Wasatch Formation in the northern Green River Basin. Overlying the aquifer is the Wilkins Peak member of the Green River Formation which contains potentially developable oil shales. The aquifer contains substantial amounts of water available for possible use in an oil- shale industry. Flow rates as high as 500 gallons per minute are presently being produced from abandoned oil test wells. The water, containing sodium carbonate and sodium bicarbonate as the principal dissolved solids, is not classed as potable owing to excessive amounts of fluoride and total dissolved solids. Recharge for the aquifer is found to the north where the new fork tongue becomes arkosic. The area of known artesian production is about 500 square miles. An additional 700 square miles may contain artesian water from the same source.
