U.S. ENERGY CORP. ANNOUNCES INITIAL PRODUCTION RATE OF APPROXIMATELY 3,394 BOE/D FROM THE WILLISTON 25-36 #1H WELL

RIVERTON, Wyoming – December 14, 2009 – U.S. Energy Corp. (NASDAQ Capital Market: USEG) (“USE” or the “Company”), a natural resources exploration and development company with interests in oil and gas, molybdenum, geothermal, and real estate assets, today announced the initial production rate from its Williston 25-36 #1H well and provided an operations update regarding its Williston Basin drilling program with Brigham Exploration Company (NASDAQ: BEXP) ("Brigham" or "BEXP").

The Williston 25-36 #1H well, which is operated by Brigham Exploration Company, produced approximately 2,769 barrels of oil and 3.75 MMCF of natural gas per day or 3,394 BOE/D during an early 24 hour flow back period. The well was completed with swell packers and 32 fracture stimulation stages. To USE’s knowledge, this completion is the highest number of fracture stimulation stages ever attempted in the Williston Basin. U.S. Energy’s initial working interest in this well is approximately 65% (~51% net revenue interest). Oil sales from this well have commenced, and natural gas sales will commence upon connection to a gathering system, which is estimated to take approximately 90-120 days.

Williston Basin - Bakken Drilling Program

Completion work is currently underway on the State 36-1 #1H well, which is the sixth well to be drilled under the previously announced Drilling Participation Agreement with Brigham. The well is being completed with swell packers and 30 fracture stimulation stages. USE’s initial working interest in this well is approximately 28% (~22% net revenue interest), and Brigham has informed USE that it expects to complete and test the well for production before year end.

On November 30, 2009, and subsequent to providing the initial production rate on the fourth well, the Strand 16-9 #1H, Brigham notified USE pursuant to the terms of the Drilling Participation Agreement that the Company was required to give notice to Brigham whether the Company would elect to participate in the second group of four wells, and that Brigham was electing to have the maximum 50% of the working interest available to Brigham in the second group of wells. On December 2, 2009, USE notified Brigham of its election to participate in these four wells for the remaining 50% working interest available to Brigham in these wells.

The Jack Erickson 6-31 #1H well (~21% initial working interest) will be the seventh well drilled under the Drilling Participation Agreement with Brigham. The well is expected to be spud in the next several days and it is anticipated that it will be completed in approximately 60 days.

About U.S. Energy Corp.

U.S. Energy Corp. is a diversified natural resource company with interests in oil and gas, molybdenum, geothermal and real estate assets. The Company is headquartered in Riverton, Wyoming, and its common stock is listed on The NASDAQ Capital Market under the symbol “USEG”.

Note Regarding BOE

In this press release, BOEs are derived by converting gas to oil in the ratio of one barrel of oil to six thousand cubic feet of gas (1 bbl:6 Mcf). Barrel of oil equivalent ("BOE") amounts may be misleading, particularly if used in isolation. A BOE conversion ratio of 1 bbl of oil to 6 Mcf of natural gas is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value of equivalency at the well head.

Note:

Outstanding third party elections may result in a change to USEG’s working interest and net revenue interest on a well-by-well basis.
