GeoResources, Inc. Provides Operations Update

BAKKEN SHALE

The Company holds a proportionate 10% - 18% working interest in approximately 110,000 net acres in the Bakken Shale trend of the Williston Basin. Approximately 63,000 acres are located in Mountrail County, North Dakota, with the remainder located in adjacent counties. To date, the Company has realized a 100% success rate with 34 successful wells drilled by its joint venture operator. In addition, the Company owns minor working interests in more than 125 wells within the Bakken/Three Forks play. These wells have provided valuable information related to the development economics, geology and drilling and completion procedures with multiple operators at different locations within the basin. Our joint venture continues to acquire acreage in this expanding play and is currently running three drilling rigs and may occasionally run a fourth drilling rig.

The following table and comments provide an overview of our current and expected activities. The drilling schedule is subject to change. Please refer to prior news releases for prior activity. The Company reports joint venture and other wells where its interests are meaningful, but generally does not report numerous minor interest wells. With the significant acreage acquisition in May 2009 and subsequent acreage additions, the pace of activity has increased and we expect to participate in an estimated 60 joint venture wells over the next 18 months, exclusive of the participation in numerous minor interest wells.

Two additional wells with a 5% and 8% working interest are scheduled in the 4^th quarter. In addition, 13 wells are currently scheduled in the 1^st quarter of 2010 where the Company expects to have working interests in the 5% to 10% range; however, certain wells may be deferred in favor of higher working interest wells.

Completed well costs, including surface equipment and production facilities for single lateral wells drilled on 640 acre units range from approximately $3.0 to $3.5 million. Initial production rates have continued to move upward as the number of frac stages increase. Our recent wells have had 18 frac stages per well.

The majority of our wells has been and is expected to be drilled on 640 acre spacing units. In our view, the economics are attractive and acreage can be “proved up” and placed on production on an expedited basis. However, we are scheduling 1,280 acre (and some larger) spacing units and have numerous locations which may result in or require such larger spacing units.

AUSTIN CHALK

The Company has re-started its successful exploitation of the Austin Chalk Formation in Giddings Field, in Grimes County, Texas. The Hutto Unit #1-H, which is a planned 7,800’ single lateral location, did spud on November 6, 2009. GeoResources is the operator and has a 52% working interest in this field. This location and our next two or three locations will be on the northwest side of our acreage block where we expect the reserves to be more “oily” and result in about 50% oil and liquids. To date, the Company has drilled 13 Austin Chalk wells and achieved a 100% success rate. Our present inventory includes 22 proved undeveloped and probable locations within the Giddings Field. Our working interest varies from 37% to 53%. At present, we expect to sequentially drill all locations with a single drilling rig, but we may accelerate development pending continued success and commodity prices.

MONTANA

In December, the Company will participate in the drilling of the Anderson 1-32R well located in Richland County, Montana. This well will be a replacement of the Anderson 1-32 which was a Red River producer that had previously been plugged due to a mechanical failure. At the time of the failure, the Anderson 1-32 was producing approximately 55 Bopd and had produced in excess of 580 Mbo and 385 Mmcf. The operator estimates the well will spud on November 18, 2009 with an expected total depth of 12,600 feet. The Company has an 18.65% working interest in this replacement well.

BANK CREDIT FACILITY UPDATE

The Company also announced that the borrowing base on its $250 million bank credit agreement has been increased to $145 million. In connection therewith, on July 13, 2009, the Company entered into a Second Amended and Restated Credit Agreement with a term extending to October 16, 2012. The borrowing base of the facility was $135 million, subject to redetermination on November 1 and May 1 of each year. The participating banks include: Wachovia Bank, Comerica Bank, BBVA Compass, U.S. Bank, Frost Bank, Bank of Texas and Natixis.

Comments

Frank A. Lodzinski, Chief Executive Officer of GeoResources, said, “We have re-started our Austin Chalk drilling program after a suspension due to land matters and commodity prices, and expect these activities to deliver production and reserve growth as they have in the past. Our current development inventory includes at least 22 locations where we have working interests ranging from 37% -53%. Our acreage position exceeds 68,000 acres, a majority of which is held by production and is prospective for the shallow Yegua and for the Eagle Ford Shale, Buda and Georgetown Formations. We will attempt to continue to expand our acreage position through direct lease acquisition, asset and corporate acquisitions and farm-ins. Our Bakken program continues to roll forward with positive results and we continue to seek attractive acreage additions in the Williston Basin. Finally, we are pleased to report another increase in our borrowing base. Our strong cash flows, earnings, and liquidity provide adequate funding for our capital programs.”
