GeoResources, Inc., (Nasdaq:GEOI), today provided an operations update.

AUSTIN CHALK

GeoResources continues its successful exploitation of the Austin Chalk Formation in Giddings Field, Grimes and Montgomery Counties, Texas. The Longstreet Unit #1-H, which is its seventh dual lateral well, has been drilled, completed and placed on production. The well was drilled to a vertical depth of over 14,487 feet, with a horizontal leg of 7,030 feet. An additional horizontal leg was kicked off from a point approximately 650 feet into the first lateral and drilled 5,973 feet. The well had an initial rate of approximately 30 MMCFD, being the highest initial rate of any of the wells drilled by the Company to date and has averaged in excess of 23 MMCPFD during the first full week of production. The Company has drilled 13 Austin Chalk wells to date and achieved a 100% success rate. GeoResources is the operator of all of these wells and holds a direct working interest ranging from approximately 34% to 37% and has an additional working interest of approximately 15% through its affiliated partnership. The Company intends to spud the next well in the fourth quarter. The delay is a direct result of routine land, access and related issues. Although these wells are highly economic even at prevailing prices, a secondary consideration is the current gas market. Our present inventory includes 15 proved undeveloped and probable locations within the Giddings Field.

BAKKEN SHALE

The Company holds a proportionate 10% - 15.5% working interest in approximately 100,000 net acres in the Bakken shale trend of the Williston Basin. Approximately 59,000 acres are located in Mountrail County, with the remainder located in adjacent counties. To date, the Company has realized a 100% success rate with 24 successful wells drilled by the joint venture operator. In addition, the Company owns minor working interests in over 120 wells within the Bakken/Three Forks play. These wells have provided invaluable information related to the geology, drilling and completion procedures and development economics. The joint venture continues to acquire acreage in this expanding play and has recently added two additional rigs to the drilling program for a total of three drilling rigs, and may occasionally run a fourth drilling rig. With continuous drilling by three to four rigs we expect to participate in approximately 60 joint venture wells over the next 18 months, exclusive of the participation in numerous minor interest wells. The Company intends to report joint venture wells and other wells where its interests are meaningful, but will generally not report minor interest non-operated wells.

Recent wells are as follows:

Completed well costs, with production facilities for single lateral wells drilled on 640 acre units, have decreased significantly due to reductions in service company costs, and improvements in drilling and completion techniques. The joint venture operator has completed recent wells, including production facilities, for under $3.5 million. The economics of drilling on 640 spacing units are attractive and allows us to “prove-up” and place acreage on production under an expedited schedule. Further, where we drill two or more wells off a single pad, additional vertical well bores may allow for further cost-effective development from in-fill locations or deeper horizontal drilling. However, we are considering 1,280 acre spacing units and have numerous locations which may result in or require such spacing. Certain of these larger units could be spud before year end.

Other Drilling

The Rose 1-19, located in Carter County, Oklahoma, has been drilled and completed as an oil well and is in the process of being completed in the Simpson Formation with several additional shallower zones to be added or recompleted over time that are behind pipe. The Company expects the Rose 1-19 to commence production during the third quarter of 2009. The Company has a 10.0% working interest in the property.

The Romero #1, located in Vermillion Parish, Louisiana, has been drilled and completed as a gas well at an estimated true vertical depth of 15,860 feet and has been completed in the Camerina Sand Formation and should commence producing during the third quarter of 2009. The Company has a 12.5% working interest in the property.

Comments

Frank A. Lodzinski, Chief Executive Officer of GeoResources, said, “Our drilling programs continue to deliver positive results. Our Austin Chalk development continues to deliver significant production and our inventory currently includes 15 locations where we will have in excess of a 50% working interest, including our partnership interest. We have interests in approximately 67,000 acres, a majority of which is held by production. Much of the acreage is held by production and prospective for the Eagle Ford Shale, Buda and Georgetown formations. The Bakken shale development play has been recently expanded and provides a continuous opportunity to add reserves and production. We have interests in approximately 100,000 acres, with over 59,000 acres located in the heart of the play in Mountrail County. We continue to seek attractive acreage additions in both of these successful core areas. Our strong cash flows, earnings and liquidity provide adequate funding for our capital programs.”
