OMDA Oil & Gas Notified of Drilling Rig Arrival on Its Shelby Co. Texas Patroon Natural Gas Prospect

Houston--(BUSINESS WIRE)—October 21, 2005

OMDA Oil and Gas, Inc. (OTC.PK:OMOG), an oil and gas production company, through its Chairman, Adam Barnett, was notified today by its operator, Texas Land and Producing Co, (TLP) that its long awaited drilling rig and contractor, Fran Drilling, has arrived on location to begin drilling its approximate 6,000 foot initial test on its Patroon natural gas prospect in Shelby County Texas. This initial well on the nine to ten well 800-acre lease is the Patroon #1. OMDA has a 15% working interest in this well and all subsequent wells on the lease. The well will be drilled to approximately 6,000 ft and is expected to take a day to "Rig Up" and 12 to 14 days to reach total depth and to be logged. Surface casing will be set to approximately 1,600 ft. at which time mud logging will begin. While the primary target zone is the Mooringsport which is expected to be found between the 5,000 to 5,500 foot level, the mud logging will be used to sample a few secondary zones.

This exciting lower risk 6,000 ft wildcat well is a 1,000ft. offset to a 1946 Humble Oil wildcat that was tested and for a short period of time produced from one of two Mooringsport zones. The lower zone at 5272'-5290' tested at 1.758 million cubic feet of gas per day (cf/d) and 135 barrels of oil per day (bopd). Since the nearest gas line was a hundred miles away at that time, this zone was never produced. The next Mooringsport up the hole at 5,164'-5192' tested at 1.204 million cf/d and 109 bopd and was completed and produced for approximately 18 months and totaled around 15,000 barrels of oil while flaring the gas. The Humble well was subsequently abandoned due to the very low price of oil and lack of gas value in 1950. TLP acquired this acreage in 1999 when the price of oil was around $20 bbl and gas prices were around $2.00 mcf. Drilling at that time was almost non-existent in this now hot area. If this well proves to be successful, 8-9 additional wells could be drilled on the existing acreage. TLP has informed the company that if this well comes in as hoped for, it is likely that testing results will be "tight holed" for a few weeks as additional acreage is acquired.

A third party Petroleum Reservoir Engineering report by TEC estimates recoverable gas reserves per 80 ac. unit of 1.226 Billion Cubic Feet and oil reserves of 36,000 barrels. If these estimates prove correct, future net revenues could approach $18-20 million to the 8/8 ths, per 80 acre unit or as much as $180-200 million on the current 800 acres. These estimates are based on current oil and gas prices.

Detailed information on the Patroon project including descriptions, maps, charts, old drilling logs on the Humble well and a copy of the third party reservoir engineering report can be found on the company's website at http://www.omogoil.com/projects.html.

Adam Barnett, Chairman, stated, "After what seems like an eternity to get a rig on this location, I could not be happier to see us begin drilling this potentially huge primarily natural gas well. The timing could not be more perfect since natural gas prices have more than doubled over the past few months and are now approaching record highs of $14 mcf. While the cost to OMDA to drill this well is not cheap and there are some risks involved in this project, the risk/reward ratio has become almost astounding due to the current price of Oil and Gas."
