TransAtlantic Petroleum Ltd., Hamilton, Bermuda, (TSX: TNP) (AMEX: TAT) has reported an operational update on its Turkish exploration and production activities.

Southeastern Turkey - License 4174 (Molla)

On License 4174, the company completed the Goksu-1 well as a new field discovery in the Mardin group at approximately 5,500 feet (approximately 1,650 meters). The well was completed with a light acid skin stimulation and had an initial flow rate of 340 barrels of oil per day with a 20% water cut on restricted choke. Existing 2D seismic data indicates the Goksu structure may be approximately 2,500 acres (approximately 10 square kilometers) in extent. Oil samples recovered from the well indicate 23 degrees API gravity. The Goksu-1 well was originally drilled in 2010 to test the Bedinan sands, which was unsuccessful, and the Silurian-aged Dadas shale, which tested natural gas and condensate at non-commercial rates from a vertical completion. In light of the discovery, the Company is evaluating additional development on License 4174, in which the Company is the operator and 100% working interest owner.

Southeastern Turkey - License 3118 (Arpatepe)

On License 3118, immediately to the south of License 4174, the company recently participated in the drilling of two exploration wells. The Kocahoyuk-1 exploration well encountered the target Bedinan sands formation low to the prognosis and was plugged and abandoned. The company owns a 50% working interest in License 3118, and the operator of the license, Aladdin Middle East Ltd. (AME), paid all drilling costs for the well.

The Arpatepe-4 exploration well encountered the target Bedinan sands formation, and the company is currently setting casing in anticipation of testing the well. The company paid all drilling costs for the Arpatepe-4 well.

The company and AME expect to drill at least two more development wells and one more exploration well on License 3118 this year, with AME funding all of the drilling costs of the two development wells and the company funding all of the drilling costs of the exploration well.

Northwestern Turkey - Thrace Basin

Following evaluation of physical and geological conditions, the company and its license partners have resumed the pilot fracture stimulation program on certain of the shallow natural gas wells acquired when the company purchased Thrace Basin Natural Gas (Turkiye) Corporation. Following the completion of the program, the company plans to mobilize a fracture stimulation crew to conduct operations at the company's Selmo oil field in southeastern Turkey.

In addition, the company has mobilized its Rig 8 to drill the company's first new drill deep test in the Thrace Basin. The company expects to test the Mezarde sands at approximately 7,500 to 10,500 feet (approximately 2,300 to 3,200 meters), located under the shallower producing Alpullu gas field.
