Update on Ud-2 well

Frontera Resources Corporation (AIM: FRR), the European focused oil and gas exploration and production company, is pleased to announce that workover operation of the Ud-2 well has been successfully completed as planned. Further to the announcement of 21 September 2017, the bridge plug has been set at 3326m, pressure test performed and, as previously announced, the Company will now commence extended testing of three target gas bearing intervals of Oligocene-aged, Lower Miocene-aged and Middle Miocene-aged reservoirs, located between 2620m - 3320m. 

The service company, which has been contracted to perforate gas bearing intervals of Ud-2 well, will now mobilise on site.

The final technical design of the 18km gas pipeline connecting the Ud-2 well with Mtsare Khevi gas processing facility (which is connected to Georgia's natural gas distribution grid) is being completed and the pipeline right of way is being secured.

Zaza Mamulaishvili, President and Chief Executive Officer, commented:

"It is a very important milestone to complete workover operation of the Ud-2 well in time and within budget. We are very excited that this successful operation made three gas-bearing intervals available for proper testing. The Middle Miocene-aged Gareji reservoir is a very well known, prolific oil and gas-bearing formation in the area, the Oligocene and Lower Miocene-aged Maykop reservoir is a world class rock source for a number of large oil and gas fields situated within the Black Sea and Caspian Sea areas, one of which is the giant Shah Deniz gas field offshore Caspian. 

"Successful testing of the Ud-2 well, situated inside the 950 km2 Mtsare Khevi Gas Complex, will help prove the tremendous gas potential of Block 12 in Georgia. According to Netherland Sewell & Associates' estimates, the area contains 8.3 Trillion Cubic Feet of Gas in Place of which 5.8 Trillion Cubic Feet is considered recoverable.

"I look forward to keeping shareholders updated on our progress."
