Nostrum Oil & Gas: Proven Reserve Replacements Ratio at 65%

Nostrum Oil & Gas PLC, an independent oil and gas company engaging in the production, development and exploration of oil and gas in the pre-Caspian Basin, today announces the results of the independent reserves audit of its licenses in north-western Kazakhstan as at 31 December 2014.

Highlights from the 2014 Ryder Scott Reserves report:

• Proved reserves (1P) at 192.2mm boe

• Production of approximately 21mm boe since the last report, with a proven reserve replacement ratio of over 65%

• Proved + Probable reserves (2P) remained above 550mm boe at 571.1mm boe (2013: 582mm boe). The reduction was primarily a result of production exceeding Proved + Probable reserves (2P) growth.

• The 3 additional licenses’ reserves have remained unchanged at 98.2mm boe

Nostrum’s CEO, Kai-Uwe Kessel stated:

“We are very pleased that our independent auditors, Ryder Scott, have confirmed Nostrum’s existing strong reserve base both at the Chinarevskoye field and the additional licenses acquired in 2013. The steady production of approximately 45,000 boe per day since August 2013 has been largely compensated by the conversion of further reserves into the Proven category at Chinarevskoye. The stability of our reserve base allows us to focus on delivering GTU3 in the second half of 2016, and doubling our processing capacity.”
