HOUSTON, TEXAS -- (Marketwire) -- 02/01/13 -- Cub Energy Inc. ("Cub" or the "Company") (TSX VENTURE:KUB), a Ukraine-focused upstream oil and gas company, announces the discovery of commercial volumes of natural gas in the Krutogorovskoye-7 ("K-7") exploration well in Ukraine. The K-7 well is operated by KUB-Gas, a partially-owned subsidiary in which Cub has a 30% ownership interest.

The K-7 well commenced drilling in September 2012 and was cased to a total depth ("TD") of 3,206 metres in early November 2012. Wireline logging of the well indicated up to 5 potential gas zones in the Bashkirian and Serpukhovian sands between depths of approximately 2,390 metres and 2,760 metres. A 10 metre section of the Bashkirian B12 zone, from a depth of 2,395 to 2,398 metres and from 2,400 to 2,407 metres, was selected for testing.

The well was flow tested for a period of 14 hours using the various choke sizes listed in the table below and achieved a maximum rate of 5.914 MMcf/d through a 9 mm choke. Average production through the 9 mm choke was 5.896 MMcf/d at an average flowing pressure of 14,435 kPa.

During the test the well was slugging condensate and analysis of well data indicates a calculated rate of 33 barrels of condensate per MMcf of gas.

The well, which has now been shut-in to observe pressures, is expected to be on production in the third quarter of 2013 after the construction of 1.7 kilometres of new pipeline.

Notes to Editor:

Krutogorovskoye is a 1,100 hectare exploration licence granted to KUB-Gas in 2004.
