HOUSTON, TEXAS--(Marketwired - May 15, 2014) - Cub Energy Inc. ("Cub", or the "Company") (TSX VENTURE:KUB) announces the Rusko-Komarovske-21 ("RK-21") development well, on the Rusko-Komarovske ("RK") licence, in western Ukraine has tested gas at a maximum rate flow rate of 2.6 million cubic feet per day ("MMcf/d") through a 12-millimetre choke. Cub is the owner and operator of the RK-21 well and has a 100% working interest in the RK licence.

RK-21 Well

The RK-21 well location was identified by 3-D seismic acquired by Cub in 2013 and is the second well drilled by Cub on the RK licence. The RK-21 spud in mid-March 2014 and multiple potential gas bearing zones were encountered in the targeted middle Miocene Dorobratovskaya and Badenian sands locally referred to as the D-1 through D-5 and B-1 through B-5 sands.

The D-3 sands were perforated over a four-metre interval between 1,111 metres and 1,114 metres then subsequently flow tested through various choke sizes. The well achieved a maximum stabilised natural gas flow rate of 2.6 MMcf/d through a 12-millimetre choke with a flowing tubing pressure of 545 pound-force per square inch ("psi") and a shut-in casing pressure of 672 psi.

Mikhail Afendikov, Chief Executive Officer of Cub Energy, commented, "We are excited about the success of this 100-percent working interest well and our entire 2014 drilling program. This success is a testament to our team's hard work and efforts. Our operations and this year's work program continue uninterrupted and we move forward with our efforts of increasing the Company's reserves and production profile from our assets in the black-sea region."

The Company expects to have the RK-21 on production by May 16, 2014 and is currently evaluating additional completions options in the remaining zones identified. The Esta Well Services rig used to drill the RK-21 is now being mobilised to the RK-1 location where Cub will re-enter the well for a test of the deeper Mesozoic sands that logs show to be potentially gas charged.

Oil and Gas Equivalents

A barrel of oil equivalent ("boe") or units of natural gas equivalents ("Mcfe") is calculated using the conversion factor of 6 Mcf (thousand cubic feet) of natural gas being equivalent to one barrel of oil. A boe conversion ratio of 6 Mcf: 1 bbl (barrel) or an Mcfe conversion of 1bbl: 6 Mcf is, based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead and is not based on either energy content or current prices. While the boe ratio is useful for comparative measures, it does not accurately reflect individual product values and might be misleading, particularly if used in isolation. As well, given that the value ratio, based on the current price of crude oil to natural gas, is significantly different from the 6:1 energy equivalency ratio, using a 6:1 conversion ratio may be misleading as an indication of value.
