CUB Energy Inc.: M-21 Well Tests 3 MMcf/d, 4 Potential Zones Identified In NM-1 Well & Activity Update

HOUSTON, TEXAS--(Marketwire - June 19, 2012) - CUB Energy Inc. ("CUB", or the "Company") (TSX VENTURE:KUB), an upstream oil and gas company, today provides update information on its Eastern Ukraine activities in the Makeevskoye, North Makeevskoye and Olgovskoye License areas, each of which are operated by KUB-Gas LLC ("KUB-Gas"), a subsidiary in which CUB has a 30% effective ownership interest.

HIGHLIGHTS

• M-21 well tested natural gas at a rate of 3 MMcf/d;
• NM-1 drilled to a depth of 2,500 metres and cased to TD after log and drilling information indicate 4 potential hydrocarbon-bearing zones;
• North Makeevskoye 3D seismic survey acquires 225 square kilometres of new data - processing underway with interpretation to be completed by September;
• O-14 well suspended and being evaluated as a potential candidate for fracture stimulation.

Makeevskoye-21 Testing

The Makeevskoye-21 ("M-21") well was drilled to a total depth ("TD") of 2,210 metres in the first quarter of 2012. Two potential hydrocarbon-bearing zones were identified and the well was cased to TD to enable future testing. The first zone, the R8 zone which correlates with the gas producing zone in the M-19 well, has been perforated and flowed natural gas at a test rate of 3 million cubic feet per day ("MMcf/d") (.9 MMcf/d net to the 30% interest of CUB) on an 8 millimetre choke. The well is expected to be tied-in for commercial production late in Q3 2012. Once tied in, the Company will evaluate testing of the B zone. As a result of the successful testing of the R-8 zone, M-21 well and the consistently high production rate from the Makeevskoye-19 ("M-19") well, the drilling program for 2012 is being revised to bring forward the timing for the drilling of the Makeevskoye-20 ("M-20") well.

North Makeevskoye Exploration Well

The North Makeevskoye-1 ("NM-1") exploration well, which commenced drilling on 5 May 2012, has been drilled to its planned TD of 2,500 metres, wireline logged and cased to TD. Evaluation of both the wireline logs and information obtained during the drilling of the well indicates potential for hydrocarbon accumulation in 4 reservoir units in Bashkirian and Serpukovian aged sediments. Two reservoir units are within a 70 metre thick limestone interval and another appears to be a 30 metre thick sandstone. Production testing of the NM-1 well is expected to take place early in Q3 2012. The drilling rig will start moving to the M-20 location shortly and the M-20 well is expected to spud in mid-July.

North Makeevskoye Seismic

During the second quarter of 2011, KUB-Gas acquired 71 kilometres of new 2D seismic data over the North Makeevskoye Licence. Interpretation of this new data in combination with approximately 275 kilometres of pre-existing 2D seismic data resulted in NM-1 being defined as the first drilling location on this new licence. In the first quarter of this year 225 km² of new 3D seismic data was acquired over the majority of the North Makeevskoye Licence. Processing of the recently acquired 3D seismic data is currently underway and interpretation expected to be completed in Q3 2012.

Olgovskoye-14

The Olgovskoye-14 ("O-14") well was drilled to a TD of 2,800 metres in June and July of 2011 and cased to TD pending further evaluation. Potential hydrocarbon-bearing zones were identified from wireline logging and drilling information. Recent testing of the well indicated low permeability in the reservoir target zones and the well is currently suspended as a potential candidate for fracture stimulation later in 2012. In its initial frac program in the fourth quarter of 2011, KUB-Gas successfully completed the fracture stimulation of two wells, Olgovskoye-6 ("O-6") and Olgovskoye-8 ("O-8"). After being frac'd the O-6 well flowed gas at a rate of 2.3 MMcf/d and the O-8 well flowed gas at a rate of 1.0 MMcf/d, both from previously non-commercial zones.
