Cub Energy Inc.: Makeevskoye-20 Well Cased to Total Depth

HOUSTON, TEXAS--(Marketwire - Aug. 6, 2012) - Cub Energy Inc. ("Cub", or the "Company") (TSX VENTURE:KUB), reports the Makeevskoye-20 ("M-20") well in Ukraine has been cased to total depth ("TD"). The well is operated by KUB-Gas LLC ("KUB-Gas"), a subsidiary in which Cub has a 30% ownership interest.

Makeevskoye-20

The M-20 development well was drilled to a TD of 2,000 metres using the K-200 drilling rig owned by KUB-Gas. The primary objective of M-20 was to evaluate the R8 sands at a depth of approximately 1,450 metres and further develop the Makeevskoye R8 pool originally discovered in the Makeevskoye-19 ("M-19") well drilled in the second half of 2010 and further developed by the Makeevskoye-21 ("M-21") well drilled in the second quarter 2012. The top of the R-8 Zone in the M-20 well is approximately 20 metres higher than in the M-19 and well and 36 metres higher than in the M-21 well. A significant increase in gas in the drilling mud was noted when the R-8 zone was penetrated during the drilling operation. Wireline logs indicate that the zone is 18.5 metres thick, has an average porosity of more than 25% and appears to be completely gas charged.

The M-19 well, located approximately 1 kilometre to the west of the M-20 location, commenced production from the R8 zone in July 2011 at an initial rate in excess of 5.5 million cubic feet per day ("MMcf/d") (1.65 MMcf/d net to Cub). The M-21 well, located approximately 2 kilometres west of the M-20 location, was tied in for commercial production at a rate of 1.7MMcf/d (.5MMcf/d net to Cub) at the beginning of August. The KUB-Gas owned and operated drilling rig is now scheduled to move from the M-20 location to the Krutogorovskoye-7 ("K-7") location in late August 2012. The K-7 well will be drilled to a TD of 3058 metres to evaluate the potential of Moscovian and Bashkirian zones in a new structure defined by seismic.

Mikhail Afendikov, Chairman and Chief Executive Officer, stated:

"The M-20 well, with its further development of the R-8 Pool, reflects our on-going commitment to increasing the company's production and revenue by focusing on low-risk development of our proven and underexploited assets. We are progressing our robust investment plans in Ukraine and continue to grow the Company through the acquisition of large undeveloped license areas contiguous with current production and developing them through the combination of seismic, western technology, modern completion practices and local expertise."
