Cub Energy Inc. Reaches Record Production with Makeevskoye-16 Well Tie-In

HOUSTON, TEXAS--(Marketwired - June 5, 2013) - Cub Energy Inc. ("Cub" or the "Company") (TSX VENTURE:KUB), a Black Sea region-focused upstream oil and gas company, today announced that it has reached record production levels with the tie-in of the Makeevskoye-16 ("M-16") well in Eastern Ukraine. The well is operated by KUB-Gas LLC ("KUB-Gas"), a partially-owned subsidiary in which Cub has a 30% effective ownership interest.

The M-16 well commenced production from the S5 zone in late May and produced an average of 2.71 million cubic feet per day ("MMcf/d") (0.81 MMcf/d net) of natural gas during the first four days after tie-in. Gross natural gas production for KUB-Gas during that period increased to approximately 28.5 MMcf/d (8.55 MMcf/d net to Cub) or 4,750 barrels of oil equivalent per day ("Boe/d") (1,425 Boe/d net to Cub).

Makeevskoye-16

The M-16 well commenced drilling in early August and was cased to a total depth ("TD") of 4,300 metres in December 2012. In April 2013, the well tested gas from the S5 zone at a maximum rate of more than 4.3 MMcf/d. The M-16 was the first well drilled by the Company through the entire Serpukhovian aged section that is overlain by the Moscovian and Bashkirian aged sediments, which host the commercial gas reservoirs found previously in the immediate area.

Gas processing facility upgrade

After the tie-in of M-16, the KUB-Gas gas processing facility at Makeevskoye (the "Makeevskoye Facility"), which handles the gas produced in both the Makeevskoye and Olgovskoye field areas, is near its maximum capacity with total throughput of more than 28 MMcf/d. As a result, KUB-Gas is currently working on an expansion of the gas processing capacity of the Makeevskoye Facility to accommodate additional production from the Olgovskoye Licence and from continued development of the gas reservoirs discovered by the M-16 well.

The facility upgrade is scheduled to be completed by early 2014, at which point the Company expects the Makeevskoye Facility to have a capacity of more than 65 MMcf/d. The Company expects that capital expenditures for this project will not exceed U$6 million ($1.8 million net to Cub).
