HOUSTON, TEXAS -- (Marketwire) -- 03/12/13 -- Cub Energy Inc. ("Cub" or the "Company") (TSX VENTURE: KUB) announces an update on its operational activities on the Rusko-Komarovske ("RK") licence and the Makeevskoye-16 ("M-16") well in Ukraine.
Rusko-Komarovske Licence (Western Ukraine)
The Company is in the process of acquiring the necessary permits for the drilling of its initial well, the RK-22, on Cub's 100% owned and operated Rusko-Komarovske licence. The Company plans to spud the RK-22 well in mid-May 2013.
Makeevskoye-16 Well (Eastern Ukraine)
The M-16 well (see notes to editors), which reached a total depth ("TD") of 4,300 meters on 28 November 2012, and was perforated in the S-13 zone over the gross interval 3684 to 3707 meters on March 2, 2013.
After the well was perforated a slight blow too small to measure was observed at the surface and the well was left open to the flare pit. Approximately two hours after perforation the Company shut in the well and observed a small increase in pressure. After being shut in for approximately 15 hours the pressure had continued to increase and burnable gas was observed at the surface. No flow rates were measured during the post perforation flow as the Company plans to fracture stimulate the S-13 zone. Further information regarding flow-back rates will be released when available.
During the time from perforation on March 2nd to 15:00 hours Eastern European Time on March 7th approximately 1.7m3 of fluid had accumulated in the well and field analysis found that the accumulated fluid closely matched composition of the drilling fluid.
The well has behaved similar to the Company's expectations based on open hole log analysis and plans to stimulate the S-13 zone by hydraulic fracturing are being implemented.
Notes to Editors on M-16 Well
The Makeevskoye-16 exploration well in Ukraine is operated by KUB-Gas LLC ("KUB-Gas"), a subsidiary in which Cub has a 30% ownership interest.
Drilling information and interpretation of wireline logs from the M-16 showed multiple potential pay zones in the Moscovian, Baskhirian and Serpukhovian sections of the well. The S-13 zone is in the Serpukhovian section of the well.
At 4,300 metres TD, the M-16 well targeted the Moscovian, Baskhirian, Serpukhovian and Visean stratigraphic intervals, and is the deepest well drilled to date by the Company. The discovery of potential pay in these intervals, if supported by production tests, continue to support the Company's belief that significant value yet remains to be found in the Olgovskoye and Makeevskoye licence areas.
