Cub Energy Inc. announced the Makeevskoye-16 (“M-16”) well has tested significant volumes of natural gas from a new pool gas discovery on the Makeevskoye Licence in Ukraine.
The M-16 well tested gas from the S5 zone at more than 4.3 million cubic feet per day (MMcf/d). The M-16 is operated by KUB-Gas, a partially-owned subsidiary in which Cub has a 30% ownership interest.
The Company perforated a six metre interval in the lower part of the S5 zone and produced gas at a maximum stabilized rate of 4.3 MMcf/d through an 8 millimetre choke at a flowing tubing head pressure (“FTHP”) of 13,100 kPa (1,900 psi) at the end of a 74 hour flow test. The well was subsequently shut in for a pressure build up and at the end of the 169 hours period the bottom hole pressure was 33,985 kPa (4,928 psi).
The Company plans to tie production from the M-16 well into a nearby flow line, which will take the gas to the Makeevskoye facility. First production is expected in the second quarter of 2013.
Mikhail Afendikov, Chairman and Chief Executive of Cub Energy , commented: “We are pleased to announce this new discovery and are excited by the potential additions in production and reserves it brings to the Company. With its discovery in the Serpukhovian, the M-16 has opened up a significant part of the O and M area to lower risk development drilling.
This deeper potential, together with the shallower potential will give us multiple development locations for future drilling.”
Future Development
The information obtained from the drilling and wireline logging of the M-16 well, together with the seismic data acquired previously over the Makeevskoye Licence, indicates potential for at least three other well locations to fully develop the new S5 zone. Additional wells will be needed to explore some of the new drillable prospects that have been identified based on the success of the S5 zone and to fully develop some of the other zones identified as potential gas reservoirs in the M-16 well.
M-16 Deep-Test Well
The M-16 well commenced drilling in August 2012 and was cased to a total depth (TD) of 4,300 metres in early December 2012. Interpretation of wireline logs and other well data indicated multiple potential gas bearing zones in the Bashkirian, Moskovian and Serpukhovian sands. Three of the prospective zones were in the Serpukhovian with others in the Bashkirian and Moscovian sands. One of them, the R30C zone at 2,503 metres, is already a significant producer on the Makeevskoye Licence.
