Operational Update
Team B commences sidetrack operations at well M-195 in
Azerbaijan
Calgary, Alberta, April 18, 2017, Zenith Energy Ltd. ("Zenith"
or the "Company") (LSE: ZEN; TSX.V: ZEE), the dual listed
international oil & gas production company, is pleased to
announce that the local drilling contactor operating as 'Team B'
has initiated a sidetrack operation at the Muradkhanli field well
M-195. This sidetrack has required the arrival of a more
sophisticated workover rig operated by the local drilling
contractor. The Company confirms that this new workover rig has
arrived to the well site location and that sidetrack activities
have begun today, 18 April, 2017.
Team B was successful in removing several obstructions and
fixing a previously observed casing displacement at the 2780-meter
level in this older well which was first drilled in 1980. Milling
and reaming operations were then continued to a depth of 3026
meters and in the open-hole section below. Unexpected difficulties
were encountered in the open-hole section due to various amounts of
metal debris which prevented the completion of workover operations
aimed at installing a new casing screen. After extensive
consultations with the local management team and industry experts,
Zenith's engineering and geological team has decided to proceed
with a sidetrack operation in order to reach an undisturbed section
of the oil-bearing reservoir with greater oil producing potential.
A window will be cut in the 168 mm casing at approximately
2955-2960m depth and a 139.7mm bit will be used to drill a
sidetrack hole to a depth of approximately 3020 meters while taking
gyro-directional surveys to monitor the direction and inclination
of the sidetrack hole. A 114.3mm casing will then be cemented in
the new hole and a slimmer hole will be subsequently drilled to a
total depth of approximately 3065 meters. This section of wellbore,
from 3020 meters to total depth, will be left as open-hole.
The Company will provide a final update when operations at well
M-195 have been completed.
Dr. Dario Sodero, Senior Geologist and Director, commented:
"When re-entering older wells, it is often impossible to predict
the exact conditions of the casing and what kinds of metal debris
may be found at the bottom of the well, especially when dealing
with 'Soviet era' drilling and completion techniques. It is
unfortunate that the M-195 well could not be completed as per the
initial work programme; operations conducted by Team B have however
proved to be a good learning experience for Zenith in Azerbaijan. I
expect that Team B will be very proficient in drilling the
sidetracked hole with the valuable consultancy of international
directional drilling experts. I am confident that the new
uncontaminated section of reservoir rock will yield good results
when placed on production. This would reward the Company's decision
to begin the workover programme specifically at well M-195 which,
whilst relatively more challenging than other wells, has excellent
production upside potential."
